Technical winters quick change

anyone here that changed from strait cut to helical gear in the reared.. and how big is the different?

 

I haven't - but - there is a good thread on here - search for Quickchange on here...

 

Nope, still straight.
Part of the allure.

I remember Ronnie Roadster here on the HAMB going to York Nationals with straight cut gears in his Ardun Deuce and coming home to CT with helical cut gears. He said the difference was well worth the change noise wise in an open car.

 

I have run both straight, and helical gears in V 8 and Champ QC's. I always run helical on the street. Still get some whine at around 30 mph, but NOTHING like straight cut gears. Always used straight cut gears drag racing. It takes a little more power to pull helical gears.

 

I switched to helical gears in my winters V8 quickchange and it's as quiet as a 9", what a difference!
If you switch be sure to get a spacer and shim kit with your new gears.
Straight cut gears are self centering, helical gears have side loads and require shims

 

All of the above is correct. I have found that later straight cut gears tend to be quieter than older ones. Also, there are better (more expensive) gears.
But helicals are quieter than good straight cuts. Limiting the end play is critical. I made splined spacers from old drive shaft couplers before Winters came out with the spacers. If you do it this way, you can set it exactly where you want it.

 

I bought a winters QC for my 29 with straight cut gears , haven't had time to change out the 9" yet but I'm looking forward to the whine
