[Tigers] Dana 44 Question

[Buck Trippel]

Larry has a good question and Theo came up with a quick answer that is very 
interesting. I had no idea the number would be so large. Thanks!

About ten years ago, Trevor Harris urged me to concentrate more about how 
much torque the tire patch can absorb. Once that's exceeded any excess 
torque becomes almost meaningless.

BTW, there's a great article in the new (nov/dec) edition of Vintage 
Motorsport about Trevor. It's about 8 pages long & is titled "Racing's 
Unsung Genius". I can't figure out where they came up with "unsung". After 
all his CanAm cars,
Gurney Eagles, BRE, Electromotive, and 30 years at Indy, I thought he was 
pretty well known. And that's without the off road Trophy trucks.
