Evo? If so, will all the units out there get plates or stickers for their units for vehicles in CA?

Hello, I just wanted to clarify a few things. The rev limit is set at about 6900 RPMS. We do this b/c with the centrifugal type of supercharger, they generate more boost as the RPM's climb. The difference between a 6900-RPM limit and 7200-RPM limit is about 1.5 PSI of additional boost. To keep things safe, we have lowered the rev limit to prevent the boost to go beyond 6 PSI total for safety and longevity. We could keep the rev limit at 7200 RPM's however we would have to increase the pulley size, thus lowering the max boost to 6 PSI. This increase in pulley size would reduce the low to mid range power. There is a trade off either way or we chose this route to give the best of both worlds. Hope this information helps.
