With an 18% power loss through transmission drag you would run a wheel figure of 362.85bhp.

That is still an awesome wheel horsepower figure and flywheel figure though.


Unless the Rolling road operator has got confused and that graph is the wheel figure like on most rolling roads. Ie they worked out that figure to be the wheel figure off the flywheel. the graph states otherwise though

sh*t! - Sorry Rob/Pukka - That's a good point - I'll check, but it was Thor themselves (Peter and Lyndon) who worked out it had just made 520bhp (Same when it made 419 on the last graph - Lyndon had pointed out that the figure was from the wheels - then told me that that equated to just shy of 490bhp at the Flywheel) - It may be the "fly" heading is wrong - Forgot about that, but I'll check with the guys - It was a hub dyno though, if that makes a difference on why the heading says Flywheel?

The calculation was me adding the 18% back (I see the confusion given that heading), but I'm 100% certain that although the top heading does indeed say "Flywheel", the figure was measured from the hubs, as it's where the measuring equipment was attached! - Hence they had a known figure at the wheels, then added the loss back in to get the verbally quoted Flywheel figure...

Hope that helps - I'll double check with Thor tomorrow, as my rep's at stake , but I already know the answer...


Come to think of it, I reckon the true test will be to take Pukka (as he's a kosher unbiased kind of guy ) out in the ol' beast, drop the clutch, and get some proper feedback regarding how many horses he reckons she has!
