Boy...at this point it looks like I was the only bastard to vote for the LS6 intake huh? Hell I even own a FAST intake on my car.....but if I had it to do over again, I'd have bought the LS6 and saved a bunc of money. The only reason I got the FAST is because of my Spray.
By the way....this FAST vs. LS6 polls and threads are beat to hell aren't they? I mean....we get like 3 a week!!!!

Well I already have a LS6/ported TB now. I am trying to decide whether the 90/90 would be worth it. Would I see any gain. The car is going to stay all motor. I was just wondering if the 90/90 was too big for stock CI NA engines.
I think its in the low 400 rwhp range as of now. The intake seems like about the only HP mod I have left besides raising compression.

The LS6 is still restrictive. The fastest cam-only guys run them AND the fastest bolton-only guys. Losing some low end is also the nature of the gain when gaining upper end power. There's that curve shift associated with it at times (ex: going from a Performer RPM to a Vic Jr.) that might hurt lowend, but more than make up for it on the top end.
I'll take a 90/90 anyday of the week on a stock LS1 motor fwiw.

The 90/90 will have a certain advantage over the LS6.
