The people at ProCharger have been close marketing partners and friends since our first project together on my 2004 GTO Justice. They have been unbelievable when it comes to technical support and customer service as well. This thread is not about who makes the best product. I expect the product to be great and I expect the service to be great whenever I do business. I am often disappointed. It was a bit of luck that brought ProCharger and Pedders together. It is the customer service, the support the people at ProCharger that have them rated as #1 in my book.

If you have not already seen it, I have written an evaluation of the G8 from a suspension perspective. Click here for the JusticePete Pedders G8 Evaluation (http://www.g8board.com/forums/showthread.php?t=1859) The suspension installation is complete, although I am behind on posting more pictures. I have been driving the new Pedders G8 GT from Brain Harris Pontiac Buick GMC Pedders in Slidell, Louisiana to Fastlane in Houston to Lester's in Boerne, Texas to my next stop ProCharger in Lenexa, Kansas. Here is the link to the Pedders Almost Live eXtreme Install (http://forums.peddersusa.com/showthread.php?t=328)

The next step is up to ProCharger. They prototyped the GTO blower kit on a couple of GTOs I provided. They are going to do the same on the Pedders G8. The plan is to have the car ready to go for the Hot Rod Power Tour, The GTOAAs, the LX Nationals (yeah I know, but I did own an original HEMI Charger back in the day so I am really cheating on them when I buy from GM) and the Camaro Superfest all in June. We want to have a show piece of the latest and greatest technology that looks like a piece of automotive jewelry.

ProCharger will release digitals to me as they go through this build so we can post them here. Now that I think about it they can post them right here. We'll also keep you informed on the dyno runs. The car is box stock at this point aside from the Pedders eXtreme suspension. The coilovers are polished chrome -- pure eye candy that works. The ProCharger installation will be SEMA and show car ready. The line for ProChargers forms to the right -- as in right behind Pedders.

Geez, the work never stops. I am going to need a new digital for my signature that shows off the ProCharger FI system....

Well, I must say I'm really excited that there is now/going to be at least 3 options for FI and the G8.

Best of luck on the install. I will be watching, still haven't decided which route I want to go and it will be a while untill I leave the NA world behind.

How do centrifugal superchargers compare to roots-types in regards to low-end and mid-range power?

Procharger already has the goods for the Fall release G8 GXP LS3 M6 tranny. That's my car. I dont see how anyone ( with a performance oriented mind set) would waste their $$ on the 42-45 less hp in the G8 GT and wait for the real beast.

If you're talking about a track car, I suppose you're right; the GXP may be the deal. However, if you're talking about normal driving and a little stop light racing here and there, the GT can be supercharged to 500hp and still cost less than (the assumed cost of) the GXP making it a much better deal if you're satisfied with the GT's mild-performing brakes, suspension, etc and can live without s a GXP's moderate-performing equipment (because, let's face it: the GXP isn't a race car either).

Exactly. If you know you're going to mod anyway, why not start with something cheaper.

6-8k is not pocket change to most. I think 90% of us would take a gxp over the GT. That's why you see all of us bying the GT over the Sedan. Little bit more $ gets you a lot nicer car. Only category the gxp loses in is gas mileage.

Many feel that putting 6-8k into the gt is better than having a stock gxp. Now if you can afford 8k into a gxp. You got yourself a car that most vehicles can't touch.

A very intelligent response to a non intelligent original post. Let's take your street scenario even further. If your going to do extensive modifications, that is suspension, engine, tranny, etc then even in that case dollar for dollar the money is overall better spent on the GT model. If you took a total of of $48K for the GT vs the GXP that would give the GT 16K for mods (32K sale price) and give the GXP 8K for mods(40K sale price). Logically it would be very easy to make the GT faster, handle better, and probably stop better. All the LS3 engine is a L76 without DOD and a different cam and tune. If your going to do serious mods then your going to change the cam and tune regardless of which of the two engines you start with. So if your going to do any kind of mods for better performance then the GT is the less expensive platform overall.

Actually, I think the L76 is 6.0L while the LS3 is 6.2L.

Same block though I believe... Someone correct me if I'm wrong.

...

No, the info is in the LS2 thread on this forum. They both share a 4.06 in bore and the same stroke making them both 6.2L or 376 cubic inches. The LS2 was a 6.0L engine or 362 cubic inches. Again the only difference between the two engines L76 & LS3 is the tune, the cam, and the DOD.
If what you say is true, why does Pontiac define the L76 to be 6.0L?

