I was just looking at some of the runs that they had on there and they are done by MPH instead of RPM. That is weird most of the time it is done by RPM, but most of thier runs are on automatic quads so it might not be very acurate because it would get up to the shifting point and stay at the same RPM for a long time. My question is: do you read the chart the same way as an RPM chart or how do you read them? They show the Rancher AT stock having aroud 13.7 HP, the Forman 450 having 12.2 HP stock, and the Rincon having 21.4 stock. Those numbers look kind of low even though they are more tuned for torque TexMudder's sight has the Rubicon at having 20.9 stock. Which ones shoud you belive more? Beats me!
