90mm on the LS3 also. Supposedly the cathedral ports to this point made more power, but according to my buddy (who's the go-to guy in town, he's one of the smart ones) the new 260 rectangle port AFR's are going to be game changers. That's pretty much how he explained it to me.

Its all in the tune, a mechanic told me once that the Fast 102 was hard to tune on a procharged C5, that I had to get an LS6 intake, until I found the right tuner for it. Mine is great running 8-10 lbs of boost, everything is seated properly and sealed no problems, running with 90 mm LS2 tb.

We've been pushing 25+ through a FAST 102 for several years now. No issues at all.

I run LSA heads and LS3, make well over 1200hp. You don't need any expensive intake and I would rather spend the money on a better head to keep it together.

Yeah I'm not a fan of the 1000 dollar intakes anymore. Did a lot of research and asking around. However I did order the Holley Sniper with the 102mm, the guys at the shop that drag race said the 102mm throttle would be better for a boosted application, if NA then stick with a 92mm until you get over 800rwhp but even then the 102mm isn't really needed then either.

With your FAST, have you had to change from a drive by wire to drive by cable? All of the FAST, Holley and Atomic throttle bodies are drive by cable. I have yet to see them make a drive by wire. The only drive by wire throttle body that is a 102mm is the Nick Williams for a price more than the intake itself..