I was incorrect, the L76 is 6 liters. My apologies for the original post, as my source of information was incorrect. I'll stand by my other comments that the difference in horsepower is going to be very small between a like modified L76 and LS3.

Agreed. There are too many other factors, making a 3% difference in displacement insignificant.

I'll also agree with you that the differences should be minimal. A little more work on the front end to remove the DOD/AFM parts, but otherwise very close.

Agreed, however I'm supprised this thread got this far w/o someone mentioning the gxp and manual tranny. Personally not a concern of mine, as I would go auto either way, but to the true enthusiast, the stick may be the best reason to shell out another 8k.

the rest is just badges and some real comfy seats.

How do centrifugal superchargers compare to roots-types in regards to low-end and mid-range power?

Back to an on-topic question. There's plenty of information (and opinions) on the internet if you're really interested, but basically a procharger (centrifugal) is best described as a belt-driven turbo. In other words, it builds less boost at low-rpm than a roots-type, but potentially allows for more top-end power. Less low-end "no traction in any gear" torque, but less parasitic drag at high-rpm producing better peak power numbers with no fall-off at high-rpm. So it all depends on preference and price, really.


Pete, are you guys replacing the cam/lifters/springs to remove the DOD feature? If so, will it be a similar grind to stock, or are you going full blower cam? What kind of power are you expecting to hit, or what number are you shooting for? I know Prochargers have made crazy horsepower on modded LS2s (and LS1s), not sure how hard you're planning on pushing the engine.

The install that will be done on my car is designed around a box stock engine. They will change the injectors and the plumbing up to the MAF and tune it. The tune will be fat to protect the motor at the expense of power. My net at the wheels on the 5.7 LS1 in the GTO was 463 to 493 depending on the dyno. We are hoping to get 500 RWHP on the L76 because of the plumbing. The Intake and the Exhaust seem to be very restrictive. I'll be running a Corsa exhaust and a custom tune.

As far as the suspension on the GXP my opinion of the HSV advanced adaptive suspension is it should stay in AU. One of my mates is working with HSV to have their car delivered with a standard suspension so it can be upfit with Pedders. He is an employee of Pedders and shared my prejudice. The adaptive system they use is no where near as sophisticated as the AMG CL65. That is a stellar system.

I have had excellant results with my DBA / AP Racing setup on the GTO and plan to use a similar system on my G8.

The shift points in the transmission are so biased towards fuel economy I am amazed at the performance we get out of the G8. There seems to be substantially more torque in the L76 than in the LS1/2. The G8 pulls extremely well box stock at higher speeds. My guess is that my ProCharged G8 will be faster than my ProCharged GTO. I'll know a lot more by May 20th.

ProCharger already has a blog running on MY G8.

I have been told that more than once so when I got my first ProCharged GTO (I think we did three -- can you believe I lost count?) I had them delivered with spare belts. I never needed a spare belt. I never had one jump. The first GTO we did did have a belt fall off, but that was only after the guy who bought it tried to take a tree down with it. It could be that I don't drive my car hard and if you believe that one I have several bridges to sell you.

Not many people are fortunate enough to spend time with thier families while they work. Becuase I do travel so much, I occaisionally bring the family with me. We travelled quite a bit in the GTO -- which is hard to do since there are five of us and only four seats. The G8 makes it easy. We intend to caravan to the GTOAAs with the GTO and the G8. I hope to see many of you from the G8 board at the GTOAA AUtocross. Rumour has it that next year the Pontiac and GTO clubs will hold a joint convention and Pedders will sponsor that autocross as well.

The FI guys tend to use FI to go fast. Imagine that. In the GTO community we have lost to many people to accidents. One of the best ways to learn your new G8 is to run an autocross. Please join us in Saratoga.

Not to complain but I was following your links on your pedders site for the G8 and looking at the Track eXtreme and the section seems to be incomplete. I dont think it has all the parts listed and the description is the same as the track II. Can you update the page or tell us what the difference between the track II and Track eXtreme is?

Also I am not following the earlier conversation, what about the GXP's suspension are you talking about? I am not aware of the suspension on the GXP model coming in 2009, what info has been released? I am worried the extra money for GXP will be wasted if you were to change most of the parts to aftermarket anyway. Although I do want a manual so it doenst matter.

