Intake manifold?

Ok guys let me tell you what im running at the current moment. K&N Dual Intake, west coast vette MASS air flow sensor, west coast vette air duct and coupler, throttle body coolant bypass kit, 160 thermostat, corsa pace car exhaust, diablo tuned..now i want to add an intake manifold I am thinking the FAST LSX manifold, does anyone know for sure how good these things are?..do they add a good amount of hp?..I am also going to use the West coast corvette throttle body on it, do I need to get bigger injectors or fuel rails?..and does this steal any of my low end torque, I dont want to lose any low end power i love having it and dont want to lose it. let me know what all you guys think I appreciate it thanks!!!!

The manifold, absent other mods, will make something like 5 to at most 12 additional horsepower.

I couldn't imagine you losing low end torque/hp. I would imagine that it would be an increase all across the board. I could be wrong though.

larger runners kill low end but help on top

With your present mods it will be a waste of $$ to buy a FAST intake..go with a LS6 intake..they are good for a little over 600 HP.

Yes...the FAST works well with mod engines e.g cams with a large lift, head with good air flow..where as the LS6 works very well with small mods to stock engines. A FAST that is ported greatly benifits big modded engines.
A used LS6 can be bought for about $350 and will give a SOTP and some HP gains. Othres witll chime in. My $.02
