Default Anyone have actual data comparing a FAST 78 to a FAST 90

I'm looking for actual data (dyno sheet or track times) comparing a FAST 78MM intake and a FAST 90 with as similar setup as possible. I know the TB and intake tubes and MAF will be different but as close as possible would be great. Say the same engine mods (heads, cam,etc). I've tried searching here and the net as a whole and haven't really come up with anything. Thanks.

that's pretty interesting. I have been wondering the same thing...do I REALLY need a 90mm TB and intake with my setup? I've seen flow #s for the 78 vs. 90....that really doesn't mean much to me, of course the 90 will flow higher.

thanks for the info radkon.

does anyone have more info on 78 vs 90?