I think this is right... but I am getting older. The list is shorter because you have only one part number listed for the coil / damper at each wheel.

Track eXtreme The Track II combines all the components of the Street II and adds sway bars, bushes and endlinks. With the virtual pivot point design and the advanced rear suspension you tracked G8 does not need to e over sprung and over damped. In complete OE trim it will out perform many respected marques. With a Track II System we are going hunting for the big boys with big dollar stickers. We add more urethane bushes to create greater control. These are Pedders exclusively designed urethane bushes that use voids, shapes and volume of urethane to increase control while maintaining an OE like ride. There are no squeaks. It is not rough. It is AMG like control. It has long been the Pedders philosophy that sway bars are not used to correct deficiencies in your suspension. Sway Bars are the final tuning step for a properly sprung, damped and bushed vehicle. Pedders sways offer four positions of adjustment front and three positions of adjustment rear. They include Pedders HD endlinks and urethane D bushes. They are perfectly matched to provide an amazing level of control as they compliment every elements of your Pedderised G8.

For those that are going the mod route the biggest advantage of the GXP will be their preference for a stick shift. On my 04 GTO we replaced, suspension, brakes, exhaust, seats, wheels and added a ProCharger. If I purchased a G8 GXP I would still replace the suspension, wheels, tires exhaust and add a blower.

Everyone is different. In the LX community my feeling is that the SRT 8 buyers / owners are really more interested in the larger displacement engine and increased RWHP. For my money the real advantage of the SRT 8 is the Brembo brake upgrade. The GXP will have Brembo brakes so that my be the best most improved part of the GXP. I can live with an automatic in my four door luxury sedan G8. I just hope my automatic transmission can live with me. As I said I am slowing down in my old age.

We are hoping to get 500 RWHP on the L76 because of the plumbing.

You plan on adding 195.41 RWHP with how much boost? I do not see you getting there on pump gas on a stock motor. With the average gain @ 20 HP per pound of boost (in a perfect world) you would need to run 9.77 pounds of boost (call it 10). On pump gas @ the factory compression ratio? Not saying its impossible, but the planets would sure need to line up to make 10 psi happy on the street (on pump gas) and still maintain the dependability of the vehicle driveline.

Yeah thats what I mean, thats the exact same description of the track II and track eXtreme. One is $3121 and one is $4177. Whats the difference, they have the same description. $1000 price difference and no explanation. Yeah different parts but an explanation in what the eXtreme does would be helpful.

And yeah I test drove a G8 and told them I really wanted a manual. Also the big difference is the rear gearing, I think the GT is 2.92 and the GXP is 3.42 auto 3.73 manual, although I fear with 3.73 and forced induction I have no idea how launching will be possible haha.

Mine are chrome and the production versions are powder coated.

Oh god those chrome ones are purdy..... mmm anyway how big of a difference do they make?

Our GSR dampers and SR coils are roughly 30% higher in rate and on the critical damping scale than OE. Moving to the eXtremes we are now closer to 60% higher. The GSRs and SRs put the G8 into BMW M or AMG handling ranges. The G8 is an exceptionally well done car. The eXtreme, this is just my OPINION and that of a Mercedes AMG 12 cylinder four doors felt remarkably like the AMG over 100 MPH in terms of ride and handling. The real cost of the eXtremes is not measured in dollars -- they ride quality is more BMW M3 / Audi hard sport than luxury sedan. The coilovers on the G8 are not for everyone.

That said, I wouldn't want anything else.

OT, but Pete, do I understand from your first post that you live in Slidell or you just bought the car there? I live in Kenner and would love to see your car in person sometime!

I got to ride in his car at the Midcoast performance open house last weekend and it defentatly performed great. I felt the suspention was not overly ruff but very stiff and stable. He did some S and circles to show the difference and it was night and day over the stock version. I don't think the stock is bad but you could defentalty tell a difference and the power from the procharger was unreal but he still had the transmission lag that will have to be addressed.

When is this kit going on sale????????

If you're talking about a track car, I suppose you're right; the GXP may be the deal. However, if you're talking about normal driving and a little stop light racing here and there, the GT can be supercharged to 500hp and still cost less than (the assumed cost of) the GXP making it a much better deal if you're satisfied with the GT's mild-performing brakes, suspension, etc and can live without s a GXP's moderate-performing equipment (because, let's face it: the GXP isn't a race car either).

ditto

I picked up the Pedders ProCharged G8 on Thursday....

