Has anyone tried Twistgear made by Johnson Engineering in Iowa? In a previous thread regarding final gearing ratio change, several years ago a few members have mentioned this product, but there was not much discussion on it. In an attempt to re-examine my final gearing, I visited
www.twistgear.net as an option to consider. The site is very comprehensive and informative.
Main items which replace stock are trapdoor bearings, a more robust countershaft, helical main gear and helical fifth gear.
Supposedly, TwistGear provides 10% more gear box, which can be used several ways. If you only install TwistGear, then 1st through 4th will go 10% slower but with 10% more acceleration than current setup. 5th gear rpms will stay the same. Adding one tooth to the transmission pulley, gives 7% more torque in 1st-4th but 5th gear rpms will be reduced 3%. For top end speed/low cruising rpms, change the final drive or primary drive ratios 10% so that 1st-4th stays the same as current setup but 5th gear drops the rpms 10%.
Cost for the product is @ $500.00.
Anyone using it?
