With some mods, the 700 EFI could *easily* make over 80hp. It would just take a little work. The motor is very similar in layout to some motorcycle engines making 65hp+ bone stock.

Hell if you wanted to, you could make over 100hp without turbo or nitrous, but that would result in real reliability problems, I think.

 

Any big bore can easily make 80 HP, its just no one puts in the R&D to see if they can or not.

 

Not true, the twin design has a lot more potential. I don't know about the Sportsman's plenum, it might be hard to make a lot of power with it. But I am damn sure that there is a lot of possibility in that motor.

 

I would bet rearwheel HP at a given rpm varies widely from machine to machine, there's too many variables in the clutch and the rest of the drivetrain. A few extra HP at the crank won't make much of a diffrence in the real world.

 

We did not recalibrate the 700 the owner did the mods himself and were and what he did I don't know. However he got good clean air througout the rpm range as we have an air fuel ration tool to measure this during a run.

Please note that it is not only the EFI making the 700 more powerful Polaris did go through three clutch designs since 03. The new one looks like a clamshell clutch on the driven clutch have not had one all the way apart to see but go to epi or partsland and look there is a difference in the efi clutch over a regular quad..

 

Yes and no... [img]i/expressions/face-icon-small-smile.gif[/img]

 

yes it has the team driven clutch on it
