Scott was able to finish up the install of his APS kit on his G8 this past weekend. It should be going on the dyno within a week to be tuned. Look for a post with tuning results in the near future.

This was my first installation of an APS kit, and I am extremely impressed with it. Everything seems to be engineered at least as good as O.E.M., and better in most cases. The instruction manual was also very good. I actually did this installation at home in my driveway just to see how difficult it would be for someone who didn't have access to a lift. Lots more information to follow in the near future... :D

How long did it take ?
hurry up with the dyno #'s , dont let the blowers get all the attention :driving:

Wow! Are we talking about a twin turbo on a stock motor. 10 to 1 compression.
Interesting.

:worthless:

interesting...

We own a APS car and have done 4 others. The quality is top notch and OEM quality. I'm always impressed with them.

Is this the same kit? 557 HP?

http://www.autoblog.com/2008/05/12/aps-builds-557-hp-twin-turbo-setup-for-pontiac-g8-gt/

There have been many discussions in AU re "safe" boost on a stock V8.
The accepted approach is NOT to lower compression.
Run a professional tune.
Run with 10psi all day long.
Safe as houses.
550hp at the wheels.

Need some pics of the install, and how long did it take :driving:

Where to buy? Cost? What's included in the kit? I am unable to see the kit on your website. Seems like a nice set-up from what I have read.

Thanks,

The storefront is currently down getting a software update. It should be back up by this afternoon. Along with the kit we also recommend 60lb Fuel Injectors along with wiring adapters, AR 103 sparkplugs, a 160 T-stat and a custom dynotune.

All these items are available from INTENSE and as soon as the software update is completed I'll post links to those items here :)

look out Lambos

We're going to dyno tune it tonight. :D

We'll have to hold back a little bit though, since we still have the stock 2-1/4" exhaust system and fuel injectors for now...

Can you describe then (since pics aren't an option)? I posted the same question on G8GT after someone else's install and I'm very interested in the solution since my area sees quite a bit of rain.

Ooooh man...just when I finally figured out which type of Forced induction mod I may want to go with I see this!!!!

I guess I should be happy with how quickly the aftermarket has responded to the G8.

Maybe I just don't see it, Did youguy's install an intercooler?
Yes, there's an AWESOME intercooler tucked in between the front bumper and the radiator, where the factory air dam and washer fluid bottle used to be. This is a very clean installation. By the way, this intercooler ROCKS. Last night on the dyno, we say PEAK charged air temperatures that were only 15 degrees above ambient. :)

The lowest point of my air filters are still more than 6" from the ground, and my car has been lowered. So I'l just avoid puddles that are more than 6" deep. :p

Yeah, except, the second this place when "pay", everyone would flock to another forum. The internet is a wonderful thing, making your users pay, won't work. Vendors are here to sell stuff, make money. I'm cool with making them pay to advertise to me.

*I* refuse to pay for a forum. I also help run the biggest car forum for New England, so I have a few years of experience. Putting a shop's name in your sig, is advertising. Having the pics link to the shop's page, is advertising. If he didn't have either of these, and just pics, without mentioning the shop, I don't think this would have been an issue.

(notice I didn't mention my forum's URL on here :) )

Well, I'm also a member over at ar15.com.

There is no rule that says you have to make a donation, but you do get expanded features if you do. I consider my $24 a year money well spent.

There are also advertisers over there, but if someone wants to sing the praises of Colt (who is not a sponsor), over Bushmaster (who is a sponsor), there is no problem.

It's not my website, but I just think it's silly.

That's just it, when the first post was deleted I was told nothing, it was just gone.

When the 2nd post was deleted I had deleted any sign of the company from the pics, but I had my profile website set to the shops website, (I don't even have a signature).

For the 3rd post I removed the link in my profile, so there was no sign of the company or advertising anywhere, yet it was deleted again.

Thats just dumb. You could use the same logic that if you post a pic of a Charger, it would get deleted because Dodge isn't a sponsor.

^i agree... this is starting to remind of the first trailblazer SS forum...

Looking Good.:D

Expanded features sets are something completely different. Photo gallery, cool "Titles" and whatnot, yeah sure, people will pay for that. Basic functionality though, I don't think so.

Why dont you all just shut up about supporting vendors. or open a new thread y hijack this one about the twin turbo kit. i hate reading through useless crap not even about the thread. save it for somewhere else guys.

damn dude thats tight... i wanna see some #'s

Great kit for California.

Only issue I have is with the intakes and puddles.

Otherwise definitely looks good. I've installed some APS kits on WRXs and always had good luck with em.

