How to turn up the power on a Cummins pump?
Here is a brief write up on how to turn up the power on your 1st Generation Cummins truck with a Bosch VE Injection pump. Beneath the cap is a Torx T-25 screw and a lock nut that holds it. The locknut is 13 mm and has a ‘break-away torque’ of around 100 in-lbs. Tightening this screw will increase low boost fueling.
What kind of pump do I need for a 89-93 Rams?
The ’89-93 Rams need more fuel and more boost to make good power. TST recommends a 16 cm2 turbine housings where stock is either 18 or 21 cm2, this turns boost up 5-10 psi over stock. TST boost and pyrometer gauges also work on pre’94’s.
How to tune up a ve injection pump?
Take a 13mm wrench from the bottom area you should be able to reach up and loosen the jam nut. Now the more you screw in the main fuel screw the more fuel will be delivered. This adjustment will alter idle setting so more your screw in the higher the idle will become. WARNING!
What’s the boost pressure on the 89-93 Cummins?
The factory turbocharger bolted to the ’89-’93 Cummins, the Holset H1C, was designed to see a peak boost pressure of 18 psi. After the fuel mods mentioned above have been added, the boost number can be well over 30 psi.

How is the power of a pump calculated?
Hydraulic Power. The hydraulic power which is also known as absorbed power, represents the energy imparted on the fluid being pumped to increase its velocity and pressure. The hydraulic power may be calculated using one of the formulae below, depending on the available data.
Where is the power adjustment screw on Bosch VE pump?
The Bosch VE pump can be turned up by turning the power adjustment screw clockwise about 1 to 2 turns. This power adjustment screw is located on the firewall end of the injection pump under a plastic cover that will pop off.
Where is the spring tension on a VE pump?
Once you turn up the fuel, you will likely need to adjust the idle linkage to turn idle speed down. You may also need to readjust smoke by adjusting tension on the boost diaphragm spring. Spring tension is adjusted by turning the smoke adjustment screw, which is located under a small round cover plate on the top of the injection pump.
