Your "babble" is another bench racer with a slow car talking out your ass so I could care less. Yes my old ladys BMW would show you tail lights.
Yeah you know those asain woman there all fat huh.....

my slow car keeps me happy. yes i do have an ls6 intake.
ill listen to the gods as you call it from tech any day, thier cars are running single digits. im at the track somewhat often, no bench racing here

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.
