Only way to know. Gunner Arlaud says it likes 8200 and they test I'd probably trust that over a machine but then it really comes down to your sled and your conditions, setup, etc. Quote Link to comment Share on other sites More sharing options...

At a certain point, more RPM equals more speed as long as there's still enough power on tap to overcome the various drag sources. 5 Quote Link to comment Share on other sites More sharing options...
krom Posted January 11 Share Posted January 11 (edited) 1 hour ago, Crnr2Crnr said: either the manual is wrong or the parts catalog is wrong... the spec sheet is wrong, and the parts book is correct, at least with what I've seen in the real world. As far as what rpm to shoot for, and dyno sheets, take a look at the time. Short pull = cold pipe = is going to make peak power at a lower rpm hot pipe = higher rpm for peak power Its not anything like it used to be before the ecus started using a pipe temp sensor, but it still happens. Haven't done anything with the catalyst, but every sled in the past used to like coming out a little low on rpm, then slide it up a couple hundred as the run goes on Edited January 11 by krom 2 Quote Link to comment Share on other sites More sharing options...

They are racing and need maximum acceleration also and more than anyone. You could argue they could load it down harder because they are on ice. The mountain guys are also running over 8k but hey I'm not arguing just throwing stuff out there Quote Link to comment Share on other sites More sharing options...
jonlafon1 Posted January 11 Share Posted January 11 The original post was saying he is hitting 8250-8300 with 66 miles on it.. That's to high IMO as it will gain a few RPM with more miles. Hell conditions alone can vary RPM by 300 easy.. If I was to guess Cat is to light in the primary AGAIN.. They have been for years.. Will see as more miles and testing/dyno possibly comes in..

Come up to the UP and see.. 600 can be held over 80+ for miles. I do not ride like that but it can be done easily. With Arctic blue for sure Edited January 11 by jonlafon1 Quote Link to comment Share on other sites More sharing options...

fortune46x Posted January 11 Share Posted January 11 8150 is the peak rpm for hp , I was always told to go slightly past peak hp rpm when clutching (I was told 100rpm over). 1 Quote Link to comment Share on other sites More sharing options...

I ran my last one around that. The difference was it wasn’t at peak until closer top speed and pulled its way up there. Now it’s screaming rpm way too early. I think that big spring is holding it back in the secondary. Gas mileage will probably increase as well with clutch work.

With Arctic blue for sure Held her down on this trail. Sled actually had about 120 miles on it when I held her down. I road 66 yesterday. I have had it out a few times. 1 Quote Link to comment Share on other sites More sharing options...

That is a long pull and a lot to make up if you clutched for 95-100mph and everyone else is running 105+ down the straights. 1 Quote Link to comment Share on other sites More sharing options...
