Try contacting ImportBuilders, JG Engine Dynamics, Portflow, or some advertisers on the board. They can tell you exactly what to expect.

Flow is a compilation of things, however, like valve size, etc... Decide on a setup, or ask them for advice.

it depends a lot on the mods you have on the car..and the motor...too much air flow can also be bad...you would be losing a lot of tq and your car would actually be slower
