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.
