I suppose they are right if not driven correctly, but if you are rolling into it rather than jumping on it, I can't see it damaging the crank, but I am no mechanic. What are your thoughts on this.

The C 15 refered to in the other post is in the 05 Pete 379 I have, the 900L has the 06E in it.

Sounds like a nice truck Gord.
Have you heard of Tony Welch/Welch Performance Diesel. In IA I believe and runs a Dmax in the pulls? He's built a few hundred performance class 8 truck motors and is real knowledgeable on the late Cat motors. I know he's ran over a 1000 HP on a 3406 with no problems using the OR6051 Cat turbo. IMO, don't think the crank would be a problem at all with higher than 550 rating.
I drive my truck or my son drives it when he's around. He's got a new 07 Legacy with a 475 in it set up for heavy haul and runs 9 axle out of Vegas in 4 or 5 western states. Not too happy with the Acert motor tho. I think an ISX 600 would have been a better choice now.
Anyway in the 98 379, with the Pitts box set on only 5 I broke the factory 2050 fp clutch loose. I've got a 2250 fp clutch in now and it seems to hold it on 5. But that's only for less than 10 seconds with that much fuel.. The box will default back to stock at 1099 egt post turbo so it's fairly safe. I need to send the box back to reset that for a good dyno run tho..
