Default Another Fast 90 Question

Hey guys. I got a chance to pick up a Fast 90 Intake for a really good price right now. I'm just wondering how much I would gain with the Fast or how much I'm leavin on the table if I stay with my LS6? I've done a bunch of searching but havent come across any real world data. I was plannin on doin some 3.90's in my car and I can't decide what would be a better choice for my daily driver? My mods are in Sig. Thanks in advance!!

With your mods I would think it would be a significant improvement. I would count on 15-20 but not be surprised with more based on claims from this site.

Especially if you clean up the areas around the ports as they have some crap in the way of flow.

If the price is really good it might be worth it...depends on how much $$$ you're talking and if you have it to spare. Don't forget you can get at least $300 for your intake and $60-70 for the tb.

If you port it properly, then you should see 20 rwhp over the ls6, in some cases more. Depends, all engines are different. Best of luck to ya.