ProCharger did nothing short of KILLER QUALITY WORK!!! I can't thank them enough. The installation is OE with Bling. The water-jet cut polished aluminum brackets and blower are nothing less than automotive jewelry. I felt like one of the guys on Overhaulin that keeps saying Holy S---!!! OMG -- WOW!!! Give me the keys -- NOW!!!!

The RWHP -- you'll have to wait. ProCharger has not released the numbers for the G8 kit. I can tell you they had my G8 running at my dream number. I can tell you they really liked the fat and flat torque curve. I can tell you that my car is not at my dream number today -- but we'll get it there. If you would like to read more here is the link.

Any curves yet? I can't wait to see those "fat and flat torque curves"

The GXP is going to be a NEARLY track ready car as it's suspension is being honed on 4 different tracks. It's going to be a far different animal under the hood and suspension than the weak kneed G8 GT. I've driven a Proto GXp back to back with a GT and all I can say is OMG!!!! the GXP walks, almost runs away from the G8 GT in acceleration, and handling is in the 0.92g range vs the GT's 0.85 , better mpg's too.

Your dream number better be above 500 rwhp.

Tune, a cam and heads, nothing else and you've got a 510 bhp GXP, do the same to the GT and you've got 390-395 rwhp! I'll take the slightly lighter ( sticks are typically 60-120 lbs lighter do to less rotational mass) more powerful, much better suspension and the extra 6k I pay for the GXP any day over the same mods on the GT. The LS3 is a lighter motor too, 35lbs to be exact. Don't forget to toss the run-flats,as they are 10lbs each heavier than similar performance tires, that's another 35-40 off the car.

For not much coin you could have a NA GXP that'll put down CTS-v levels of Assisted power if you factor in bolt-ons to the above GXP and now you have another 40+bhp for a nice round 550-560bhp. and 200 lbs lighter then the new V. Yeah, that's what I'm talking about. Supercharge this equation and now you've got a near 700-710 bhp beast on 8psi, turn it up to 10 or 11psi and 750+bhp, yeah baby!!!

GXP's in testing with just a re-tune (as GM sends them out with weak tunes for EPA and such) are going from 405 bhp to 435-440+bhp!! with just a re-tune, 15 minutes and $100 later.

You plan on adding 195.41 RWHP with how much boost? I do not see you getting there on pump gas on a stock motor. With the average gain @ 20 HP per pound of boost (in a perfect world) you would need to run 9.77 pounds of boost (call it 10). On pump gas @ the factory compression ratio? Not saying its impossible, but the planets would sure need to line up to make 10 psi happy on the street (on pump gas) and still maintain the dependability of the vehicle driveline.

What do you porcharger fans have to say about this. . . I want to know which supercharger kit is going to be better over all. . . the procharger that everybody is talking about here, or the MP1900 made by Magnuson ?

lol thats a silly comparison. I mean a procharger has so much more potential for expansion ie p1sc d1sc f1sc f3 plus pulley swaps need I say more. Maggies will only give you but so much power on a smaller pulley until there completely maxed out.

Whats p1sc d1sc f1sc f3 ?

The different procharger superchargers that procharger offers. Plus imho centrifigual superchargers like the procharger create less heat than a roots super charger like the maggie = more consistent hp and tq numbers.

Perhaps pre-TVS you would have been right, but now that the 1900 and 2300 6th generation rotor groups are out, to put it simply, you are wrong. :judge:

Well its all in a matter of what you want low end punch maggie or more high end punch procharger. Theyll both make great power but its basically up to what you want :)

thanks for the help guys

No updates yet?!?!?!?!?!?!

It really doesn't matter at this point. Until they find a better place for that intake than the hottest spot under the hood no one with any serious knowledge and desire for performance will buy the Procharger.

Do these procharges come with some type of intercooler ? Sorry for newb question...looks CRAzy under the hood...almost turbo like.
If its making over 100 + more hp to the rears...that seems like a serious gain IMHO

ProCharger uses large air to air intercooler. The exhaust gas temp on a ProCharged G8 like mine has a slightly lower temp on a 90 degree day than an OE engine.

Ball park on when we can expect a cost and dyno number? just curious
I guess when it comes to FI ...everyone has an opinion...I am no expert...I think alot of posters have there own interpertation of what works and what doesnt....but it looks like a pretty good set up IMHO
I am looking for best combo of price vs performance gain and reliablity..
Anyone with time on there hands care to draft out a comparision of numbers for the FI currently out there?

