There must have been a printing error, because they can be chipped to 300 hp.

And regardless of the fuel input you can add propane and push a lot more power that doesnt require additional diesel fuel.

I had 11,000lbs(or so) behind mine this week.Even with 3:42s and a zillion miles,the old 6.5 amazes me.I dont tow a lot,but couldnt see how you would need much more than our trucks make stock.Granted the bobcat doesnt sit as high or as blunt as a camper ect,but really felt strong to me.My 454 1 ton couldnt hold a candle to the 6.5 loaded with same weight

Didn't mean to burst anybody's bubble or anything but I did find that article a little disturbing. I am very happy with the power my truck puts out and I do feel it will pull at least as much as a big block gasser.

my seat of the pants opionion. My 6.5 TD will pull the same and just as good as a 99 f350 7.3 joke. Was lucky enough to hook to the same trailer/ load once with the work truck and my truck. THe better part, my 6.5 started rollin away with the trailer soon as foot off brake. THe joke, you gotta give it fuel to make enough power to start movin and doesn't amke any power till the turbo spools up. Plus i like my truck alot more than any ford.

We took brothers powerstroke on a 6x6 retrieval.Ran well,18 mpg(with a utility bed,not aerodynamic) but listening to that loud motor made me like the old 6.5 even mmore,plus 3 more mpg.

So I been lookin' back over a couple old Diesel Power's and in a write up on the Stanadyne DB2 it says the pump supports motors with as high as 200 HP.

I would assume that unless the displacement of the pump is enlarged there is no way you can get more than 200 crankshaft hp from the pump since it simply can not pump enough fuel.

It has been my understanding that the only difference between a DB2 and a DB4 is that the DB4 is electronically controlled and the DB2 is mechanical.

So is there no way to get more that 200hp from our 6.5's?

Recheck your math. The article said the DB2 can support up to 50hp per cyl = 400hp. With marine injectors, intake and exhaust mods, boost increase to 15 psi., and the IP turned all the way up, you can make a reliable 300-320 hp from a DB2 without major engine or IP mods. If you want more power, the DB2 can be modified to acheive the 50hp level, but the 6.5 won't handle that hp/torque level very long without extensive ($) modifications to the motor, and you will lose low rpm drivability.

I wish you were right on that Husker. Get out those reading glasses!

Id like to throw an HX35 thats in my stash(non w/gated ) and my 4911 pump on the old 6.5 and see what really happens.Crank up the fuel rate bout a 1/2 turn with a tad adv on the timing and tune with the pyro from there.I bet you could get 275 horse w/o a cooler or meth/water.But after the rocker arm,valve spring fiasco,and then using the WRONG hole to reinstall the i/p,i swore i would never pull it apart again.The HX looks like the same pattern as our GM turbos,and the discharge even looks like its clocked right and spaced to hook it up factory looking.Next time I do a turbo on it,the inner fenders coming out

[Oldsmoke]

Is the 4911 pump an American Bosch? I'm thinking that might be what's on an old DT 466 IH I have laying around. Looks like the DB2 only a little bigger?
