<VV> Slightly OT Dog-Rings

And  don't forget double clutching! For those who have  unsynchroed
transmissions. Either by design or parts worn out! Anybody have  a dogbox in
a Corvair?  Frank DuVal




My Corvair powered Lola Autocross car had a Dog-Ring Clutch Hewland in it.  
I was told at the time that you could shift up by just releasing power and  
pulling it into gear and blipping the throttle to go down a gear. With many 
 (almost all) of my years using synchromesh transmissions, I had a devil of 
a  time trying to do this. It always seemed like trans abuse! The normal 
Hewland  was installed in formula cars with tiny multi-plate clutches, where 
you were not  allowed to slip them - Okay, you could do it once, then they 
were shot! My  Crown-converted Corvair to VW/Hewland set-up had a Kennedy 
Engineered Products  HD VW-style pressure plate and a dune buggy disk. You could 
slip that one all  day long! It made the car much easier to drive. I 
actually built the car with  two sets of high-low gears. The left side was 
low-high2nd - and the right side  was not-so-low - fourth. On slow courses I stayed 
on the left side - It would  still go 70+. On the right side, a slight 
tougher start, but not-so-low was good  from 25-50 in slower corners, and fourth 
was good for speeds I didn't want  to drive at! I never had to cross over 
the H in the shift pattern on course.  With the Hewland, you could put any 
gear in any shift position.  Handy!
