"I turned to CHR when I had exhausted all opportunities to raise the horsepower of my 2003 MINI Cooper S without performing internal engine modifications.

Jeff's plan included a massive horsepower and torque increase coupled with extreme durability even with a higher RPM limit. He prescribed a dual valve spring setup with titanium parts that would ensure reliability with my extreme track use as an instructor. For extra power, Jeff used oversized race-quality valves and some porting and polishing of the cylinder head, then matched everything to the intake and exhaust manifolds.

With 50,000 miles on my CHR Motorsports-modified engine, my car continues to perform on the track with the Porsches, BMWs, and Corvettes thanks to 240 WHP. My car easily outperforms the best that MINI currently offers."
