Twin screw blowers do generate a good amount of heat. Anything over 8 PSI you will need to look into water injection. The M45 really can only take around 11-14 psi, after that it is spinning way too fast for its own good, or at least that is what I have heard from BRP. The MP62, however apparently can spin up to around 20,000+ rpm, according to Eaton, and Big Gulp. I would be curious to see someone put the MP62 on a b series, as it is the perfect blower for our cars. I have seen miatas make around 340RWHP with an MP62!!! Now imagine that set up on a Honda motor that has a much better flowing head, the numbers I bet would be close to 400WHP! Of course that would need to be intercooled. It would be nice if Jackson Racing made a new manifold that could be intercooled, much like what Flyin' Miata is doing with the Uber Charger. Fuck, HASport should be making an Intercooler compatible manifold for the JRSC kit. I would consider getting a JRSC if I could get an intercooler for it..
