How much horsepower will I gain from upgrading the injectors?

High flow injectors, by themselves, will not increase horsepower. When the airflow capability of an engine is increased significantly, additional fuel must complement the increase in airflow in order to support more horsepower. Thus, the proportional increase of air and fuel together will increase horsepower.

I don’t need high flow injectors. Can you service my injectors?

Yes. Injectors over time will develop deposits inside the injector preventing it from functioning properly. Our service will attempt to solve all of the problems typically associated with worn injectors. This includes stopping any drips/leaks, uniform spray patterns and flow rates to within 2-3%. This is accomplished with our ultrasonic cleaning process as well as a high flow reverse flushing. O-rings, filters and pintle caps are replaced. A full, before and after, calibration report is also provided for your convenience.I don’t need high flow injectors, can you service my injectors?

What other modifications must I do to use high flow injectors?

If the injectors are significantly larger (roughly 2 or 3 times larger than the factory injector size), you will need to modify the fuel lines/rail to increase the supply of fuel to the injectors. Fuel pump upgrades must also be considered. Stand alone/fully programmable engine management systems must be used and more importantly fine tuned.

What type of fuels are your injectors suitable for?

Our injectors are suitable for gasoline as well as leaded race gas. Alcohol/methanol is extremely corrosive and should only be used for race only applications where the user can drain the alcohol/methanol and “pickle” the entire fuel system with gasoline at the end of each day.

Hydrogen, Propane and Natural Gas injectors are also available for gaseous applications.

Do I need high or low resistance injectors for my application?

Injectors are classified into two categories.
1. High impedance/resistance (saturated) 12-16 Ohms.
2. Low impedance/resistance (peak & hold) 0.5-6 Ohms.

Saturated injectors require roughly 1-1.5 amps to open the injector. Peak & hold injectors initially needs about 4-6 amps, and once open drops to roughly 2-3 amps to keep it open.

ECU design will dictate the use of one or the other. Most late model cars will use saturated injectors

Can the factory injectors be modified?

In some cases, yes. Certain applications will use an unusual type of injector where upgrades are not available. We can modify certain types of factory injectors and increase the flow rate up to 50%.

When do I need to upgrade the injectors for my car?

The factory fuel injection system operates slightly rich from the factory. Because of this, certain engine upgrades such as low restriction air intake/exhaust systems and/or slight increases in boost pressure can usually be taken care of by the factory fuel injection system.

When airflow increases are substantial and the factory injectors are unable to keep up, larger injectors and/or fuel pressure increases are required. The factory fuel injection system can usually accommodate an injector that flows about 15-20% more than stock without compromising the idle quality or the low RPM drivability. If the air flow increase/horsepower target requires an injector that exceeds a 20% increase over stock, there are several options.

1. Re-program the factory ECU specifically for the new larger sized injectors.
2. Add a piggyback fuel computer that will allow you to control the larger injectors.
3. Use a stand alone engine management system to control the larger injectors.
