Frequently Asked Questions

Which P7100 pump should I choose?

For stock or towing use, go with the OE-style replacement. The 12 mm Hot Street pump adds mid-range and top-end power without compromising street drivability. For dedicated performance or race use, select one of our 13–16 mm race pumps—just be sure to upgrade your fueling and air system.

Is a 12 mm pump suitable for towing?

Yes. When paired with matched injectors and a 64–66 mm turbo, the 12 mm Hot Street pump provides excellent torque, towing capability, and drivability—provided the fuel supply and tuning are adequate.

What upgrades do 13–16 mm pumps require?

They need high-flow fueling, appropriate turbo pairing (large single or compounds), head studs, upgraded valvetrain, and precise tuning. These are built for track or pull applications.

Do you test P7100 pumps before shipping?

Yes. Every P7100 pump is calibrated on a flow bench to ensure proper fueling curves and performance before it ships.

Can you help me pick components for my build?

Absolutely. Whether it's injectors, turbos, or plumbing—we can build a matched system to reach your horsepower target. Contact us for a custom recommendation.
