There will be a result from unigroup soon. RB30, -5's, 260 pon cams, crank trigger, light tickle of the head, twin 3 inch into single 4, E85. I'm sure you'll see the graph within hours of it being pulled off the rollers.
What timing! I'm actually in Melbourne right now! Thanks for the offer Dan. Flick me your number so we can organise something. That would be fantastic. I've always wanted to launch a Nur spec from 10,000 RPM
Box did have the billet centre plate in it. You'd be crazy to build one without it. In regards to the box being built right, the guy that did it is arguably the best in Sydney. Either way, need to pull it down to see what exactly failed but it looks like from what I've described to be a bent or broken tooth.
It's at 25 psi man. Hardly "screwing its brains out" and realistically I haven't run over 22 psi at all which is less than what most people run on -5's. if I turn it down I may aswell drop back a turbo size. There are associated costs with doing that too.
