In the 140hp 2.2 ecotec engine, the balance shaft is suspected to rob up to 12hp at 5krpm. Extrapolating downward, and assuming the drag increase is square to increase in speed, that would be about 3hp (2.2kw) at 2500rpm, no? I think I did that wrong anyway... Never was good with that stuff. However, when you've only got 52hp, each one, IMO, is worth fighting over.

12hp to a 140hp ecotec is only ~10 percent of the total package... To a 52hp motor, it's ~20 percent.. Def more substantial.

That means that at 5krpm, not that the engine can get there yet, I could be using 20% of the engine's potential _just to spin a shaft, which doesn't serve a valid function anyway!_
