They are tit for tat, I have never been out powered by one. None of these engines were designed for 25+ hp, yea the animal and gx blocks are better metal and castings than the clone but they all suck and they all will blow just as quick as the other will and that is fact. My point is why spend an extra $250-$350 more for a little better block, then add an extra $100 to the billet crank made by the same company and made out of same material just to blow it up then guess what you got to spend that much more $ to redo it. When a motor is fixing to blow it's gonna blow no matter what crappy pressure washer block you put it in. The clone is superior in that regard and the power is tit for tat, if you think your animal is more powerful then my clone then so be it, a couple hp doesn't win the race, me and my tires do the job. To be totally honest with you I wouldn't mess with these pressure washer motors if the majority of open races around here would allow more 2 strokes and big 4 cycles. I'd much rather be piloting my 50+ hp sudam then a slow pos like an animal,clone, or gx200. Hmm....25hp maybe or 50hp......?
