Blowing up motors is all about what you do with them.
You can use the best parts, the best builders, do it yourself, check and double check everything and STILL, shit happens.
You can build them to 400 rwhp and you can build them to 800 rwhp and everywhere in between.
If your car is a dyno queen, a garage queen, a keyboard racer, then you probably won't be blowing up any motors any time soon unless you have a bad tuner.
If you track your car hard, hit the 7800 rpm range, brake hard, heel toe and on the gas coming out of corners back to 7800 rpm hitting apexes as you go and hitting 150+ down the straights, then chances are your going to cook a motor sooner or later.
Those are the facts. No way around it. If anyone thinks otherwise, please by all means tell me your secrets.
HP cost money and with it comes the frequent chance of failure, that's the way it is.
The faster you go, the faster shit breaks.
