Default FAST LSX intake with stock cubes?

I was planning on purchasing a FAST 90mm intake and tb,and was wondering if I will get a jump in horsepower over my ls6 I already have? I have heard you will not see any difference with a stock cubic inch Ls1,which mine is for now at least?

The FAST intake and tb are a good investment for the future but stay with the LS6 until you do at least heads and cam swap, otherwise you might not get the performance difference your looking for. Just my opinion!!

I am running a Fast 90 intake with Nick williams TB, Longtubes, catback on stock heads and cam. I purchased all of the heavy bolt ons first in anticipation of some hand worked AFR heads, Custom TR Cam and future Forced induction.
I lost a little power down low, SOTP power but noticeable, but i gained uptop..i can break the tires loose at the top of second from a low rpm dig about everytime. Its a lot of money for what i got im sure, but this is an ongoing project inwhich every little bit helps.

how do you think they'll do with what I have in the sig plus some AFR's? I already don't have much as far as bottom end goes.

I'd replace the hotcam with something more powerfull before spending money on a fast intake.

HMMM. What size should I go with then because Its an everyday car and I don't want it too raunchy. I heard that the AFR 205's are made for cams in the 224/224 range or so and a Hotcam aint much smaller. So your saying just forget the LSX setup?? Stick with the LS6 intake and ported TB??

Something in the 224 to low 230's range should do pretty good.

I respectfully disagree. The FAST 90 intake will give even the Hot Cam a gain of 10-12 rwhp over the LS6 intake with ported TB. Port the FAST runners (near the head) and you're looking at another 5-7 additional rwhp.
