Also, transmission fluid takes longer to warm up still and we all know how strong our 5mts are. It's dumb to see significant amounts of boost/engine load for the first couple minutes

Wouldn't be surprised if a significant amount of bearing failures are in part due to people running the piss out of their cold, old blocks, which could cause shear and stress on the bearings and when they really spin, could be well after the engine has warmed-up and the warm-up factor is not even considered. Then again I'm not a fan of the 2.0.
