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) ![]() |

I thinks its very cool... no pun intended. I can't see EDM causing enough heat to re-aneal the gear teeth. EDM is done under oil/or coolant. Should only get hot right next to the cut only. My only concern would be overheating the gear oil. I think the extra holes will cause some major increases in foaming. Too much oil on gear stacks and bearings causes a lot more friction and heat.
