Maybe i should try that before I blow another one.

The problem is we can't drill a hole that long without great expense.
The solution is heat treating. The factory TT's are not heat treated. The issue is that traditional heat treating (horizontal) will cause the the shaft to bend/warp which will cause considerable vibration at 6800 RPM. If you can hang it and heat treat it, you can impart 50% more strength to the shaft and gravity with help you to keep it straight. But it's not easy to find a place to do it.
Luckily the breaks appear to have been anomolies thus far, but eventually it will become an issue for high HP 928's. |
