pump timing

[redneck pride]

Hey yal,

was wondering if anyone ever messed with the timing on the injection pump to get more power, my buddy had his 95 2nd gen done at the cummins shop and said it was a night and day differance, thought maybe i could save some money and do it myself any help would be appriecated. Thanks

You can just loosen the bolts that hold the pump (4?) and turn it toward the head that will advance it enough or You can also jump a tooth for more extreme results.

how much would you turn it toward the head? and which way would you jump a tooth if i did that instead

1/8 inch or so.You should see a good power gain.Your boost numbers will drop slightly,and yor egt sould drop also but the hp will go up

In addition to this, you can also increase the fuel delivery rate by adjusting the fuel screw. This is another easy way to get more hp but this will increase the EGTs and possibly engine idle depending on how far you crank the screw. This is another "free" power increase possible with the VE pumps.

well got it done finally dint notice much of a differance also added a bully dog fuel pin and didnt notice much of differance either, but i have another question before i did all that she is cuttin out on top when im going into a hard pull or going up hill sounds like its starving for fuel any ideas? maybe thats why i didn't notice much hp increase?
