Hey...i was lookin for some fuel injectors for my 3.8...anyone know of a decent company?....also how much horsepower can it possibly give you?

 

If you can't cram more air into the combustion chamber then you won't have any horsepower gains. So it is a complimentary upgrade with Nitrous, Super or turbo charging, Port and Polish, MINIMAL gains with a CAI and exhaust.

To correctly choose a performance fuel injector flow rate, the following variables must be known:
·Brake-specific fuel consumption (How much fuel you are using per horsepower per hour)
·Actual crankshaft horsepower
·Maximum injector duty cycle
·System fuel pressure at the fuel rail

Remember that installing larger flow injectors only has technical merit if substantial modifications have been made to the entire induction system.

Determining the right amount of injector fuel flow is only part of the injection selection process. You also have to match the injector's operating parameters to your Electronic Control Unit. Operating parameters include both the injector driver style (peak-hold or saturated-circuit) and the resistance required to pulse the injector. Failure to properly match the injectors to the ECU can result in slower delivery rate, overheating of the injector or fuel injector driver, and even engine damage! When installing performance fuel injectors with larger flow rates, it may be necessary to recalibrate the mass airflow sensor and/or reprogram the vehicle's ECU.

If you haven't done any major mods, the stock injectors will work fine, and are probably the best for the engine. Bigger injectors will not give you more power unless the engine is capable of providing enough air to use up the additional fuel. Once you change injectors you will need to retune the PCM to get the proper A/F ratio.

 

Thank you my reiderator.
