TVS Final Prototypes

[CFMINI]

Besides no S/C whine, another "problem" with the Rotrex is that you have to drive it like a sport bike - the best power and torque is from 5000 RPM and up to 8000. For a MINI that means you are always one gear lower than you would normally use. With an S/C MINI, it has that nearly flat torque curve from 3000-5000+ RPM so you can be in second, third, or fourth gear and get good pull coming out of corners. The Rotrex is better suited as a track car, or the Bonneville and Mojave Mile Events that I do.

That's why I have (2) R-53's - one S/C and one Rotrex. And maybe an F-56 turbo next year.
