racing any motor that isnt warmed up to temperature leads to accelerated wear in the cylinder.
I have quite a few motors that were driven from a cold start or minimal warmup. The sides of the cylinders were the piston was pushed against by the rod or pulled down had been polished out and you couldnt see the hone marks anymore.
My car sees full operating temp (temp gauge in the middle) and my oil temp gauge has to read at least 30-50 degrees celsius before I start driving. My gearbox is really notchy when cold and when its idling in neutral, parts are still spinning in the gearbox, so getting it warmed up with a couple of slow shifts helps as well.
OMG ITS A NON-POLITICAL THREAD!! SOMEONE GET THE MEDIA!!!!
sorry but I couldnt resist...
