Rollmaster is the best

I had a notice in with my callies crank not to use the crank sproket with the 9 keways.They had some problems with the front of the crank because of them.

I would only use a gear drive in a full on race deal with sky high spring pressures.

Ive never personally had a harmonics issue under 8000RPM.



Uncle Dave

gear drives actually cost you H/P

The helical gear drives can, the straight cut ones dont, but they can be noisy.

Jackson claims no loss.

I knew a guy who installed a gear drive because he wanted people to think he had a blower under the hood... No joke...:lolhit:

P very common where i live to many bench top racers they read somthing put it in there car and they gain 100 hp from an air filter kinda funny. Alot of guys did that hear.

Don't care what jackson says...dyno says otherwise....NO real race engines will be found with a gear drive in a N/A app.

Cloyes Hex Adjust. Really easy to degree your cam and good quality.
