    MINI use along with most manufacturers the BHP figure at the flywheel before transmission loss.

    So does this mean that MINI quoted figure of 211bhp for Rocky would equate to roughly 183whp ?
    This is why I posted because I find it all VERY confusing.
    It makes me even confused now regarding PP’s original dyno figures !!!

    I just give up...

    From all of the above all that I can really work out is that Lohens dyno must so inaccurate that’s it just can’t be legal !!!

    Lohen figures are consistently larger they use a big conversion rate to go from the dyno to Bhp.

    If memory serves they use a conversion of 18% because they say that the minis have enormous drive train loss.

    My standard S with a decat ran 202bhp on their dyno

    For comparison after going stage 2 at 1320 my highest power figure was 232whp and the car felt like a rocket ship compared to what it drove in like

    It does Pete. You’ve got to watch with tuners as some will talk about power at the wheels and others at the fly.

    In my own personal opinion if people are selling goods ie: a tune or power mods for a car the dynos that they use should be tested by Trading Standards to make sure they are accurate and all working to the exact same scale.
