It's simply done by calculating the airflow based on engine capacity, compressor efficiency, intercooler efficiency and engine volumetric efficiency. From the air flow you can work out the horsepower using the air fuel ratio and brake specific fuel consumption. There is a lot of guess work but it shows which claims are bollocks! The above 237hp is without NOS by the way. The engine had 234 and they added a correction to it for some reason, giving 244. I don't think the correction should have been used but I wasn't there for the test so don't know what they corrected for (out of temp/humidity/baro). It was done on an engine dyno and by a reputable mini tuner. Cheers Daniel First 5-port EFI turbo in the world (built 1997, running in 1998) |

also with engine dyno figures are flywheel figures and no clutch is involved , is drive straight from flywheel to dyno
