Dragzine’s Andrew Wolf recently interview Neal Chance about our new PowerPump, a new improvement in the efficiency of fluid transfer.

Marty Chance said – “Positive pump angle in a torque converter is like base in a clutch. It’s what really drives the tire. So the more positive pump fin angle you have, the more power transfer potential you have. We designed a pump impeller that can give you more base, like in a clutch, with even less positive angle. We made it become more efficient, sooner, which results in an increase in power transfer potential. It goes far beyond fin angle, and gets into the science of power transfer. A torque converter, by definition, is a hydraulic power transfer — you’re just transferring power from the crankshaft to the tires, and you’re doing it not with a solid coupling like a clutch or a lockup converter, but only by transferring fluid. We’ve designed a better mousetrap that does this more efficiently. For something that used to require a factor of 35 of base to transfer X amount of torque, we can now transfer even more with a factor of only 30, for example. It’s a better transfer.”
There are very limited quantities right now of the PowerPump. Full production won’t begin until February.
