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) ![]() |

Dismissing someone as a "nay sayer" precludes the possibility that * they know something you don't*.
That said, this project is worthwhile, IMO. The object of any such undertaking should be to do everything possible to ensure that the modification survives the test period. The suggestion was made to use sound engineering principles that strengthen the existing materials. This was dismissed by at least one person that doesn't recognize sharp edges even when he blows up the pics. It's obvious that some here have little/no real world experience in actually building things for a living. A fella that has 20ish years of experience of NDT in the aircraft industry *knows something you don't*. I have been working on my own weight reduction in the same area. It is only worthwhile in the narrow area of autocross. The first section of testing is about over....is the basic precept worthwhile......It seems to be. The next section is the actual weight reduction. This would have gained about 300 times the rotating weight loss over what has been described here. That may be worth a tenth or 2. The bits needed are on the shelf.....but I'm selling the car. The next owner can deal with it. |
