Loughbd,
ASP'S and Magnum's run right along side of any other sport motor that I have seen. My .46XLS with a Tower muffler would wip the snaught out of a .46FX. My little Magnum .61RFS which I was talking about recently (low compression) runs like a watch a watch, and is actually getting better (compression) every day I run it. I am turning a 13-4W @ 10,000 on 10%. I am very happy with it. I will buy a ASP or Magnum any day over a OS of the same design and still have a pocket full of money. The engines you worked on years ago are not the same thing anymore. The Chinese have come along way. You have to get your head out of the dirt. THey have improved there quality drasticaly. For another example look at the Tower .75, it really performs.
