Does anyone have a LS1 w/ a FAST intake, 92 or 102 and 1 7/8 headers w/ stock cam? If so I'm curious to see how much it put down on a dyno and more important track times.

Thanks.

Saw that setup do 335rwhp before. Not sure if the intake was ported. It was a 92 tho

Wow. Hopefully that was on a Mustang Dyno. My car did that stock with a lid and SLP y pipe.

I was shocked when i swapped my ls6 intake/ported tb for a fast 92/92 and only picked up a few hp(less than 10).Don't rule out the ls6 intake.

I'm just gonna say unless you have heads and cam, or just money to burn, the Fast intake is not worth hp per dollar

I agree with you. I was just wondering who had done it.

I did it, with a couple other things. stock cam and heads. I never got it dyno'd but my trap improved quite a bit.

What's "quite a bit"?

i'd rather not say right now. but the fast 92 is a nice piece and 1-7\8 headers are the only way to go on an ls1 IMO. the fast does have a small improvement over stock, and if you plan on modding further it becomes more and more beneficial, especially if you don't car about the money. I did more than the fast in one shot so unless you do everything I did the results won't be comparable.

however if you're running the stock intake and exhaust manifolds now, I would imagine that between the fast and 1-7\8 headers you'll gain 2-3 mph. headers alone got me 1-2.

big hammer

if you have an ls1 intake you'll gain roughly 13ish hp with a fast, and 8 ish over an ls6 intake.

Wasnt a stingy dyno at all. On that same dyno my car did 426rwhp.. From what I have seen the 92 is a soild 10rwhp gain on a heads/cam car over an ls6. Some gain more, some less. I almost bought one.
