Novak 'L' motors..what differences will I feel?

[c0sie]

For example..if I ordered a 5.5R and a 5.5L and raced them back to back..same cells..same gearing..same tyres etc etc..what differences would I notice in efficiency, temperature and feel whilst driving in a 4WD car?

I would presume that the bottom end of an L is lot tamer than an R? Making it better for low grip conditions where you are still required to have alot of speed??
