    I was led to believe the figures by mini were at the flywheel?

    It depends all depends on who is quoting the figures. Some use the fly figures, some use bhp figures instead.
    If my Roadster’s official MINI bhp of 211 was at the fly it would mean that it’s only actually got roughly 183 wbhp.
    The case of Petrol Ped above is a classic example.
    I knew something was wrong as soon as he said that his standard Roadster had hit 238bhp.
    Once I looked at the figures it then dawned on me why he’d “gained” 27bhp over the last 5 years.
    If MINI did use fbhp figures how on Earth did PP’s Roadster gain 53 bhp over the years ?

    Can't answer that, what I can say is my R55 JCW made 226 at the fly at SOS in Falkirk with a bigger Intercooler and sport cat downpipe.... Can't really comment on lohens figures, however cant see why they would fabricate numbers...?

    LOHEN aren’t fabricating their figures, they are just using one set of figures against another to suck people in.
    The difference between fly and wheel bhp is an average of 15%.
    If your 226 is at the fly that indicates that it’ll be around 196wbhp which seems low.
    Are you sure they quoted fbhp and not wbhp Craig ?

    Yep, as other figures for other cars were correct based on numbers and expectations

    I’ve just found that bhp is normally the fly reading and wbhp is at the wheels.
    MINI must use the wbhp figures in their official specs. There is no other explanation for how PP gained so much on a standard car from its officially quoted figures.

    My car must be seriously fecked then.... As if its supposed to be making 218bhp from factory and had those mods and a remap, should be about 230bhp anyway at the wheels.... And its only showing 226 at the fly..

    Honestly Craig the only explanation I can see to explain that is they must’ve used the incorrect figures.
    If you only had 196 wbhp I’m positive that you’d notice the lack of ooomph.

    Nope they were definately posting flywheel figures... That is why I believe mini quote flywheel figures as R53's were consistently showing around the 165/170 bhp on the RR.
