Here's why:
* No Universal Setting: Fuel rail pressure is highly dependent on the specific engine modifications, fuel system components, and desired performance level. What works for one setup might be too high or too low for another.
* Safety: Incorrect fuel rail pressure can lead to engine damage.
* Tuning Required: To determine the ideal fuel rail pressure for your setup, proper tuning is essential. This typically involves a combination of:
* Measuring Fuel Pressure: Using a pressure gauge connected to the fuel rail.
* Adjusting the Regulator: The Lindsey Racing regulator likely has an adjustment screw or knob for setting pressure.
* Analyzing Fuel/Air Mixture: Using a wideband oxygen sensor or other diagnostic tools to evaluate how the engine is running.
* Making Fine Adjustments: Repeatedly adjusting the regulator and analyzing the results until the ideal pressure is found for your setup.
Recommendations:
1. Consult a Professional Tuner: The best approach is to have a qualified tuner with experience working on Porsche 944s handle the fuel rail pressure setup.
2. Refer to Lindsey Racing Documentation: If they provide any specific guidance or recommendations for their fuel regulator, refer to their documentation or website.
3. Start Conservatively: If you attempt to adjust the fuel pressure yourself, start conservatively with a slight increase above the stock setting. Monitor the engine carefully for any signs of trouble.
Remember, safety should always be your top priority when working on your car.
