RZR Por R

I have a buddy that was out in AZ talking to a shop about the RZR and the difference between that engine and the Slingshot. According to them the only differences are the pistons and cams. The RZR has a compression ratio of 10.4:1 (but I thought it was higher than the sling) vs the Slingshot's 11.5:1. I do not know the differences in the cam grinds. Allegedly, the shop in AZ had a RZR Pro R that was making 500whp and they ran it full out on a chassis dyno for 40hrs and found "little to no bearing wear". Now all of this is 2nd hand info to me so take it for whatever its worth.

Here is a page listing the specs for it although it's not a Polaris page so some data may be wrong. https://www.utvdriver.com/stor…s/2022-polaris-rzr-pro-r/

I have their ATV on order and it has their ProStar 4-Stroke DOHC engine in it. It has been on order for 3 weeks now and they haven't started building it yet. This is only a 44hp engine but will do in the woods as this is flat land Florida.

Here is a link about the new motor - link

Edit - in the video they say its got a 12.5 to 1 compression ratio