I'm not saying this thing won't generate more power than stock, but you'd get a lot more out of it with some colder air going into it. It's simple physics.

ProCharger and Pedders have a relationship going back to our first SEMA project in 2004. ProCharger has done four or five cars with me. They have been almost trouble free which is amazing considering the installations were all prototypes. The people at ProCharger are first class. Honestly the people are more important to me than the product. Because they have such good people, because the product support is so strong I highly recommend doing business with ProCharger. Not because of technical superiority but because of people superiority. I am sure that there are other high quality blower companies in the market. They also should have high quality people. The difference is that I don't know themand don't have yeasr of history working on new projects. That make ProCharger my first choice in superchargers.

The kit should be available soon. I would guesstimate the price to be about the same as the GTO kit. You can read more about the complete build of the Pedders USA, LLC G8 on our Almost Live Build.

A procharger is a supercharger that acts like a turbocharger - it doesn't start building significant power until you get higher in the RPM range.

Prochargers are belt-driven turbochargers essentially. Both turbochargers and prochargers/vortech/paxton/powerdynes are all centrifugal compressor forms of forced induction. The primary difference is the manner in which the compressor is driven. With a turbochager, you have a turbine which drives the compressor side (connected by a center-shaft). With a centrifugal style supercharger, the compressor is driven by the crankshaft via a belt (and pully/gearbox/transmission assembly). Turbochargers typically can be spun to significantly higher speeds than a similarly sized centrifugal supercharger. Typically, with similar sized compressors, a turbocharger can create more flow. The boost threshhold (point at which the transition between vac and boost occurs) between a turbo and a centrifugal supercharger may be similar (usually only if the turbo is leaning towards the larger end, relative to the engine size/exhaust energy). However, the boost usually ramps up exponentially quicker with a turbo than a centrifugal supercharger, reaching max boost pressures significantly sooner.

Personally, I do not think turbochargers and similarly sized centrifugal superchargers act anything alike. Centrifugals tend to manage traction much easier than turbochargers (especially on the street). Turbochargers can provide absolute violent speed if you are looking for that. Turbochargers provide a seemingly endless rush of torque. I've owned numerous setups with both forms of FI. It really depends what you are lookfing for. Personally, I would go with a twin-screw/TVS roots or a turbocharged setup before a centrifugal supercharger.

A procharger is a supercharger that acts like a turbocharger - it doesn't start building significant power until you get higher in the RPM range.


I didn't see that in the ProCharger dynos, not to say that there used to be a comparison to a turbo.

So my choices are a ProCharger (belt driven turbocharger), Magna charger (a supercharger that sits on top of my intake belt driven), and or APS twin Turbo (expensive as hell and way more power then i am looking for).
Is there a company that does a single turbo because I am looking for 450hp to 500hp max???!!?? and I don't want to spent a assload of money!! Any suggestions??

Ride in one of each vehicle (turbo and Procharger) and you would be able to feel the similarities, just as if your rode in one of each vehicle (Magnacharger and Procharger), and you be able to feel the differences.

Why? Do you disagree that a centrifugal has very little boost in the lower RPM range, with increasing boost into the higher RPM range, like a turbo? What is it that you disagree with exactly?

Typically, if the turbocharger is sized properly, a turbo should not act like a centrifugal supercharger unless it is grossly oversized for the engine. A centrifugal, by it's nature, will not reach it's maximum boost until redline (or whenever the engine reaches its max rpm).

ex) Centrifugal Supercharger

2000 rpm - vac
2500 rpm - vac
3000 rpm - 0 psi
3500 rpm - 1.5 psi
4000 rpm - 3.5 psi
4500 rpm - 5.5 psi
5000 rpm - 7.5 psi
5500 rpm - 9.5 psi
6000 rpm - 11.5 psi

ex) Turbocharger

2000 rpm - vac
2500 rpm - vac
3000 rpm - 1 psi
3500 rpm - 3 psi
4000 rpm - 10 psi
4500 rpm - 11.5 psi
5000 rpm - 11.5 psi
5500 rpm - 11.5 psi
6000 rpm - 11.5 psi

That only supports my claim that centrifugals act like turbos more than they don't.

