Does anyone know the low and overdrive ratios of the polaris P-90 model Continuously variable belt transmission?? I cant pry it out of Polaris themselves and the dealers wont make the call for me. Thanks!

Depends on your springs, weights, belt width, helix, buttons, and secondary springs..... Tons of variables. What exactly do you need the ratio for?

Im asking for the ratio range actually... whats the lowest it can go, and whats the highest it goes. All of those variables that you described change how it shifts in the range. The sheaves (or cones) diameters will determine the ratio range, and unfortunately I dont have one on hand to measure.
As for the application, I am trying to find a CVT that would work well on our Mini Baja car for the upcoming season.

Looks like 3.8:1-1:1

Good info here. (http://www.snowtechmagazine.com/articles/clutch/cltchtun.html)
