What intake is everyone running with big boost?
We swapped out the LS2 intake on this engine for a FAST 92, we lost boost but rwhp went up from 809 to 864! http://www.exoticperformanceplus.com...Car.php?car=29 Bob
This is pretty much the results I would of expected. I hate it when people say you don't need a good flowing intake or heads, that you can just turn up the boost. Well yes that is true you can turn up the boost and make more power but just look at these results and if you have a good flowing intake and heads and turn the boost up, you get way more power
Slightly off topic but I wonder how much larger the CSA (cross sectional area) on the FAST intake compared to the LS2/6 intakes? For that matter, wonder what the difference in Taper, Plenum volume, and runner length?
Anyone know?

I really dont know. If thats a legit 50+hp gain from nothing more than the intake, I'm definitely gonna reconsider getting a FAST.. 
I have helped a number of forced induction cars with my ported FAST manifolds (some of them approaching 20 PSI).....most of them producing extremely good power.
If it works well N/A its certain to work under boosted conditions as well. The only difference is a higher pressure drop from your TB to your cylinder heads combustion chamber. Boost is no different than REALLY good air if you think about. A more dense charge under higher pressure but unlike altitude changes it is created mechanically. The negative of the mechanical situation is added heat making the air less dense but thats easily remedied by the intercooler.
A good exhaust system (and exhaust port for that matter as well) can add to that on the upside because ultimately a blower engines main strangle point is not being able to clean/evacuate the cylinder completely for the next induction charge....once that's compromised power starts to fall off shortly after.
Good stuff....

PS....And the runner cross section and taper of the FAST is far more conducive to making power.....night and day difference from even a stock manifold regardless of what digit falls in front of the "LS" designation.
