It sounds like Belleville

Midgets : Belleville High Banks

Sprints : Eldora Speedway

My observations are that it would be a track that you're constantly on and off the throttle, not one that you run flat out the whole lap. Most motors I've seen start to blow up get hurt initially due to the sudden RPM changes.

The ever changing stresses and harmonics with varying the engine RPM's is extremely hard on the rods, rollers, and piston wrist pin areas, not to mention the cam gear drive backlash lag on deceleration offering the valves an opportunity to kiss the piston a few times.

we're going to have to agree to disagree.

Cecil, I believe you are incorrect about your flat-foot theory. Stop and go is rougher on an engine than constant rpm. I would like to see an engine builder weigh in on this.

Winchester with wings. 180 mph twice a lap and incredable G's (suck the poop right out of you if your not careful) for winged sprints Have to duck down to see under the wing in 3/4 to see the turn. We get If we are lucky 10 shows out of a fresh on pavemwnt. I have friends that claim 30 show on dirt non wing. don't know anything about midgets cept they are small.

salem with a wing could probably hurt some motors as well

Salem is tough sucked an oil filter inside out there and killed the motor next show. But salem is too bumpy to flatfoot like winchester, especially turn 4. But tough indeed

I agree that the constant up and down on the throttle eats a motor more than RPM. It just the physics of it.
