250HP out of a VW engine isn't going to last long, I don't care what any "expert" says. VW's have oil-cooling issues even at 100HP. A VW pumping out 250 is going to chew itself to pieces in no time at all. I've seen some VW-based club dragsters like PT is talking about, putting out that kind of power from a bored-out Type 4 engine with the euro pistons, but that literally was only for a few seconds at high RPM, and they practically had to rebuild the engine after every event. Putting out 250 for hours on end is a totally different animal.
