I have seen quite a few race cars with a piece of hose off the PCV valve and put a small filter on it. But remember these cars are not street cars and get a motor rebuilt often. In a new motor their is very little crankcase pressure and theirfore would be a loss of power to suck all the hot air in the motor from the crankcase, No oil would be entering the intake at all probobly. The guys that do run a PCV valve use it as a cheap vacuum pump. This aids the motors ring seal, personally i don't think that it would be enough to see a difference but that is what a couple racers sid to me.
