Re: Boost testing on my crossover manifolds
Stock regulator is referenced to the atmosphere and not the engine or its boost. I made up an analog "computer" out of a fuel pressure regulator to add fuel pressure above some value of boost. I chose 15 psi as my starting point and above 15psi the fuel rail pressure increases a psi for each pound of boost above my chosen value of 15. Thus at 18 psi boost the rail increases 3 psi etc.to keep A/F in line with one another. Enjoy Woody
