Yea that is true. But that is also true of lots of engines. I've seen NA builds go boom from those same reasons. But most of those things can be prevented. Don't let your meth tank get low...don't push it hard on a hot day, leave your rev limiter on for just in case you do miss a gear. As far as bad gas, at best, you can use octane booster every few fill ups. But there is always some risk associated with these builds. I don't think the 2V engine is as weak as most people say it is. Can it handle 12 psi and 500 hp to the wheels? Well some have claimed to do it...but I think 400-450 at 8-10 psi is about what it can handle. By comparison, even the Coyote engines shouldn't be pushed past 10 psi absolute max. And depending on the size of the blower or turbo, you shouldn't even go that high. But for an engine that makes 260 hp at the crank to make 400-450 to the wheels is very good. That is identical to a S550 Coyote going from 430 at the crank to 570-620 at the wheels. Comparatively, the 2V is just as good.
