I had an oportunity to drive a PT40 this weekend and was suprised at how gengerly (slowly) it moved off the line. Certainly, I could not "feal" any torque. Is this typical?
It seemed to pick-up spead at a steady pass, and hold it quite well. An observer would likely think that the driver was being partularly carefel with speed.
I understand that this rig is much more substantial than my 1980FC31. But I expected a bit more apparent tourque. It was very quiet, unlike my front control, so perhaps the real difference was the no noise.
How long in minutes should a 6v92 white smoke after start up before air is purged; and trouble is expected? Also, the engine hours were over 7100, any thoughts about that...?

Follow up to my own questions...
My 1980 FC31 is much faster off the line than that 6V92 I drove. My guess is that it did have some low power issue. Though I now understand that some (or all?) 6V92's do have emmissions controls that do limit of the line performance.
I just purchased an 8V92 coach and its' performance totally eclipses the above mentioned coaches.
