Ok, so NASCAR mandates a reduction in engine size, say from the current 5.86L down to 4.8L. Bore and stroke dimensions will be reduced, this will reduce horsepower, but shorter stroke engines can usually reach higher RPMs than longer stroke engines. I don't think horsepower is what is leading to drivetrain failure, I think it is the very high RPMs to which the drivetrain is subjected.
Can NASCAR become the same as IROC, yes, they certainly can and I expect they will have the same fan base as IROC. Where is IROC today? It's gone.
And by the way, are we really seeing a higher incidence of equipment failure?
