Jus about all finished.

So I have a freshly rebuilt 6.1 stocker from Rob. I also have a new compound setup installed for Diesel power source. I went with the ball bearing turbo and vgt option and the instructions clearly state that the turbos need a full synthetic oil. From what I know synthetic is not recommended for a proper break in on the engine. Suggestions please

12 Valve 5.9, HX35/S475 (171702) Dynomite Diesel Stage 2 Power Jet Injectors, PPump set at 480cc. 60 psi manifold pressure, NV4500. Well, this weekend I found the limit of my clutch. 5th gear, powerbraking at road speed to build boost, ran right through the clutch. Does this mean I am making more than 450 hp and 1000 ft lbs of torque?? That is what the clutch is rated for. I had thought a couple of days prior I felt it slipping in 4th at WOT. I guess that was the case....

For Rear Main Housing, and Front Gear Box (not the outer cover), is anyone using permatex or RTV, instead of the paper gaskets? I think the seal would be better and hold up longer, but also seems tricky to pull off the right way. Thoughts? Thanks, SW

I really want to stay away from a ceramic clutch. Most people are suggesting at my power level of around 600hp that a ceramic dual is what I should get. I hate a grabby clutch. Anyone run a triple organic clutch?
