Go on then, say it. You know you want to. lol
The only problem with that is it's quite a difference in % to get those 2 rwhp figures in terms of trans loss.

I think it is closer to 20%, but of course it depends on the type of dyno. Fyi 20% loss is what is used for 44/68s for Porsche club rules here in oz when calculating weight/power ratios for classing cars.
