Even with a .75 overdrive and 11R22.5's, that gives you 58.14 mph at 1900 rpm.

I wouldn't want to hold an 8.3 at much higher rpm than that for extended periods of time.

are the cummins a lot lower RPM than the IHC's?

I know you can run the DT's forever at 2300-2600 with no issues... most of them are redlined at 2700 RPM and make max power at 2300 RPM...

The Cummins 5.9 is more than happy to run down the road at 2800-3000 rpm.

The 8.3 is a completely different animal, however. Peak power is around 1700 rpm and redline is 2400-2500.

If its redline is 2400, then I'd have no issue giving it some throttle and getting on down the road with it.

It may very well be governed not by RPM redline, but by computer.

For reference my bus is equipped with 8.3 Cummins, 3060R transmission,
5.38 differential ratio and 12x22.5 tires. 2000 RPM equates to 65 mph and
2400 RPM gives 85 mph. The R on the transmission denotes a hydraulic
retarder for those with inquiring minds.

The bus looks like a twin to the one Aaron started with on the Brocolli Bus.
Same year same drive train but with fewer miles,

Hi, Deftone,

I would love to meet up with you! I tried to send a private message with my phone number but I'm sure I can just give it to you here. (203) 682-5061.

Thanks!
