I think they make around 130hp, Peak is at 7200 rpm.

I'm going off the top of me head, can someone correct me if I'm wrong

TD is the MAN!

So I guess I'm over revving, my sled Reeves around 7900-8000....what's your rpm's, DT gave me a set-up that I'm going to use for 660ft snow drags as soon as I find out what I have in it now for clutching. the first thing I got too do is get a clutch puller and see what's in there, the guy that I got the sled from said it was all stock..and I don't have a clue what the stock clutching is.

7700 -8000 rpm is the HO's sweet spot. I don't know where the quote of peak power at 7200 came from.

7200 would be 521 and 582s shift rpm(583 without Rave)


most Doo rotarys with Rave are 7800 max
