Those are my numbers as of February 27, 2006. I'm less than impressed with these results. MINI factory specs for the 2003 Cooper (non-s) is 115hp @ 6000RPM and 110ft.-lb. torque @ 4500RPM. Their numbers are recorded at the crank, and the dyno runs I did are measured at the wheels. A 15% to 20% loss can be attributed to the drivetrain. Even so, if you factor in 20% to my numbers, it still isn't anything to write home about. However, something else to consider is the MINI specs are most likey run using 93 octane fuel, as that is what the ECU is programed for from the factory. My dyno was run using 91 octane, as that is what we have here in California and that is what my MTH ECU file was tuned for at the time of this dyno.

My dyno numbers inspired me to experiment with 100 octane fuel. My ECU program from MTH allows for free remaps for 12 months. Volker at MTH had my new file in under two weeks. With 1496 miles on 100 octane & the ECU remap, I dyno'd again on April 10, 2006. There were improvements, but +3HP & +3.6ft.-lbs. torque is hardly worth $6.20 a gallon for a daily driven street car. Results below:
Too expensive for the likes of me, but it was fun while it lasted. I actually had Volker make me a 95 octane file too, but I'm not even going to bother with that. I want to get back on 91 octane.
Below are pics from the February dyno:
Douggie taking a peek. I went to DRS with my buddy Doug who got his 2005 Audi A3 dyno'd the same day. Check that out HERE.
