When you get that mother tuned up you're gonna crap yourself. It's just a great engine with power from one end to the other. Outstanding mileage and a barkin' pipe. I've gotten to the point where i don't want 2 of any engine, but now i'm getting another B5 with the version 2 mod. Nothing else makes sense for me. I still enjoy my other brands but the clocked B5 is the truggy king. Haven't tried one in buggy yet, but i will.
