Rod may not see this, so I'll take the liberty of replying to this question......we put 90 passes and over 20 dyno pulls on the same crank, rods, pistons, bearings, rings, head gaskets, valves, springs, rocker arms.....in short, we didn't break anything in nearly three years of racing. Engine-wise, anyway.
We are putting rods and pistons in it now....we hate to spend the money, but there is a finite life for those components and we can't afford to find out what that lifespan really is!
The only components that have been replaced are the spark plugs and one fuel injector which was stuck open when we fired the engine the first time. No lie. Many will say that a 2800 hp engine is a maintenance nightmare, but it hasn't been for us so far. I can say for sure that our low engine speed (never more than 8000-8200) and the fact that we take care of the fuel system and keep an eye on injectors, the fuel pump, etc. makes a huge difference.
Every single pass we have made has been above 2000 hp, some were close to maxed out, others we had power pulled to try to go A to B. But I can say with 100% certainty that we have been 2000hp+ on every single hit. The first dyno pull was 2600 hp.
