Today I took the CSi for the run on the dyno, and test results after the third run with a little enrichment of the system were: Max power 167.8 SAE horsepower, and Max torque 192.7 These results were at the rear wheel and they tell me, that is about a 15% loss. The engine ran strong and went up to red line without a hitch. The horsepower seems in line with the US model engine of the car (86 735i), but the torque was really good. Next time I'll have it tuned with new air filter and so on and that should give more horses.
