Are you running a 3000 allison?<br />I'm assuming you have serviced the fuel and air filters lately? The HP is determiined by the injectors, fuel timing & fuel setting.<br />I'm not at all familiar with propane injection. I believe the diesel can take the extra boost but I'm wondering about all that extra heat in the combustion chamber. You may have to weigh the expense of installing this system plus setting it up against leaving it the way it is and planning to arrive later to your destinations.Anonymoushttps://www.blogger.com/profile/01517188475250181833noreply@blogger.comtag:blogger.com,1999:blog-18449820.post-63941601533662148052010-09-13T13:29:23.852-07:002010-09-13T13:29:23.852-07:00Hi John,
thanks so much for sharing your knowledg...Hi John,<br /><br />thanks so much for sharing your knowledge with us, the site is great.<br /><br />I have a 1993 Thomas Saf-t-liner with a Cat 3116. As I understand it this is the 185 horsepower engine.<br /><br />I converted this bus to an RV and we've taken a number of trips in it already. I have a number of questions I'm hoping you can help me with...<br /><br />First, the bus is governed at 2800 RPM or so and that gives it a top speed of about 60 MPH. This would be fine with me if it could maintain 60 but even the slightest grade drops the speed. I realize 185 HP is not a lot. I'm wondering if this is to be expected or if there may be a problem.<br /><br />Second, I understand this engine came in multiple horsepower ratings. What accounts for these different HP rating for the same engine, is it injector size, or more than that?<br /><br />Lastly, I'm considering adding propane injection to give me a bit of extra power for hills and such. Do you have any insight/wisdom regarding such systems?<br /><br />I'd like to thank you specifically for your note about the Thomas buses overheating on hills. I'll be adding the "pre-cooling" switch to my bus soon to solve our overheating problem.<br /><br />-BrianBunedogglehttps://www.blogger.com/profile/02735289916026662541noreply@blogger.comtag:blogger.com,1999:blog-18449820.post-75770953650214937552009-12-22T16:31:41.971-08:002009-12-22T16:31:41.971-08:00Hey Rod,

The 3116 has a history of the steel lines along the governor side of the block rubbing through and creating cavitation. If the hole is small you might not really notice a difference at first. This is where I would start. Once it dogs again check the fuel filter, if it's close to empty you obviously aren't getting the fuel you need. If you have a fuel priming pump start using that when the engine starts to die off, this will also tell you that the fuel system is lacking flow. One other tip is to put the fuel line before the secondary filter (closest to the governor) into a clean bucket of diesel and see if the engine runs better. But, I would definitely start at the steel fuel lines first......Anonymoushttps://www.blogger.com/profile/01517188475250181833noreply@blogger.comtag:blogger.com,1999:blog-18449820.post-59315689762968553572009-12-21T16:29:23.584-08:002009-12-21T16:29:23.584-08:00I am having a very simalar prob with a 960F fronte...I am having a very simalar prob with a 960F frontend loader can idle all day but when you go to use it in about 10min experencing major powerloss the power is never up to full but after 10min the loader just falls on its face any ideas?Rodhttps://www.blogger.com/profile/11879257964112215035noreply@blogger.com
