My M52A2 has direct drive and 2700 is 50 MPH!!! JAtonka is right, I ran my deuces at 2300 and that was 55 on the deuce (non-turbo's) and they were happy!!! I try and keep the tractor there at 2300 but dam its hard.

Ive got a M62 and I have not ran it that much on the open road. Finally going to get it registered this week. I am told that the M62 was a bit faster than the M543...............any M62 gasser owners care to chime in??

Don't the gassers rev a little higher? 2900 RPM?