Compare the below graphs to those of a modified-roots like the Eaton M112:

1500 rpm - 11.5 psi
2000 rpm - 11.5 psi
2500 rpm - 11.5 psi
3000 rpm - 11.5 psi
3500 rpm - 11.5 psi
4000 rpm - 11.5 psi
4500 rpm - 11.5 psi
5000 rpm - 11.5 psi
5500 rpm - 11.5 psi
6000 rpm - 11.5 psi

Just had to add another line for 1500 RPM where neither the turbo nor the centrifugal ever make boost. :)

That is an overly simplified example I just threw up there to make a point. Apparently you have missed the point. Centrifugal superchargers inherently flow/compress air in a linear fashion. Turbochargers do not. I can get into the dynamics of the compressors if needed. PM me.

Have you ever owned a turbocharged car or a centrifugally supercharged vehicle before? The turbocharged vehicles I have owned or driven act nothing like centrifugal superchargers. I have owned both centrifugal SC-d and turbocharged vehicles. I'll throw you a bone though. Go graph two identical cars (less the form of FI). One car with a turbocharged setup and one with a centrifugal. Go look at the torque curves.

I am interested to hear what kind of turbocharged setups you have driven which have acted relatively close to the of the centrifugal SC-ed setup on the same vehicle. If you have any details of the setups (including the centrifugal setups), do provide.

Just a follow-up note. I'm not bashing centrifugals. There are pro's/con's to all FI setups. Simply stating that I have never heard anyone compare the driving/power production characteristics of a centrifugal to that of turbochargers.

Here we go again. The only test will be to drive each car individually, and make your decision from there. I'm putting my faith and hard earned money into what suits my personal preference. It isn't about past experience, it's about what the G8 really has to offer. Up untill this point, I really don't think there has been anything to compare it with. Unless I'm missing something beside the space bar?

Obviously there will be a difference between the two. I think throwing Procharger into turbo class on this one is a little off base, that's all.


10-4. I have owned PD(twin screw)/centri/turbo/N2O cars before. All have different characteristics. I can say this with 100% certainty though. Centrifugal cars and turbo cars have vastly different characteristics. Centri's torque is relatively easy to manage. This makes for good street driven characteristics in high hp applications (over 550 rwhp). Less traction issues. Turbo's IMO are the most difficult to tune (again, the exponential rise in turbine/compressor wheel speed) and manage traction on the street. PD SC's provide immediate torque, but you can modulate it with the throttle. Due to the fact that they are exhaust energy driven, turbochargers do not have as much of a direct input/output controlability that belt driven SC's do. In higher hp applications, turbocharged cars can be very difficult to manage on the street (I had a 1000+ rwhp mustang cobra...even at 8 psi/550 rwhp, traction could be pretty unpredictable). Again, pro's and con's to all setup's. Personally, I would probably prefer a positive displacement setup on this car if I wanted it as a daily driver. The immediacy of the torque is GREAT (plus...this is a 4000+lb car, so it helps to get the car moving).

The ProCharger installations on the three GTOs and G8 Pedders has done with ProCharger have been virtually flawless in daily driver and sporting use. The power is there when you want it while th car remains very civil. I had never missed any track time with the ProCharged GTO until the GTOAA Autocross. The MAF gave up the ghost. That failure was probably not a result of the ProCharger and cover almost 5 years of use and abuse.

If you are looking for 500 RWHP it is available with a bolt on CORSA exhaust another 60 days away and a ProCharger this month. Are they the best -- I can't speak to that. I can say I wouldn't trade mine.

The ProCharger winds up really nice with the Corsa exhaust prototype.

We welcome your comments on the exhuast note.

We're just about to order the first Pro charger kit for a VE Holden SSV commodore eg mine in a day or so.. How did I make up my mind to go with a procharger.. simple..

I've been in turbo setup cars and while the power increase when at full spool gives you that all at once push back in your seat and breaking of traction.. it is un predictable and not something I'd have my wife driving around in.. also some turbo lag in there before hand..

I've also been in a pro charged stock LS1 holden monaro 6 speed.. and omg! the power delivery was so smooth and progressive which i really liked.. not to mention the almost turbo like intercooler flutter on gear change :).

I've owned a cammed up 400rwhp VY SS holden Ls1 before my ssv and that had a great note and lumpy idle.. with alot of pull from 3000rpm to redline.. 228/230 cam @ 112 LSA.. and I would take the procharger over this setup.. stock manners with the go when you want it!

