Mark,
If a zed had 700bhp at the hubs, would we still add 35/40bhp or would it be more? (i.e. 10%).
What would make it lose more than 35/40HP? If the drive train is the same then the losses would be the same as the it requires the same force to move it. All this talk of percentages is madness. However, you could lose more in real terms if you had a beefed up drive train that zapped more power
That does sound like it could be right.
