Here are the diff ratio's for you...
Diff ratio’s
Stock- 2.85:1
UE 1/8th - 3.31:1

and squee I've been running my 1920/8 ot the rpm range of 56433.6 RPM for over 4 years and I've never had a issue with it overheating or anything....for me to run it at 40,000 rpm I would only be able to run 8 cells and that's it...

Thanks for the ratios. Can you tell me the pinion and spur tooth count on those UE's? I want to add it to my speed calculator. To keep the precision as high as possible I don't round answers at all until the final output.

The ue has 43 on the spur with 13 on the pinion.
The hb pro gears are 43 on spur 10 on pinion.

Would the hb work well with a 7xl or 8xl motor..!!! and what kinda speed..??

Thanks CHC. I've added those diff ratios to my speed calculator and uploaded it.

I just realized that if you use the HB Pro diff along with a typical spur/pinion, you almost don't need a tranny, especially if you set the spur/pinion up right...

That may be...But the Feigao's and Wanderers aren't as high quality and aren't rated for so many rpm's. The bearings will fail easily. And yes, jhautz is right. 45K would be good for something like a Lehner, but I would perfer to keep it around 40k. It would run cooler, draw less amps, ect.
