FAST Intake over LS6.. Hey guys-
Are the gains that much better with the Fast over the LS6 intake?
Also, I'd need to pick up a 90mm throttle body, right? The stocker is too small?
Thanks
Jeff

A 90mm will go with a FAST intake, but they also have the 78mm option. It's up to you and how much your wallet can take.

I dont have any dyno numbers but I herd 15-20rwhp gains but for 1000$ its kinda high. so I put it off for a long time and a few months ago I broke down and bought one I can say it made a nice SOTP fell car seem to pull much harder at high RPMs and at the track it gained .2 and 2 mph in the 1/8 to me that was a nice gain

I can attest. I wen from Ls6 to FAST 90/90.. and omg 15+ hp/ real nice boost in sotp department. It;s probably the best intake out there for the money. Yes, I know, it's bout 1000-1200 all said n done, but I think it was worth it.. then again, I'm all bout squeezing the hp from the cubic inches.
good luck on you decision

I just finished up my FAST 90/90 setup today (took about three hours) and all I can say is wow. Right off the bat I can tell a huge difference in throttle response and the mid range is awesome. I haven't been able to go WOT through the gears yet but it's coming. Mine is a H/C car and it woke it up big

****..yeah for some reason i was thinking LT1. Been studying o-chem way too long so it has my brain fried.

not exactly "top shelf heads and big cam combo' as you so aptly say...
