Default Fast 102 Comparison

So we have a 2006 Ls2 A6 2.56 gears, with bone stock LS3 heads, 1' 3/4 Lg longtubes, x-pipe through Borla Sports, Comp Custom camshaft, Circle D 3200 stall converter, Vararam, and a Fast 102 as the newest edition to this car. For all of you wondering if this intake is worth the money it seems to of worked for us. This is the before and after the fast intake. Car went 11.42 @ 124.2

It may be cam dependent. Other tuners posted average gains of about 12rw but I recall it was a stock cam car. If youre up for sharing the specs, it may shed some light.

Thanks for the data point.

I guess the FAST 102 LS3 type help a lot for this car. I will be going with the SpinMonster 230/234 cam soon...actually I have it in hand. Now I am wondering again after this test. I was 440/405 with the L92/L76, with the 224/228 114, just the heads milled .020. My question is....does the FAST 102/LS3 2 work better with the cam?

Unported FAST LSXr 102mm intake and factory LS3 style 90mm TB?

Also, did you use the FAST injector spacers?

These are pretty impressive numbers.

Can you use LS2 injectors on an LS3 manifold?

So on a large cammed LS3 with LT headers, would you expect to see a ~20HP/20TQ (+/- a little) increase over a factory LS3 intake after a retune with the new FAST LSXr 102 intake?

Yes but you need to space out the fuel rail up about 5/16"

It's interesting how much better it works at 3k as well as 5200-5400, over the std. LS3 manifold.

So this is a stk. FAST 102?

Wow. That's terrific. Much better than the dyno numbers would lead me to believe. This A6 w/stall & 2.56 gears definitely kicks butt.
