Relative to performance this may/may not help, higher manifold pressure yields higher airflow velocity but also labors the charger more which creates added heat - its a function of the engine combination. My point is it is not directly indicative of power output. I am working on an application now that runs 8psi boost on the low power variant and 5 psi boost on the high power variant. Exact same supercharger system, drive ratio, etc - the only hardware difference is the cam profile. The low boost version makes 50Hp more.

A regulation on boost level would be no different then to limiting all NA applications to the factory rev limit (Nobody runs higher RPM than the OEM do they?)

If they did limit boost than it sounds like your goal would be to find the best cam and boost combo to make the car run fast with the limitations set. Why would this not be a great way of limiting these cars adn still being a competitive combo in the class? Boost does not necesarily have to be limited to factory, so there could still be room for performance gains.

SSDiv6,

Is there a thread on classracer that you don't pop into and know EVERYTHING about. Or talk like it.
