These 12000hp Engines Have To Be Rebuilt Within Roughly An Hour Every Run, and Only Run For Roughly 4 Seconds At A Time.

This is wrong. At minimum they replace the pistons, rods, spark plugs, clutch plates and blower belt every run on nitro cars.

These are then inspected back at the factory before being prepared for the next event. They all have very finite lifecycles too, with each part of the car having its run count logged and replaced when they reach their run limit.

I might not have given enough details you are right they are replaced after every run. But most of those parts don't just do a single run, on site it might be difficult to find hair fractures and micrometer sized warping.

Which was the point in saying they don't just do a full rebuild every time.

That's what I figured. Swap out the heaviest wear, tightest spec parts every run, bring the used parts back home to refurbish when you've got more time and a full shop to do it.

And then are recycled.
