just because something is working good doesnt make it better.
How many 7 bolt heads have made 1500hp?
These other 650hp+ evos that run slower than Curt (I would bet) are not nearly as light nor can drive as good as Curt.

I dont really think the likes of John Shepherd, Brent Rau, Curt Brown, Marco,TY, Kiggly, DG and so on are idiots. They are probably the farthest thing from idiots.
