Here's a few questions, do you think that a gearbox/drivetrain saps a set amount of power or a percentage of the power made? Does a gearbox/drivetrain loss measured during coasting down equal the same loss made under acceleration?
I dunno, you tell us you're the expert!
Regal were on about coasitng down through the rev range as it varies through... but 90bhp transmission loses? Laughable.
Robin, JKM was 318.2bhp (but Jim admits that if I allow for this and that I'd get a different result...) So I paid my £35 for what, not a true result thats for sure... And just paid another £30 for an equally laughable result...
The only thing I'm happy with is at the wheels figure(290bhp), as comparing to loads more graphs on here which have fly/wheel figures, represents approx 340-345bhp, which would be around what I expected.
