My neighbor is building a quad from the ground up. He bought a banshee frame and is building it peice by peice for strikly sand drag racing at glamis this coming fall and winter. He just finished another Banshee mod quad but it's not so fast, he thinks he can get it to 75mph, I seen it go and it's not too fast for allthe mods. I don't think he put any engine building stuff on that one. The one he is building from the ground up he is putting a engine with 125hp he claims. I can't wait to see that run. My Honda Civic doesn't have that much HP. I'm a bit envious I would love to build a quad fron the ground up, would be pretty cool. I guess I'll hve to wait until this fall/winter at glamis too see it run.
