Fast LSX 90/90 installed This is on a 408 motor. Also Nick Williams 90mm TB, which I must say is very nice! Machine work on it is beautiful!
Install was pretty smooth. I had an LS6 intake on the car. The difference feels night and day!!!! Thanks to Speed Inc for gettin this stuff to me in a timely manner!
Throttle response with this intake feels INSTANT, where the ls6 felt a little hesitant down low. I havent felt it up top yet. Finally my 408 can BREATH!!!
Although I dont have before dyno, I will post results soon.
Purdy?

i bet that lsx package makes a bigger difference on bigger cubes like yours than it would on stock cubes

ls1 motorsports lid? I forget, it doesnt say anything on it, a friend gave it to me when I did a turbo on his car.
Yeah the 90mm is only good on H/C or cubes. Otherwise, dont even waste money on a 78mm FAST...so I am told

What size lid, MAF, and bellow are you using? I was thinking of doing 85mm. Wasnt sure if that was what you were running or if you were running stock size. What bellow is that because it looks like the one I have but I dont see how it would fit on a 90mm throttle body. I'm still using the stock one, but its ported and polished. It doesnt have any affect on the outside of the inlet though.
