A celebrated Vendor recently tossed in a couple of "Freebies" to repay a favor, namely these well-reputed Ramp Plates:
The Inside Story:
Now both plates are about the same diameter and effective height, but the clear differences in ramp angle as well as how far outward the rollers have to travel before the ramp plate adds its contribution to variator movement is obvious. Keep in mind that the movable drive face also has ramps - although curved.
I have yet to comparison test these - already had an SEF. My thinking is that the steeper SEF plate will leave the engine in a lower gear longer. I cannot help but wonder if the steepness of the ramps means that much heavier weights and/or higher RPM are required to get the variator to move all the way out.
Anyone with thoughts/observations/half-assed opinions may chime in here. This may be Stickied as a Technical Document, so be nice.