After the ride in the Monaro coupe.. I said to the guy.. "stuff the cam and heads on the SSV, Procharger straight out!.. im talking some amazing pickup and 470rwhp on this Stock LS1 with only cat back exhaust, tune and procharger at 6psi..

Should have my ssv/g8 procharger fitted by the end of this month.. first one to be done here in west aus.. and am hoping for around 450-500rwhp on stock motor with stock exhaust.. by the way we run on 98 octane fuel here!..

On another note.. the top mounted harrop,pwr chargers that run water to air coolers.. on LS1 motor and LS2 with full cam and exhaust/tune setups are only doing around 480rwhp but that id say is on about 6-7psi aswell.. they're fairly loud too btw. So to get 450-500 rwhp and stock like manners with the procharger only and tune is damn good imo!

Well, kind of, but not really. :)

The UK, South Africa and Australia use the RON (Research Octane Number) method, whereas we use the (R+M)/2 method, or (RON+MON [Motor Octane Number])/2.

The (R+M)/2 method is usually 4-5 points lower than the RON method, so your gas is essentially no different than our 93 octane.

Yeah thats true 98 ron lol though some octane booster doesnt go astray ;)

No rating over 91 in the south west and western US.

Drag Run at M13 last Saturday. The car still gets loose on the up shifts, even with the traction control on. I try to moderate the wheel spin by backing off the throttle a bit... the new Forgelines and Bridgestones should help on the up shifts.

Just wondering what you guys were experiencing with the sound of the procharger unit inside and outside the car with the hood closed... I'm really torn between the procharger and the maggie and am just trying to find out as much info as I can before choosing. I know that you guys have been partners with procharger for a long time and I can tell that you think their system is top notch. However the whistle/loose belt sound that comes from procharger units that i've heard is not for me, i understand that the blower whine is what is so addicting to FI guys or whatever but it's just personnal taste to me and I think if I could have the smooth power delivery and endless top end of the procharger without that noise at idle I would extremely impressed. Just wondering what the Pedders Guys thought

The ProCharger whistle is more noticeable at idle than at speed or inside the car. The Maggie is more noticeable at speed inside the car and under hard acceleration while at idle barely audible outside the car.

How is that for almost no help?

HAHA... right about back where we started:)... Although if I couldn't hear it inside the car that would be great and awful at the same time because it really makes this decision difficult... haha, thank you very much for the response though!

What kind of oil coolers did you get? I want to buy a trans cooler... Meanwhile, im still waiting for my D1SC kit... it's suppose to arrive sometime this week... Are you guys thinking of adding a water/methanol injection kit?

With a few more tuning tweaks we will get from 480 to 490+ RWHP without any water or meth. I'll leave it there as my ProCharger experience on the GTO and G8 have been highly reliable in this power range. The car drives so well like this. I am goo to Gooooooo!

Cool! Do you a part number for the trans cooler?

ok sweet :) should have the car back by thurs or fri hopefully :).. The SSV runs the L98 6L just doesnt have the dod stuff in it.. we usually find the L98's run a bit better than the L76's in the older model vz's here..

It's a 6 speed manual too so should be interestng to see how it goes with a little less drivetrain hp loss.

hmm for some reason i cant view the 7th page.. i click on 7 and it keeps taking me to 6 lol

yeah i know, that's weird..

So how is the G8 fairing with the air intake up above the exhaust manifolds? is the intercooler doing its job well for temps?

The IATs have been no higher than 94 on a day the exterior temperature on the radio display showed 94. The same was true on a hot day of dyno tuning. Obviously the location is less than ideal, but space is at a premium. I have been talking with several people about a cowl induction hood for the G8.

^ That's what I'm talking about!

^ That's what I'm talking about!You like the idea of a cowl induction hood?

For this setup yes. I've been a fan since my dads Chevelle. :) Although, Im sure its going to be hard to tactfully pull it off on the G8.

We'll see how the designer does and then we will both know.

Look forward to hearing about it :)

We'll get hard at it right after SEMA. The designer is out of Detroit and has done some really sophisticated work. Maybe he will stop by the thread and give everyone a preview or maybe at least an early sketch.

Hey guys, i just got my procharger kit. The only thing that i noticed that's different from yours (JusticePete); is the surge tube.

The unit on my G8 is a recirculating prototype. So far so good. The end result is the same. You are about to find your rear tires last about 1/3 as long as they would have :):):):)
