to all you 6.5 owners out there, is 1800rpm at 100kph ok? or should the rpm be lower or higher?

That is about what mine tonks along at (1850 ish is 100 ish but I sit a tad under) and it seems to be the sweet spot (33 inch tyres 3.9 diffs and 4L85 tranny).
When I put the 35's on it is def not as happy on the bitumen (runs a tad hotter and uses more fuel esp if the Van is attached).

But... mine is not a P400 and those Cobras' are pretty much a different critter entirely to the older 6.5's.

Peninsula Engineering in USA recently advised me the 'sweet spot was 1900rpm for best economy. This was also mentioned by the fuel injection guys in Bunbury who set the Standyne pumps up. Mine runs at 2000rpm with 3.9 gears and 32" tyres, so should be close to perfect when i upgrade to 33"

my next question is : who is competent to tune and dyno the DB2 IP in the Melbourne area?
I have "viewed" the usual youtube stuff, but I'm guessing there is more to than that eh?

Sorry Ralph mate, no idea personally :-(

Quick update on increasing oil volume to our undersized sumps IMHO and cooling folks. New bar has cleared the path for best to date radiator airflow.
Oil coolers sourced/mentioned earlier are quite the tight squeeze but doable :-) GU headlights and a near comp bar/80mm chassis shorten make it a little trickier but again still doable :-)

Nah sorry mate, just been flat out lately. The passengers side still needs the PS cooler lines relocated first which is a pain but I'll get there eventually:-)

I know, work is such an inconvenience at time! One thing for sure is you wont have oil over heating issues this weekend.
