what rpm is a stock 07 rhino engine turning ( with the factory cdi ) at max. speed (40 mph)? also if the stock cdi box is replaced with a hi-per unit would that let the eng. rev beyond the redline?

I dont remember the stock cdi rpm limit,but I have a dynatec cdi in my 07 rhino and it will not let it go past the red line. It does away with the reverse rev limit and that is good. I have a rais power tube and a 137.5 main jet (I am around 4200 feet elevation here in Utah) and a dial-a-jet in my 07 rhino and it has gotten as high as 50 MPH and I know there is more power to take it a few mph higher.
