With the Injectormatic you can calculate the approximate injector flow rate to be used for the desired motor power. All injector flow rates are calculated at a fuel pressure of 3 Bar.

(1) Approximate engine horsepower

(2) Injector duty cycle should be 0.8 (80%) or LESS. Numbers higher than 80% are generally NOT RECOMMENDED. If maximum injector duty cycle is not known, use 0.8 as an estimate. accepts NO RESPONSIBILITY for errors made using estimated, unverified information. Always verify engine performance information on a dynamometer!



Fill in the above fields first (power, number of injectors etc).

You can search injectors using your car make and model. After setting model, the size of the O ring and length of the injector will be set automatically.

Please note that  the information is for reference.

Please pay attention  to the type of connector! You may need connector adapters or to change wire harness connectors.

If you can not find your car in the list or want to make suggestions, please let us know.
