inspired by a recent threat here about lightning gears and there benefits ,i decided to give it a shoot and wire edm 1st and 2nd gear .the weight difference form stock to modified is
3rd gear .3764kg ( the lightest gear to slow down for shifting) 2nd gear was .5078kg is now .4398kg 1st gear was .6754kg is now .5468kg gears have bin cryo treated after the machining for testing the transmission will be mated to a 200hp /4 engine i let everybody know if the gears survive and if it makes a difference in shifting Attached image(s) ![]() |

Why would constantly meshed straight cut gears shift faster?? The straight cut gear teeth have nothing to do with the faster shifting. It is the lack of synchros and big locking blocks instead of dog teeth that make the shifting faster. Since this type of gear engagement is only practical for racing they also use the straight cut teeth. The straight cut teeth are noisy but there is less friction loss than with the angle cut teeth.
