6.5 gets thumbs up from Cummins

Congratulation! Better late than never! :D

I well cared for and properly maintained 6.5TD with a few mods is a beast not to be reckoned with!

FWIW last time I dynoed mine, I wasn't dead last there (2nd from last but still not last :D from "just a 6.5"), dead last was a stock 24V Cummins, and that was before going to ATT & FTB, dyno operator gave me some props saying that was best running 6.5 he had ever run on a dyno, guys at Suncoast sponsoring the event gave a hearty :thumbsup: for "little engine that can".

I towed a trailer to Iowa with disaster relief supplies last summer a buddy with similar loaded trailer/F250 stock 03 stroke could not match mine up the hills.

Edited to add March, 2005 Suncoast dyno results board

Perhaps 2nd to last, but I bet your close to the top if not top dog in price per HP.
 
Hey TD, really like those numbers out there.
I'm curious as to the newer diesels numbers. Being an 03, was that a 6.0 or a 7.3? It just seems that whenever I see the newer ones dynoed, they really seem to have high drivetrain loss with their power. Any reason for that?
Curious as to what you will be putting out with the new goodies on the rig.
 
IIRC the 03 Ford is the 6.0

Ha its them torqueshift tranny's. They do more than break :D They steal your HP too.
 
well, i know a few PS owners that consider themselves lucky because they got a factory 7.3 in their trucks. even so though, it's probably a 6.0 which should be pushing close to 325 horse at the crank. i just don't understand why they would have such high loss
 
I think it was a 7.3 in his, he is a pastor from a sister church, we headed to Iowa to assist after the floods there, we are sort of experts ourselves in that area, we were ground zero for Katrina, everybody on our team there had mucked mud, water logged furniture, soaked sheet rock, and experts in mold treatment/prevention, from our "Katrina Experience"
 
in 2003 the 7.3 was an option but the mighty 6.0 liter was also an option with higher power and fuel econmy so of course more people picked that. but everyone knows that story. as far as more driveline losses us 6.5ers have a 4 speed auto and 5 speed stick where the new diesels have 5 and 6 speed autos and all 6 speed sticks. so it takes more power to turn the bigger tranny. and im sure the bigger axles and transfer cases sop up power too
 
The 6.5 is no slouch when set up right

I have run some cummins and strokes with my 3500 Dually.

The early 7.3's are not too hard to stomp on off the line. The new stuff is right quick for sure.

Good to hear of a Dodge owner that will show a little respect though.

Have fun

Old thread....

Truck is fast enough to turn heads.....if I needed to go even faster, then I would write a cheque....simple as that...
 
I'm just happy to have mine on the road finally! It's a fer piece faster than the 91 Suburban V2500 with a gas 350, and has a ton more torque than the Corolla, but it couldn't keep up with the minivan or the Chevelle. Of course, the minivan and the Chevelle can't tow a 7000 lb trailer.

Chris has a point here. Fastest car I've been in is a 911 Turbo. The owner even let me drive it! 0-60 in 3.4 seconds! Wow. Now that's fast. Only thing faster 0-60 is a motorcycle or a drag racer / funny car.

wright a cheque ? LOL if you could simply do that then why oh why keep on driving the obsolete 6.5 ?

I drive relics, obsolete technology seem to work well for me. . . But i do like to keep at least 1 some what late model unit in stock. . .

Mike
 
tho work truck those i buy New n replace the Gassers every 150K n the diesels every 250K or sooner if they start breaking down. . .

Mike
 
My 95 k1500 6.5 was faster than my 99 burb even though S versus F...the extra hp and torque are no match for the reduced weight of the 1500. Both had 4" exhaust but 1500 had no gauges. I find myself backing off the throttle more in my burb as it approaches 1200f quite easily.

The thing is, Mikey, we fix these "obsolete 6.5's" because we can.

Parts are cheap, the mechanics and electronics aren't that complicated if you take the time to learn that they are different from other diesels (and VERY different from gassers), and the trucks themselves are cheap because too many others aren't smart enough to understand them. These trucks are very accessible for the average mechanically-inclined individual to work on, if they are willing to learn; around here are some of the best expert minds you can find on these trucks, both male and female - you just need to be open to learning from them. If you can't make your truck run reliably, it ain't the truck's fault.

We pull big loads with them because we can.

Slim, TD, Leo, Oregon, Me, and many other guys have pulled BIG weight with these trucks very reliably. They cannot do that in their stock form, and yelling at them doesn't seem to help that, but if you're willing to learn to make the logical modifications, they will pull hard, cool, and get decent mileage while doing so - but they can't pull outside their envelope, and it's the driver's responsibility to recognize what that is. If you can't make your truck pull, it ain't the truck's fault.

We race them because we can.

Lots of guys on here run their trucks on dynos, at the track (like ChrisK1500 has), and love to share their adventures and dyno/track slips. Most of us are quite proud of what our trucks will do, mostly because so many other people just aren't capable of making them do it. Your average guy looks at these trucks in stock form and doesn't think they will ever amount to much, but we look at them through the lens of possibility, and try to see just how much we can do. Changing not too many things turns these rigs into serious contenders... they aren't up to strapping on a modded-out Dmax of Cummins, but we knew that going in... and they didn't cost $50,000 to buy and modify, either. Bill Heath took a basically stock truck to over 150 mph. If your truck won't race, it ain't the truck's fault.

This site isn't about whether the trucks are as reliable, strong, or fast as a new Duramax. If that's what you're after, go buy one... most of us can afford to do that, if we want, which is what ChrisK was pointing out.

This site is about US, and how we handle our struggles with these trucks; it's a strong community of good friends that help each other out, learn from each other (both successes and failures), and share what we know. We're trying to make these old trucks better, stronger, and faster because we can.

You're welcome to be part of that community, but don't take shots at us, 'cause we don't need that, and don't down the trucks, because it ain't their fault they're not what you want them to be.
