i just got myself a cummins about two weeks back. i am trying to go for some big power out of this thing but am new at diesel performance only built gas motors before this. i have already gotten the ats tranny and torque converter in it and i have ordered a new 4 inch turbo back exhaust. now i have heard turnin the fuel pin up will give it more power idk how much?? but i am going to try and do tht but what would be next?
Pyro and boost gaugs, Denny t fuel pin, turn fuel screw to just before runaway, turbo upgrade, upgrade airhorn, etc...... Just so u no u can't make BIG power with a ve. Most ever made was jus over 700hp
96 one ton dually 4x4. 3ks. #10 plate slid and ground a bit. Resurecting from the dead. little paint work. Flatbed. Chrylser certified Tech.
Piston Lift pump, 3/8" feed line, 5/16" return - minimal performance gain, but brought fuel pressure up to 15psi under boost
A1 studs with OEM gasket - I blew my head gasket the ONE time my boost spiked to 36 PSI
3600 RPM governor spring - see below
Turned full fuel screw - while I had the pump apart for the spring change I removed all the "lockouts" from the pump adjustments, turned my full fuel screw up significantly (still no indication of runaway), all I can say is WOW. I can roll from 40-90 in 4th gear and get there RIGHT NOW, temps are 1400ish and boost is 45 (waste gate blocked)
I did things in the order I did due to time and parts deals (group buys and good old fashioned negotiations)... I still have more on the "wishlist"... But now I am focusing more on getting the temps down. I want to do a cam swap, ported head, 3 piece exhaust manifold and intercooler upgrade... I also want to do a M2 pin, but Thomas is on vacation right now so it might be a couple weeks...
If I was to do it all over again I would probably do it in this order:
GAUGES - boost, pyro, fuel pressure and trans temp (for automatic)
Piston lift pump and fuel lines
governor spring, turn pin and full fuel screw
M2 fuel pin
Injectors (and likely more pump tuning)
*EDIT* After another run, the truck will hit 1600* if I run it WFO all the way to 110ish...
im in the coming stages of building my 91 for some serious pulling action, i dont have much right now but i guess ill shoot you my parts list.
i did a fresh pump rebuild this spring and put 370 marine injectors in it
boost, pyro, fuel, tranny temp gauges
piston lift pump swap
4 in tb exhaust- 6in stacks
built tranny- either build up auto thats in it or nv4500 swap
possible head swap if injector orifices are cracked
14 mm head and main studs
guerilla block girtle
p pump conversion, possible built to 8.3L specs with mack delivery valves = maddd fuell
o and finally, paint and body work lollll
Hey morinscummins....i see you have guerilla block girdle.....if ya don't mind me asking, how much for the kit? I never even heard of it before, until i seen you write about it. My block is currently cracked and i like the thought of putting this on my replacement engine! I watched the youtube video of it and thats pretty darn slick.
