Car Forum / Dodge / Dodge Trucks / August 200597 dodge diesel
I have a 97 dodge 3/4 ton HD with a 6 cylinder 5.9 liter 12 valve diesel. According to Chrysler it puts out 235 hp. I pull a 7,000lb 5th wheel with no problem. The manual says that the truck has a towing capacity of about 11,500lbs. I'm considering a larger 5th wheel but I'm concerned about the horsepower of the truck versus the weight of a larger trailer. I've talked to the local dodge dealer about how to increase the HP but they are not very forthcoming with information. Can someone give me some idea's about how to increase the trucks power. Thanks >Can someone give me some idea's about how to increase the trucks power. If you can find a Cummins mechanic that has his/her own shop, they will have the computer codes that will increase your HP..... > If you can find a Cummins mechanic that has his/her own shop, they > will have the computer codes that will increase your HP..... Nope - no computer on a '97... the engine is completely mechanical. The only things electrical are the starter, and the fuel cutoff solenoid. >Nope - no computer on a '97... the engine is completely mechanical.

Oops, sorry...didn't realize my husband's 95 didn't have a computer, I was answering based on my 2003 Ram....:) >> Can someone give me some idea's about how to increase the trucks >> power. > > If you can find a Cummins mechanic that has his/her own shop, they > will have the computer codes that will increase your HP..... The '97 isn't computer controlled. The electronic diesels weren't available in the Dodge until mid way through '98. > I have a 97 dodge 3/4 ton HD with a 6 cylinder 5.9 liter 12 valve > diesel.

Manual trans, 215 hp.  SignatureBruce Grant Westminster, Md 95 2500 Club 4x4(w/"Dynatrac" manual hubs) Cummins/Auto 265/70Rx19.5(G) HP does mean jack crap when it comes to a diesel. A 400hp semi will pull 80,000 lbs, but has 1,400 to 1,600 ft. lbs.of torque. >> I have a 97 dodge 3/4 ton HD with a 6 cylinder 5.9 liter 12 valve diesel. >> According to Chrysler it puts out 235 hp.

Horsepower is nothing more than an expression of torque diluted by RPM. I dug out my letter from Chrysler and it reads Horse power: 175 kW (235bhp)@4000 rpm Torque: 447N-m (330 lb-ft)@3000 rpm So how does that translate into 180 HP? >> Sorry, I ment to say doesn't mean jack crap. > > Horsepower is nothing more than an expression of torque diluted by RPM. > I dug out my letter from Chrysler and it reads > Horse power: 175 kW (235bhp)@4000 rpm > Torque: 447N-m (330 lb-ft)@3000 rpm > > So how does that translate into 180 HP? It doesn't. Dodge never offered a Cummins engine with the power ratings you claim. Find the CPL tag on the driver's side of the timing case on the front of the engine. It will tell you the torque and hp ratings as well as the governed rpm. Torque 330 lb-ft? Nope, that's a screw up, lowest rated Dodge Cummins I've ever seen was 400 lb.-ft. This sounds like a gas engine rating to me. >I dug out my letter from Chrysler and it reads > Horse power: 175 kW (235bhp)@4000 rpm [quoted text clipped - 5 lines] >> >> Horsepower is nothing more than an expression of torque diluted by RPM. > Horse power: 175 kW (235bhp)@4000 rpm > Torque: 447N-m (330 lb-ft)@3000 rpm These are the power specs for the 5.9L gas engine, not the 5.9L diesel. Well isn't that enough to fry your butt. This info. came right from Chrysler based on my VIN number. I'm going to ask them again. >> Horse power: 175 kW (235bhp)@4000 rpm >> Torque: 447N-m (330 lb-ft)@3000 rpm > > These are the power specs for the 5.9L gas engine, not the 5.9L diesel. > This info. came right from Chrysler based on my VIN number.

Uhhh.. you're sure you actually have a diesel under your hood, right? :) Your VIN should be: 1 or 3 - built in either US of Mexico B - Dodge 7 - Truck K - between 8 and 9 thousand lbs. GVW (yours is 8,800lbs) C or F - 2WD or 4WD 2 - 2500 3 or 6 - club cab or regular cab C - 6cyl. diesel ? - check digit, doesn't mean anything (to you, anyway) V - 97 model year G or J - Mexico or St. Louis assembly plant The last six digits are your serial number Yep, it's a diesel, assembled in Mexico. My serial number starts with VM and where you show a "C" for 6cylinder diesel, mine is a D. I'm in Canada. Maybe there's a difference for this market???? Dennis >> This info. came right from Chrysler based on my VIN number. I'm going to >> ask them again. [quoted text clipped - 16 lines] > > The last six digits are your serial number > Yep, it's a diesel, assembled in Mexico. My serial number starts with VM Okay - given that you're in Canada, the 'M' indicates the Lago Alberto assembly plant. > and where you show a "C" for 6cylinder diesel, mine is a D. Hmmm... 'D' was the engine code for the diesel in '98 and up. Maybe yours was a late-year build in '97, and they had already started using the 'D' designation. Regardless - yeah, your dealership just gave you the wrong info. Shocking, isn't it? :) Here's a link to give you all the specs. on your engine: http://www.dodgeram.org/tech/dsl/Facts/96specs.html Thanks, Tom. I'll now wait and see what Chrysler comes back with this time. But it looks like the TST is the product to use to give the truck a boost. Dennis >> Yep, it's a diesel, assembled in Mexico.

This time they have replied that my truck has 175 bhp and 230 lb-ft of torque. Based on what all you folks have said, I think they are "out to lunch" on the torque value. But, that's all folks. Thanks for all your input. > Thanks, Tom. > [quoted text clipped - 20 lines] >> >> http://www.dodgeram.org/tech/dsl/Facts/96specs.html > This time they have replied that my truck has 175 bhp and 230 lb-ft of Good grief... that's the specs. for the 6-cylinder GAS engine, the 3.9L V6. Guess they don't do much with diesels at that dealership, huh? Rest assured, if you have an auto trans, your engine came stock with 180HP and 420lb.ft. of torque Tom, I am not going to drag this out any further. You guys have been really helpful. But....this latest information didn't come from the dealer. It came from CHRYSLER CANADA as a response to another enquiry I sent them. The've got to be on something.

Believe me, it's a lot better than some of the other discussions going on here. At least this one pertains to a Dodge truck :) > came from CHRYSLER CANADA as a response to another enquiry I sent them. > The've got to be on something. Oh... ok. Corporate desk jockeys. No WONDER they're confused :) Ah well... have you decided what you're going to do to the engine? Be mindful of your transmission - it's an early RE model, which were the most susceptible to failure (primarily in the overdrive section) when turning up the power. We're heading off on a trip next week. I'm going to see how the truck pulls and then make a decision. We are definitely going to move up to a larger 5th wheel. But we will likely wait now until spring. Thanks for all your help. It's really opened my eyes. And I sure as blazes know what questions to ask next time we buy a truck. By the way, my last name is Lawrence too.

[quoted text clipped - 12 lines] >power. >Thanks Listen 235 HP is more than enough with proper gears. Your truck likely has a 3.55 axle ratio in it. Slap in a 4.10 and it will tow 12 to 14k prety good without adding any extra drive line strain from "chipping" the motor. |
