    well if you plan on going FI then you dont want the FAST cause it brackes under boost(so i heard) but if you are going N/A then FAST is the best way to go IMHO but it cost a lot more!

    I gained 27 hp & 13lbs of torque with my FAST intake over my LS6 intake. That is also with the TPIS 90mm T/B over the stock one with the LS6 intake.

    Not worth it unless you got a bigger cam imo.

    Your car is an 01 and therefore you already have an LS6 intake from the factory. like said above dont change it unless you are planning on a much bigger cam.

    Fast Intake

    I just got MS4 and Ls6 Stage 1 heads and all other supporting mods,ie timing chain oil pump etc. Would a Fast intake be worth the money over my LS6 intake. What kinda hp gains are we talking? 2001 WS6
    Thanks

    Did you do a head/cam on the engine before the swap or is this a STOCK engine with the only the difference between the two manifolds with STOCK engine specs?

    I did the heads which are stage 2 and the cam is a B1 and the LS6 intake with the stock ported T/B all at the same time then I switched the LS6 intake to the FAST intake.

    So here is where you got a base line hp number...

    And here is where JUST the intake manifold switch gave you a 27hp increase?

    You have it right, the FAST intake with the TPIS T/B gave me 27hp increase over the LS6 intake and a stock ported T/B. The heads and cam were with both setups.The car was dyno'd on the same dyno both time's by Livernois Motorsport's in MI.
