This is an early Active Autowoerks kit, installed on the car back in 2004 we think. I got lucky and was introduced to another tuner that sourced this new Supercharger unit for me.
Trade off is the Rotrex units are not designed to be rebuilt. But if cared for properly should last 50-80k miles. We decided the old one failed a bit prematurely due to the bracket being bent.
Boost level depends on the model. This is a C30 and should be able to push up to 12-14psi. I'll be pushing about 7-8 psi on my set-up for now on a stock motor.
Boost comes on smooth in my set-up. The combination of the 3.2L motor with good low end torque and then the boost progressively feeding in just keeps you planted in your seat
