Boost power to your P7100 pump.

These are the smallest delivery valves that we offer as an upgrade, these delivery valves flow up to 35cc’s more than the stock pump, that’s enough flow for a potential 50hp over stock.

These are the cleanest burning delivery valves we offer and are great for a daily driver or tow rig looking to minimize EGT’s.

In the P7100 pump, the delivery valves are essentially “check-valves” installed between the pump and the injector, controlling the overall amount of fuel that goes into the injector before it is sprayed into the piston bowl. Consequently, a larger delivery valve allows a longer duration of the injection event, thereby increasing potential power. There is a tradeoff, however, as a larger delivery valve increases duration it results in a longer, less efficient injection event. While the increase in flow does produce more power, it does so at the expense of heat and smoke. A smaller delivery valve paired with the same injector will have a shorter injection event, this results in a clean and concise burn, which will make less power but will ultimately drop EGT’s and be more efficient. As a final note, stock/small delivery valves become restrictions around 3000rpm where a larger delivery valve will maintain peak flow throughout the rpm range. This is a must for those seeking high-rpm power.
