Thats kind of what I was saying. It made more power due to loading but then I did a google of 4th gear clutch slippage and found a writeup under worldphaco.net. At first I thought this kind of shot my theory that the engine makes more power(works harder) in 4th or at least that that is the cause of the slippage. But this writeup uses the theory of CEP (constant engine power) which is not real world. The writer talks about when you accelerate but doing it with constant power. Without additional power how do you accelerate? Not sure his calculations are valid in the real world.
