* Year of the Mustang: Fuel systems and specifications change from year to year.
* Type of Supercharger: Different superchargers (brands, models, and even tuning) will affect fuel delivery requirements.
* Tuning: The fuel pressure is heavily influenced by the engine's tune. A stock tune will have a different pressure than an aggressively tuned setup.
* Engine modifications: Other modifications, like upgraded fuel injectors or fuel pumps, will also impact fuel pressure.
Therefore, you cannot find a single definitive answer. To find the correct fuel pressure for *your* specific supercharged Mustang GT, you need to consult:
* Your vehicle's owner's manual (if stock): This will give you the factory specifications. Keep in mind that this is likely only relevant if the car is completely stock.
* Your supercharger kit's instructions: The kit's instructions will often include recommended fuel pressure settings.
* Your tuner's specifications: If you've had your car professionally tuned, the tuner will have set the fuel pressure and should be able to tell you the value.
* A fuel pressure gauge: The most reliable method is to use a fuel pressure gauge to measure the pressure directly.
Trying to guess the fuel pressure without knowing these factors could seriously damage your engine.
