Power or PSI?

[jdkatz]

Hey,
I'm pretty good with cars but just wanted to know that if I upgraded say the intake manifold and throttle body. Will that let me make more power at the same psi as before, or will it raise the psi i run at??

The only thing that will raise boost is a boost controller sometimes openeing up the exhaust can cause boost creep but changing the IM and TB will not.

to answer the question, yes it will make more power at the same psi

Given a constant PSI.. you can gain HP by freeing up the intake/exhaust tract just like on an NA car. As L2R warns.. to little restriction in the exhaust can have the side-effect of raising boost.

As an FYI.. the TB / Intake manifold upgrade is wayyy down on the list of typical DSM mods behind exhaust, boost controller, upgraded intercooler/plumbing, injectors.. even turbo.

thanks for all the info and i know that is down on the list. I just wanted to theoretically know what would happen. Thanks again.
