If I'm reading that right, thats 302.1 at the wheels and 464.5 at the fly.......to me that seems a ridiculous amount of drive train loses for a scooby

:?

Its a Maha dyno Martyn so wheel figures are meaningless.
Clive Atthowes in Norwich was a similar set up and recorded mine with approx 40% tranny losses. Fly figures work out very close to DD or Dastek in the end.

So in reality its making a lot more power at the wheels than it say on the printout ?...... I always thought that all dynos measured power at the wheels, and that was the most 'dependable' figure ......flywheel figure's are open to debate, as dyno manufactures all seem to have there own way of working that out.
Just curious

Yes - wheel figures on Maha are rubbish but flywheel is accurate (as any other could be)

thanks for the constructive comments, mine isnt the most powerful out there on standard internals, and mine is only running 1.5bar.
