Thanks again for arranging the day Gibbo, and nice to meet everyone.
Looks like my spark angle went wacky and cost me some power...will be investigating that so good to know. My transmission loss should apparently have been about 24 hp higher.
Transmission loss is not fixed.
It changes depending on the speed
The higher the speed the higher the loss will be.
If I did a run in a different gear you'd have completely different loss figures.
A higher gear would give you a greater loss and a lower @ the wheel figure.
