fuel system help for boosted L92?

[highdrum]

Guys, I am building a stroked L92(416) with ZL1 blower and heads. I will be running 9.5: with 12-14 psi boost. I plan on running 850cc injectors. I am seeking help on how to keep fuel psi stable when the engine loads up hard. PSI suggested using the signal from the factory map sensor and running it to an electric regulated fuel pump(similar to what a ZL1 uses) Can I just use and aeromotive regulator and supply vaccum to it to open up more under boost? I may have to redesign my fuel supply plans.........some help and a point in the direction would be great right now. I know carb'd engines, but am fairly new to the LS motors.

Its pretty common to add fuel under boost.

Referencing the fuel regulator to the intake manifold is the easy way the maintain fuel pressure differential across the injector. There are also fuel regulators that will raise fuel pressure at a higher than 1:1 ratio, they are called rising rate regulators. Although these are usually used to fool non-boosted systems when boost is applied. http://www.bellengineering.net/index.php?cPath=7_76

A vaporworx setup would be well suited for your setup. Call Carl and he will tell you what you need and why a pwm returnless setup is ideal. I used that setup and it worked very well on my turbo car. Check out posts 41, 66, and 228 for info.

+1 on the vaporworx setup
