Cranky;

Do not really know the answer,but about 7 or 8 years ago back in my dirt track days,a local drag racer friend told me he thought we put as much if not more wear on our engine in one night of racing as he did in a 6 month season of drag racing every other saturday night......

On a saturday nite at the dirt track the motor probably ran for about 45 to 60 minutes at speed on the track.......

I would think the road race engine would see more punishment,at least I know mine does,on and off the gas from 3000 to 6000 rpms 10 to 14 times per lap,15 lap sessions,three to five sessoins a day,gotta be hard on an enigne............
