I am working on a mechanical 5.9L and was curious to what the maximum speed that engine can run at full throttle. I know some of my other 6 cylinders top out around 2700-2900 rpms. There isnt a tag on this engine to go by. Right now it tops out at 2500-2600. Just curious if that is all its supposed to do it just seems a little slow. Thanks
The govenor was disconected when we purchased it used from a dealer. It was from Loudoun County VA. It tops out at 59-61 depending on the terrain. It must be gear ratio related.
Ohhh that bus has a 6.6L. I too have a 93 from Loudon County. 6.6L is a good engine but yes these Fords are slow pokes. I think my 95 bus has a 5.18 ratio and just seems like it shoiuld do a little more than 55-57.
Doesn't the Ford 6.6 have a one piece common valve cover? My bus has six valve covers. When i started at the school in 03 they had 3 89 Ford chassis short buses that were not fit to drive though the 6.6 liters all ran great.

hmmm yes you are right about the valve cover and the air compressor is gear driven too. My bus is a 1993 from Loudon County but it has a 6.6L. Maybe they ordered some 5.9Ls later in the year. Thats interesting.....Yes our bus has a little over 230k miles and runs great. I add about 2 quarts of oil between changes and it does pretty good on fuel milage and great for cold starts in the winter.
