I do not know for sure. I think the dry sump was worth more than 50 hp but some of that came from the pan vacuum so you could get that back with a vacuum pump. I think I'm going to try a wet sump on here just to find out. The dry sump is a killer setup but it is a hassle on the dyno. Lots of lines to hook up and it takes time to prime everything and then drain it all when done.
