Re: ford motorsport 42lb green top noise

Yes my Bosch injectors are very loud. It's because the TPI is bank fired and all four injectors on each bank turn on and off in unison making them seem much louder than they would be on a sequential injection system.

Re: ford motorsport 42lb green top noise

Our TPI cars are batch fire, all eight fire together.

As for the noise, make sure that the injector bodies are not in contact with the base. They need to 'float' on the o-rings.
