Boost power to your P7100 pump.
These delivery valves are for those who want a little more power than the 055’s can produce, but with less smoke/heat
than the 7mm’s. Capable of flowing an additional 65cc’s over the stock
pump, these delivery valves have the potential to produce 100hp over stock while retaining manageable EGTs.
When it comes to the fuel side of things, there are 3 aspects of the
P-Pumped trucks that determine how much power can be produced; the
injection pump itself, the fuel injectors, and the delivery valves.
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.
