Do you read Mini World etc??? They frequently run "dyno days" that report on outputs etc... Cheers, Ian |

Depends a lot on the dyno, the drive-on ones are all different. Good for pub points comparo on the day, but hard to compare to others, or even the same dyno at a later date. Lots of variables. We found 8HP in a race Mini by swapping the sticky rubber for hard crappy road tyres. |

Might have, until the 1st corner... ![]() Like I said ^^ good only for pub points. Or engine tuning. On the other hand, a `water brake' engine dyno has few variables, and is far more sensitive to minor tuning changes. So better for engine development. |
