Well I had a peak of 648 pre turbo and 570 post turbo and a cylinder difference of over 50 across the range.

What are your thoughts.

Keep your eyes on the road or you'll have an accident!

Could get some useful info from that but what sort of load did you have on it, if that was just cruising load then I am not surprised.

:shock:

That'd have to be 50 litres swept volume at least. That's a hell of a lot of RPM for anything bigger than that. Turbine differential temp isnt big enough for it to be working very hard either.

I call: :bs: (or you need new glasses, that's a fairly decent large truck engine if you devide those numbers by 10.)

google it. . . i did, im not posting the link.
Wow, hang on, sounds like it may have another meaning! :confused:

'Black Dogging' as I know it is when someone says "my xxxx is better than yours" and someone comes back "with my xxxx is better than yours" (Re: my dogs better because it's blacker than yours), but all in good fun.
My mate Jacket, started a good one about tyres ;)
I guess the aussie term is a 'p1$$ing contest'.

Sorry for the confusion.

Well I can imagine what I would get if I did google "black dogging" as I know what dogging is in the UK (rude stuff outside with people watching)

You win benno, all I got is a QSK78 v18 with 12 turbo's pushing 3500hp at 1900 and peak torque of 13771nm at 1500 rpm (I bent a pushrod on one doing a tune up, but don't tell anyone)