G8 GT Twin Turbo Dyno Video Thread (http://www.g8board.com/forums/showthread.php?t=3187)

I kinda like how quiet it sounds with the stock exhaust. It's stealthy and gives that element of surprise on some unsuspecting prey. But a more free flowing exhaust would definitely sound better and probably produce more power.

At what psi is the stock MAF maxed out at? Do you really think the tune is safe without a map sensor?

^i agree... this is starting to remind of the first trailblazer SS forum...


werd, is it time for another tbssowners.com? guess we gotta get tony in a lowered g8 first.

The Maf frequency that the ecm will read goes all the way up to 15,000 hz. We are no where near pegging the maf. Tuning via the maf is both safe and reliable as long as you are not "pegging" both the out frequency and the max air flow that the ecm can calculate based on frequency. We have made over 1000 hp using a Maf without pegging it. I am aware of twin turbo ford application making 1450 rwhp while using a maf. The tune can be made to be safe as long as the ecm is able to use the signal from the maf.

But what does that frequency correspond to? That's like saying my speedo will read up to 15kHz, but it doesn't mean I can go 300mph (making up numbers, but you get the point)

We're pretty close to 11,500 Hertz right now at 473 WHP, and the factory PCM MAF table gos to 15,000 Hertz. So for all intents and purposes, our stock MAF will easily be able to handle all our future plans with the car. :)

Since im pushing 30yrs old now, I figured I would grow up and move away from the import scene and see what the V8 scene is like. Although I'm a newbie to 8cylinders, I'm not new to performance upgrades and turbo charging. I'm trying to decide procharger or turbos? I'm leaning toward the APS kit since I've owned a couple turbo cars. As of now I drive a 1996 Nissan 200sx FWD putting out 421whp and 365ft lbs. Anyway my question about the APS kit is, that it seems to be a blow through set up and the MAF from what you're saying is larger enough for the Horse power goals you have in mind. But why is the BOV recirculated back into the intake instead of to the atmoshphere?

Nevermind found the answer on APS website. It's not that you can't vent 100% atmoshpere their dual port design just allows better driving conditions by venting it back as well as into the atmosphere.

when you retain the MAF, it's better to recirculate so the car doesn't idle like crap or stall out... i had the same problem in my evo with HKS SS bov...

so does the aps kit run boost based off the wastegate spring only? or do you HAVE to use a boost controller?

Great kit for California.

Not really, unless this thing is CA smog legal. I would not put any performance parts that arent smog legal on my car in CA. Now if this kit is CA legal... then wow is all I can say.

No way that thing is CARB legal. AFAIK, the only aftermarket turbo kits that have CARB exemptions are from STS and are rear-mounted.

I understand that its better to recirculate teh MAF so it doesn't run bad or stall out, I had this problem on my SR20DET, but that was on a draw through set up just like the EVOS. But I converted mine to a blow throuth set up and did not recirculate without any problems. Thats why I was wondering about the APS kit being recirculated, because I noticed it was a blow through setup

And your point being? I thought it was a 5 year waiting point for SMOG here in Ca on a new car? Carb,Carb,Carb, If you can't get around that, why bother!

And your point being? I thought it was a 5 year waiting point for SMOG here in Ca on a new car? Carb,Carb,Carb, If you can't get around that, why bother!

Point being that if it doesn't have a CARB number, it is ILLEGAL. All you need is one snoopy cop (or a speeding ticket, for that matter) to trigger an automatic inspection.

That aside, some people actually like to be legal, even if they are not being pulled over. :judge:

Pretty much, yeah. I hope STS makes a kit for this car that would be incredibly badass. Ive always been impressed with STS kits for a variety of reasons, CARB legal TT is the biggest of course.

You do hear the blowoff valves though whenever you let off the gas. And they sound very cool. :driving:

That's a much different sound than a constant whine from a blower.

Good. I've seen too many videos of S/C V8s with a loud ass whine.
Thats one of the reasons that im not considering a procharger. It has a loud whine at idle.
OK, what about when you are at full boost. Is it really loud inside the car?

It would depend on your exhaust I would guess, but the turbos actually act like mufflers to some extent.

this kit runs off the wastegate spring at 9 psi?

The wastegate springs are set to 0.5 bar (~ 7 psi). You can turn the boost up by installing stronger wastegate springs, or by adding an electronic boost controller. We chose the latter route. :driving:

You don't need long tubes with a turbo system.:slap:

a better flowing exhaust rout is what I was getting at. Improvement can obviously be made.

We use a 3" exhaust system on our INTENSE TT G8 GT. For a daily driver I don't think you are going to get much better flow.
