All of the before and after graphs I have seen, have shown substantial gains with the FAST 90/90. Ported FAST gains have been even greater.
These were all cars with a cam or cam and heads. I have never seen before and after graphs of a bolt-on car with a 90/90.

I guess I'm one of the ls1tech, what ever you want to call us.
Basically, the FAST 78 is not really any gains over the LS6 intake. I have a Ported FAST 78 on my car & am ready to go up to a 90/90 set up ported by Tony Mamo. With a cam only car you will see some gains. The real gains come in with a H/C car. Your heads will limit what the 90/90 can provide for you. With a bolt on car i would stick with an LS6 intake. Add a Cam 90/90 will help. I would not put a 78mm tb on a FAST 90.

So when would you guys suggest a 70 vs a 90? I'm going to have some bolt ones but once I get the money I'll get heads and cam. i wouldnt buy the FAST manifold unless i had the heads/cam at the same time im just curious as to what application youd need a 90mm for or what kind of HP numbers

I wouldnt buy one untill you get heads.cam put on-if you do you will be just pulling it back off and like they mentioned its not worth fooling with without heads/cam.
