Hi, how did you manage you manage that, the drp's are supposedly the best box? It's all about how much you want to spend? I have just had mine built with a quaife, solid input shaft, 4th gear support, 02q selector forks and diesel final drives cost £2k. I hope to run 550-600, if it was more I would look to shot peening and superfinishing and cryo treatment.

 I used Gas'n'gears in wales, known as HotGolf on the gti forum, top man!

let me know how you get on

I think it's the torque that's done it. Around 725 nm it's running. Looked into gearsets which say they good for about 600 :/. Will be going for big power/torque next year aswell.I have a spare box which I'm throwing in. Then the broken one will be done up to a higher standard. I did speak to this guy. Very helpful.

Sounds like the torque bent the shaft so the 4th gear came away a bit and stripped the gear, I read somewhere that it can take 10 ton before it bends with a solid insert it will take 30!

i had a quaiffe gear set before and when I spoke to them the the gears are no stronger than standard, that was the semi cut one not the straight though. Bloody noisy as well!

good luck.
