Injector Service Process

Your fuel injectors are the best place to find new power for your motor!

Getting Your Injectors Balanced & Blueprinted

Here is what we do:

Get a base line reading on them as they came out of the engine.
Information is downloaded into a computer (flow rates are in CC per minute).
Check spray pattern and reverse flow to check for contaminants.
Strip down the injector.
As it is being ultrasonically cleaned, the injector is opened and closed at a desired pulse width with a programmable fuel management system.
Injector is checked for any remaining cleaner.
Injector is brought up to a certain temperature and checked with a strobe to see the fuel atomization.
Electrical windings in the injector are checked with an oscilloscope and an ohms test performed.
Three hydraulic tests are performed before and after cleaning.
Install new pintle caps, o-rings and in-line filters
Supplied with a Computer Analysis Sheet

Once the process is complete, the key is for all the injectors to be within 0-2% deviation of one another. They should not exceed a 4% range between one another. The process improves:

Flow which is critical under high rpm in relation to horsepower
Fuel Atomization which contributes to the torque rise in the motor

Marren Fuel Injection has found that balanced and blueprinted fuel injectors are essential to total performance and can add a significant gain in horsepower.
