Fast 92 vs LS6
Fast 92 vs LS6 GM HiTech Performance mag tested a new FAST 92mm/FAST 92mm TB vs LS6/Stock TB. The before numbers were 390/369, with the 92mm it made 411/382. The graph shows them equal to about 3700 rpm, then it starts gaining. This LS1 peaked at about 6250 RPM, it had a 225/229 cam, not sure of other mods. It was retuned after the install.
Yeah.. "good" power.. 20hp. GM Hightech priced the TB and intake at $1400.00 Man.. for another $250.00 I can buy a Riding mower with 3 more hp.

Some people always looks at mods as a individual $$$ per HP ratio.
Its the overall combo that matters most.
That intake is going to make power and support alot of power for future mods and is x-ferable to almost any setup short of needing a sheetmetal intake. Personally I am a person who builds a car from the rear end forward. So I would be looking at suspension and a 12 bolt/9" setup.

Those are definitely impressive gains.

Yea, was a lot of money (even more if you include porting), but my rational was that it allowed me to make the same power as some of the guys with those huge cams, but still retain drivability. It certaintly isn't the first thing I would have done though.
BTW +1 on the 9" setup.

Me too!! well 90/90.... At 3700rpm and up it looks like it will help me out. My stall will put me right where i can start taking advantage of it
For some reason I thought the real advantage of the fAST didn't come in til later but this is good to know. I ws looking for that old post with the overlayed graphs that showed a FAST90, LS6, LS1 and maybe one other against each other but couldn't find it.
