Take top fuel dragsters for instance, they run nitromethane and they get rebuilt after everyrace

thats high performance fuel.
Well thats not quite the same thing. I dont really think that running 30% will drastically shorten the engine's life, now I can see where people get this from, but when it comes down to it, I just dont see it really shortening the life of the engine. But the point that me and dann are here saying is that you can do other things here to gain that power and have that power all the time without spending $200 (or less if dude7422 every makes his).
It's just not worth the time and hassle to do all of this when you can just get a new engine or to get 30% fuel instead of 20% nitro. A new tuned pipe ot maybe a moded engine, or other thing's. There's just so much more you can do to get that power for the entire time that your running instead of the 8 seconds of power.
