This configuration offers significant opportunities for power; best thought about as "percentage improvements" starting from 115bhp and 110# torque. The CVT will accept more power; how much is a question we're still working on.

12/18/2003 Edit: I now believe this statement above to be incorrect based on new MINI and ZF Group information. The MINI CVT-equipped cars have been calibrated to accept 150Nm torque (110 ft-lb), which is the standard output of the Cooper.

I've done some limited investigations, but have not made any changes until we better understand how the CVT truly works.

What's fun about this power side of the equation is that big percentage changes should be possible relatively inexpensively.

There are several people doing headers. I've seen one (MINI-Madness) being independently tested, and the testor was surprised to see "significantly more than" 10hp gain. That's at least 9%!

A very free-flow Cat-back exhaust will augment this gain.

On the other side of the motor would be very-careful cold air induction.

Someone told me that once we get going, a reasonable, affordable target should be 130-135bhp. That's something like 17% more power, combined with the more balanced Cooper CVT, that should become a very entertaining machine at track days with the MC 5-speed and MCS 6-speed guys.
