Horsepower be in a 1993 Cummins 5.9 in a Dolphin Moho

As per the Subject. Whadayathink. I have found conflicting info on the web and in the documentation of the motorhome.

While we are at it, would it be a 4 speed or 6 speed Allison.

Any other comments on the coach drive line are welcome.

Thanks in advance.

The 5.9 in that era was sold in different ratings for different duty cycles. 100% power heavy duty applications were 160 HP and lower (some as low as 120 HP), while light duty applications like RV and pickup trucks could be rated 190 to 230 HP.

So yours could be anywhere from the highest HD rating (160) to the highest light duty rating offered (230). Cummins will know.

Well, Ill have to guess at the HP for now but I can count the gears when I drive it tomorrow. 🙂 Went through this a while back with a similar unit. 🙂

And, I know Foretravel made a U225 in 1993 with 230 HP B and 4 speed Allison.

So, there ARE a number of possibilities.

IIRC the 12V 5.9L in 1993 was 190HP w/4 speed and 230HP w/6 speed

400 lbs/foot torque?

most likely 190 HP

We had a 1992 Rockwood with a 160hp 5.9 liter Cummins. I thought the largest they offered in that block in 1992 and 1993 was 190 hp. I may be wrong though if they brought out the 230 hp engine in 1993.

Our 1996 HR is 230hp with the 6 speed.

Only way to know for sure is to call Cummins with engine serial number.

Many were 230 HP. Both 4 speed and the 6 speed were available and used in 1993. Lower end used 4 speed, higher end the 6 speed.
