FAST intake over a stock LS2 intake
I think it's time to see what will really happen when I put a FAST 90mm intake on to replace the stock LS2 intake. I have dyno records of each change I have made to my 05 GTO and all five graphs are posted on the "Interesting information" thread by Nickn20. I have a cam that is set up for a blower and the ls2 has ls6 heads. I have JBA shorty headers and a K&N cai now with a tune. I also removed the stock rear mufflers and went with magnaflow resonators. The car sounds really good and I hope to make some gains on the top end with the FAST intake.
I'll keep everyone posted on the results. Be watchin'.

Well it ought to yield you a few more horses...get those heads P&P'd and it'll be alot more effective...or get the blower I'm assuming that cam is waiting for.
I'd like to get a hold of a fast intake and TB, but I'm kinda tapped in the $ department right now.

Going for a set of Dynatechs!
I just ordered the Dynatech long tubes for the 05 GTO to go along with the intake. I hope to make around 29 rwhp with the headers alone as I am removing the cats then I am going to get some high flowing heads later. I'm shooting for 420 plus rwhp and then the heads and then the ATI procharger goes on. If I had the $$$ now, I would have done the heads too and would see around 480 rwhp before the blower. I will know by next weekend what the LT's and the FAST 90 do for #'s for you all to see.

P.S. I have a pair of the JBA titanium shorty's that I am taking off the car. Anyone interested in buying them for a good price? Make me an offer.

unless you are planning on putting in H/C or 402 its kind of a waste of money to put Fast intake on a stock motor. Check out this thread

http://www.ls1gto.com/forums/showthread.php?t=49271 Heads/Cam LS2 = Nice gains with FAST intake. Granted not everyone is going to swap in heads or a big cam but at least we know the few who are will show noticeable power gains.
His mods are: Kooks 1 3/4, stock catback (w/x-pipe), HPE S-Cam, ET Performance LS6 stage 2 heads, very conservative HPE tune (not dyno tune) FAST intake (home ported).
I'd say with a better cat-back and a better tune the car would pick up considerably more. The stock 05 cat-back is a known restriction where it crimps down to about half the pipe diameter near the differential.

The results are in!!! I went from 379 rwhp and 366rwtq to 412rwhp and 407rwtq sae corrected on the dyno. Actual was 425rwhp and 419rwtq. That's a gain of 33hp and 41 rwtq. I put on Dynatech LT's also. The next step is a nice set of ET 225cc heads!

I gained 18 rwhp and 14 rwtq, not to mention the much wider power band, in fact, in some places I was 20 more rwhp with this intake setup.
