Hi everybody! My name is Andrew and I'm new to the board and the G8 game but I've been a long time lurker/reader. I was fortunate enough to get to buy a well taken care of used 2009 G8 GT with around 40k miles on it a few months back. I came here to ask you all the experts a few questions and maybe help out too.

My bought my car with a cam with dod delete, heads that have been p/p/m, a cai, 3600 stall, Arh headers with Magnaflow axle back exhaust. My question is this; I want to put my own touch on the car and buy a ported 102 FAST intake and a N.W. 102 t.b. but I've read a lot and it seems everyone is about 50/50 yes or no. I've also read people say it needs bigger cubes also. If you could help me figure out whether it would or would not help with my application it would be GREATLY APPRECIATED. Also what other parts do I need besides the intake and throttle body (i.e. injector spacers) THANKS for everyone's help.

Not very cost effective get a hold of rick and have him port/modify the stock intake/tb.

I thought about and I might go that route but im trying to get the most horsepower out of an intake and tb as possible. Plus the stock tb was ported and polished but ported to much so its giving me problems and I really need a new one.

from the countless stuff i have seen posted about rick and his work i would venture to say it couldnt be that far off power wise to the Fast102 and a hell of alot cheaper

Sorry for the ignorance but who is Rick and how does his ported stocker compare to a ported FAST in terms of money and hp over what I already have.

Rick Crawford- G8-4-Speed on the board

His modified "AirRam" Intake is amazing and puts most aftermartket intakes (ported and otherwise) to shame in flow bench numbers, dyno results, and track results.

He worked for a while developing his intake, this post from him sums it up pretty good.
Its best to have all your mods ready and have it tuned once. Gears, stalls, TB, intakes, ect...

There was two episode of intakes for me. First was porting, tried everything and got nothing. It would flow the same as stock no matter what. 20+ hours in a intake and nothing other than hurting port velocity from making all the runners bigger. Gave up....

Time comes and I get another request for intake work and decide not to give another reponse of "nothing is there....". Over my earlier frustration, it is back to work....This time I got an idea. With flowing heads on a flow bench, you always use a radius plate on the port to make sure you get clean air running thru the head. Flow numbers are terrible without it. This gave me the idea of trying a radiused mold on the knife edge of the port entry in the plenum. POOF! like magic it started flowing better without touching the port. Next problem was coming up with something that's practical, cost effective, and could be installed in the plenum without worrying about it coming un-glued, loose, or have the chance of making its way into the motor. Molds and epoxy were out, couldn't be trusted long-term. Especially with all the oil that gets in to the intake. Looking around the shop I found some tubing and decided to try it, gave the same results. Tried several different sizes, even got a few special cnc's wood dowels from Jeremy, until settling on what I am using now. Finally got an intake that shows promise but will it deliver? Anyone who knows me can tell you it wasn't going to the dyno, it was going the track. If it doesn't go faster, then a better dyno number means nothing....With my car I only installed the bars. No cleanup, no pillars removed, nothing.....just the bars installed. Before the intake, it was running 11.80's-70's @116 with my 2800 stall and 285/40-18 drag radials. Now with a 2600 stall and 285/40-18 BFG KDW street tires. Made two separate trip to the track over two months and 11.70's-60's both time @118-119. On a side note, when just porting the intakes, I had the car as slow as 12.0's @114-115 when I tried to radius the knife edge in the plenum. It really hurt the flow numbers... Tested, worked, now to try and get good results beyond my car......

Virus would be the first, his went 11.90 @116+ at @+1200DA with tires I call "hockey pucks"....also his heads and intake is the first data put on the board to show the flow difference but collectively not separately. He was very helpful with all is support since my data and feedback looks bias....

Jeremy, Brent, Dave, and few other shortly followed and it has been gaining momentum ever since. Jeremy did a back to back dyno pull with good results as was the rest of his combination. Brent finally made it to the track as well as Dave. Brent put the stall stall N/A bar pretty high for such a mild cam running 12.0's at 117 during GONE. Dave had nice gains over his previous 1/4 runs and put tail lights on a G8 sporting the new 250cc PRC heads. John set a PB with 11.67 @119+ just bolting on the intake and running at the track, then went to NewEra for a tune update and settled at 18hp gain. Now with a good Possy on my side it is just a matter of staying on top of everything that comes along with it. Emails, tunes, and the work. All keeps me very busy since this is just a side venture to my other two jobs....

