So say you got a 400 horse motor that you want to run 5 psi at, say your getting a 25% hp gain out of that 5 psi your hitting 500 horse now. Atmospheric pressure is 1 bar (14.7psi), so if you were to run 14.7 psi of boost you would have twice as much pressure in the chamber as compared to no boost, therefore your hp gain would be doubled. 400 horse turns into 800..
Thats why the most common psi used in boosting is 7-8, at 7-8 your getting a 50%+hp gain on a good build. At least thats how all my prior experiences in the past have been with import motors.
Nevermind. You need to stick to Honda's. Leave the TT383 to those of us with the smarts. VTEC rulez!
