HELIX MINISPORTS / P&D PULLEY INSTALLATION PICTURES
On March 7, 2003, I stopped by Helix MINISports for the installation of a 15% smaller pulley for the supercharger on my 2002 MINI Cooper S. It took just a few hours and you can really feel the increase in power across the whole range of RPMs. I highly recommend it! Check out all of the pictures here. This modification provides a gain of approximately 13.7 hp at the wheels (16.12 at the crank) and 14.6 ft. lbs. of torque at the wheels (17.18 at the crank). That basically takes a car from stock 163 hp to modified 179 hp and 155 ft. lbs. torque stock to modified 172 ft. lbs. torque.
