i know i sound stupid for asking this question, but what is a fluid drive, i know what a cvt belt and all that is , but what is a fluid drive, and how does it work,and what is a rubber variable lift camshaft and how does it work. thank you for your time to ne one who answers

 

I would to see Polaris come out w/ a v-twin in their ATVs. I just think that w/all the years the parallel twins have been out, for Polaris to switch to a V-twin design now is unlikely. I'd loved to see a scaled down liquid cooled version of the freedom v-twin Polaris puts in their Victory motorcycles in an ATV.

 

The fluid drive I believe is kind of a hydrostatic type drive. I have no idea what the variable camshaft thing is, although I do now that several car OEMs use variable-valve timing, although I don't know exactly how it works.

 

o ok,thankz kuvie, well i just looked up fluid drive and understand it know, but i can't find ne thing on the camshaft and how it works

 

Djk,
The rubber camshaft thing is a joke, been around since the internal combustion engine was invented. If it worked it would be great, but it won't, at least with the rubber we have available to work with. [img]i/expressions/face-icon-small-smile.gif[/img]
A V cylinder configuration or inline configuration doesn't make any difference to power output, everything else being equal. It is for packaging usually, or because some people mistakenly think it makes a difference and would be more likely to buy it. Like Harleys... 88 cuin V twins that make less power than a parallel twin 650 (40 cuin) Kawasaki Ninja. But most Harley owners think otherwise. LOL
Kawasaki's V twin 650 and 750 ATV's are powerful, but it is not because they are V's.

 

o ok, thankz for inlightening me nekk

 

I was comparing the Liberty Twin to the V-twins of Can-Am, Kawasaki, and Arctic Cat.

At 55.4 hp, the Can-Am 650cc makes 5.3 more hp than the Polaris 800. Why? I'll bet is has something to do with cylinder configuration, a shorter stroke, overhead cam, more valves, higher compression ratio, and higher redline. Which brings me back to my claim that Polaris cannot do much more with the Liberty Twin to compete with current V-twins, except to add a turbo or supercharger.

 

Are you saying the Polaris is 55.4 hp and the Can-Am is 60.7 hp?

 

I want a 4X4 Outlaw under 500 pounds. That would rock! A 4x4 sport to compete with the Renegade.

 

The polaris 800 is 55 hp for 2008 and about 51hp for 2005 to 2007
