What about this bullseye power. Looks like a good deal but what horse power is it rated too?
but Midwest has an excellent rep and Chris and his wife were an absolute pleasure to deal with. Returned every phone call that day. Took a little longer than the promised lead time but that was because they were moving shops, which I was aware of, and they upgraded the billet wheel that I ordered to a new one that dyno'd another 150hp, consulting me by phone first of course.