End result: Simple, effective, practical, cost effective, and similar price to other "ported" intakes. Next .....getting separation from the "typical" ported intake circle.:bs: Again, not ported, MODIFIED... But people generally look for a "ported" intake just like they do with heads which means want something that flows better for more power. Problem is nothing "ported" with this manifold really generates much of anything. I have seen some cut out the pillars but you can't measure any gains on a flow bench. It doesn't show anything. The math shows more volume but there is already enough so it is speculation to what it is worth. Plus port flow is still the same so it would be combination sensitive and gains would be minimum to none. Who wants to buy a "maybe"? I have put a ton of work in follow-up, tuning, and advice with all my initial intake buyers and with their help the intake speaks for itself. It isn't just a "ported intake", it is a AirRam with the potential to be faster........

Not here to sell you a ported intake, I don't have any.......

also try googling: "g8-4-speed modified intake" click on the link that shows the flow bench results. Good luck man, and welcome to the boards, sounds like you are heading in the right direction with it!

I appreciate everyone's help and after a long decision and a lot of questioning I decided to go ahead and buy the FAST 102 intake and Nick Williams 102 t.b. Ill let you know how it goes and how much power I got from it. If theres anything I need to know from everyone's experience its much appreciated.

Sub'd for results.

Also rick I'm very interested to see your comparison numbers. We already know that yours will be provide more power per dollar but Id like to see just how much more.

I've seen multiple dyno pulls with both intakes... the FAST is a solid gain on a heads/cam car. They do need some tuning though and I think most people just bolt it on and dont get retuned for it. With the tune its been shown to be around 15-17hp peak to peak over a ported stock manifold, but under the curve can be as much as 35 because the FAST doesnt drop off up top like the stock intake no matter how ported it is. The gains between 6-7k RPM are substancial, almost 35hp on my old car and another member in our group was close to 30hp on a milder setup. I did try a GMPP single plane which of course makes more power but packaging becomes an issue, intake routing, fuel rails, etc..

I have a FAST on my current NA setup and it makes good power although my cam is a little small for it. Probably one of the few on here making over 500 NA, especially on stock heads.

this is true for most "ported" intakes. just for the record, the intake that Rick offers is more so modified than anything else; with the addition of the stainless runners coupled with the "porting" it performs much better than most aftermarket intakes, including the fast. My point is that Rick's Modified "AirRam" Intake is much more than just porting. Porting the stock intake doesnt gain **** on these cars, that has been proven

You can modify the stock intake until your blue in the face but you will never get the plenum volume the FAST has. If Ricks is so awesome then you guys should have no problem dyno'ing higher or going faster down the track then an out of the box FAST manifold, but I havent seen it yet. Do you have a dyno showing the gains that a FAST does with a modified stock intake manifold?

Rich hasnt flowed or ported a FAST yet so nobody knows if his is better, worse, its the great unknown. I do know that if he puts half the effort into a FAST as he does a stock manifold then I know it will perform much much better.

You should have came to ECS then and you would have seen that even your almighty NA setup (thats in Lenny's now?) couldnt cut a better time than mine. And hell, im running a tiny stall, stock gears, full weight, and that POS intake that rick made......Get off your high horse already, surprisingly enough there is more than one good intake setup for these cars...

And did i mention, I could give a **** about dyno #'s?

Id love to get our NC crew together and come up there and mop the track with you guys at your precious MIR :punch::soapbox:

Someone should come up with a FAST to let Troy borrow. Then put his car on the dyno again and run it down the track and compare results. Settle this once and for all!:us_flag:

I have a question. I somehow got my AFE couplet to go over the mouth of the 102 n.w but when I put my tubing from my AFE cai in on the other side it slides right thru. DO I need a different couplet or a 102 cai. HELP!!

I've yet to see anyone beat my 11.31 that you seem to care about, but keep chasing it you might get there eventually. I've moved on to faster things. Lenny only has my old cam, not the whole setup. He still has stock heads and came close to your time. We will see what Ricks headwork and FAST do to Lennys time. If anything he will be closer then you to my old time.

Come on up... we have plenty of track rentals. lol at mop the track, your [email protected] isnt going to mop anything but the bathroom at MIR. You better work on running 10's because right now your bark is worse then your bite.

I wasnt at ECS because I was busy working on my own car, I dont have to pay someone to do it. I've had pretty much every part made for these cars, dyno tested them, track tested them, etc..

Lenny is shipping his FAST to Rick so he can test it. Lenny will be going down the track for sure.

Is Lenny a forum member? User name?
