Cummins Powered Chevy

OK,
Have the oil pressure sender / gage and fuel pump hooked up. Oil pressure is identical to manual gage. 55-70 PSI

Didn't think I'd need the fuel pump, with the massive low-pressure pump on the Cummins. Wrong.
Hooked it up, and immediately a different driving truck. Smoother, quieter, and a wee bit more power. Less smoke.

Had to buy a new connecter head. I could see the wires, but the connecter got eat by the rear of the 5.9L Cummins.

Since I have hooked up the electric fuel pump to trigger off oil pressure, the cummins is tamed.
Quieter, smoother, less noise.

When I moved everthing powerplant back 2", my shifter boot was not centered over hole. Had to bend shifter neck to align shifter. Also, since I raised the cab, the tranny insulator block would not stay there. Trimmed the hole at rear to accomodate setback shifter tower. Bought a package of rubber inter-link shop floor cushion which matches my floor cover color. Put 3" of rubber sheet insulation under tranny tunnel, filled the hole, and mounted my shift boot over. It is simply amazing the reduced noise level. My XM stereo required 14 volume setting at freeway speed to hear it. Now, 6 is audible. SIX!
I can carry a conversation in the cab.
Everything works perfect. No leaks, not even a weep. Oil pressure works perfect, charges perfect....

I have to drop my exhaust from the turbo, and remove 1/4" of metal where the pipe is too close to a cab seam. Vibration on decellaration.

Have AC to charge. Bought a Dodge Cummins AC line set off eBay cheap and will replace my lines, to fit the Nippon Denso AC pump. Will notch and drill mounting holes access in right frame.

Still running 6.5 intercooler with rigged pipes. Will put AC condensor behind radiator support and put in Cummins intercooler. Christmas break project. Probably little change in performance, but cosmetic change.

Have yet to install the rear bed 2" lift, as will have to modify fiver hitch. Want to install a hidden hitch, with drop in fiver and Rhino line bed, and Rhino 50 gallon tank.

As far as front independent suspension being too weak for Cummins. Cannot tell the difference.

Still tinkering, but buggs are one by one going away, and drive-abiltiy is constantly improving.

Empty mileage is now about 19. Which with the 265/16 oversize tires is good mileage.

Like the Mastercard commercial says, I can buy bolt on power for $$$, but to hear the 12V idle ---priceless... [img]smile.gif[/img]

hey dogdiesel
is that cummins a 12 valve or a 24 valve. If it is a 24 valve and if you want more power out of it put the biggest fuel injectors you can put into it while still using the same fuel lines you will be putting out about 400HP at the rear wheels

[DogDiesel]

It is a 12V.

Power is fine. I can pull more on a trailer than I can stop. I use it to tow, therfore have no dreams of running with the Mustangs and Corvettes.

Thanks

I got to see Wayne's truck over the holidays it's a great swap he did a first class job on it.

Thanks for letting crawl all over your truck Wayne I really enjoyed looking at it.
