I am with you Jon go faster up hill and you will most likely be behind a truck unless you can do the speed limit of the cars and pickups !!! So why go faster unless you can do the speed limit of the cars !!! I had a Peterbilt that had 625 hp and the toque to go up any hill fast but truck speed was the issue ,from state to state not the hill , or the cars , and fuel mileage is not as good , right now with 20,000 mile blocks on same roads I get 6.9 mpg that’s good for me for the last 3 years with this coach pulling a trailer

You see, it’s a perfect world. You have what you want.
We have what we want.

Oh Peter … I’m SO envious!!!!! Is that a 379 or 389? Extended hood? CAT? With all those lights I’ll bet it shows nicely at night. I was looking for one of those as a truck conversion to 45′ motorhome, but ended up with the Liberty Prevost instead. I think we made the right choice, I know we made the right choice. But every 3×9 Pete I see still turns my head.

Alex says his ’01 Marathon with 12.7L Series 60 outputs 400 HP. I thought Prevost always spec’d 500HP. If the 400hp was from a dyno reading, perhaps some further investigation is called for. How do the injectors check out?
-
My 12.7L 1997 coach was 470 hp and my curent one is 515, but 14L
Typically converters always want a lot of HP, but Prevost offers choices.

Bryan, my 94 with probably one of the first 60 series put in a Prevost, is rated at 450@2100 rpm. As an aside, one of the semi’s I have on the farm is a 94 T600 Kenworth that also has a 12.7. It’s rated at 360/400@1850, the split rating is with the cruise on the computer selects the higher hp.

Bryan,
The 400 HP came from the DD website based on the model # 6067BK28. I did not check with them or Prevost based on the diesel or coach serial number.

“My 94 with probably one of the first 60 series put in a Prevost” is rated at 430 horse power and 1450 torque. I have read that with cruise control active it is +20 horse power, but I cannot feel it and don’t care. The datum plate on the side of the motor is the source. 12.7 liter.

Bernie, I would be interested in gaining a little more information regarding the 6 owners experience with running the Pittsburgh Power Box. As I understand it, you can choose the amount of added HP in 25HP increments, at what level do you run the Power Box? Have you experienced an increase in the cooling temps when using the Power Box? Did you have an EGT gage already or did you add one to monitor the Exhaust Gas Temperature? Did you see a significent rise in EGT. Do you find yourself having to monitor you gages more closely while using the Power Box? Did you replace your OEM turbo with a larger turbo when you installed the Power Box or are you still running the OEM turbo? Do you run the Power Box all the time or do you just use it to climb the upgrades at a higher speed? At what speed can you now climb a 6% grade using the Power Box without overheating the engine or increasing the EGT to an undesirable level?
Lastly, where did you locate the Power Box in your bus? If you installed it aft near the ECM, obviously, the remote lead would have to be lengthened. I noticed the HP level indicator lights are on the Power Box. With it installed aft, how do you monitor or know what level of HP you have chosen?
AH, one more question: Did you experience an increase or decrease in fuel mileage?

Thanks, Chuck

Bernie, Thank you so very much for taking the time to call me and answer the questions I had about the Pittsburgh Power Box. I can see some real advantages now to installing this unit on my bus.
If anyone else has questions about the Pittsburgh Power Box, call Bernie, I’m sure he wouldn’t mind sharing his experience and knowledge on the unit with you.
