Here is our results for a good baseline of the RZR and the RZRS in stock form no modifications were done to it, we will be testing later next week with a modified RZRS running a 860cc Big Bore with a new cam combo and the +2 Head ported, polished, flowed, we also intend on changing a few other things to see if there are any gains? Stay tuned for the upcoming dyno’s to put some facts out front, of what works and what is hype, as you can see from the other dyno’s our Big bore puts out some real numbers and guaranteed that your butt dyno can feel the difference, we will be offering a complete big bore kit with a custom cam setup, fuel and ignition system dyno tested and you get the numbers that you pay for, keep checking back and we will be posting the results, you can also check out our web site ricochetracing.com we are now offering turbo parts and accessories take a peek!

That was a mess up on that run.... Minibusa should've labled the runs rzr and rzr s so we could see which runs belong to which car.

dragged my friend with S and I have standard. No clear difference. The S header pipe probrably gives that extra gain.

I think he is doing the stock testing to show that the dyno he is using is accurate. So when he does any thing more on it ... he has a good base line.

I know Ricochet Racing has some Big Bore kits he is working on ... with some great numbers being posted in other thread! He got some good number on motors with barrel/head changes ... cant wait to see what is in the works. The results of his testung will definitely be dictating what motor I go with next year!!

Im taking it as a 8HP difference. If you read the description closely. It looks like the 2nd graph is the best run of rzr standard with 3 runs of a rzr S overlayed.

I think the factory spec'd 7 HP gain on the S and that is about what we are seeing give or take a little.

also you have to think about the S weighing more(roll cage, long travel, bighorns) then the stock and i have never been beat by a stock one, when my S is completely stock. Not to mention if u have stock one with the little tires on it, tires make a big difference on how tall they are in speed and acceleration.
