This LS engine uses a static fuel pressure that can easily be set with a C5 Corvette regulator / filter combo. I hooked up an electric pump I had laying around for bench testing.
Redneck engineering at its finest!
Fire it up!

Before going back into the car, I needed to address the mismatch between the Porsche electronic pedal, and the one that the Chevy controller was expecting. I really tried to keep the Porsche pedal and replace the original potentiometer with the guts from the Silverado pedal, but it simply would not work. In the end, I simply replaced the entire pedal assembly with one from a Silverado. On the positive side, I positioned it just perfectly for optimal heel-toe activation.
STEP 6 - FINAL INTEGRATION
"Y0 dawg! I heard you like German Engineering, so we installed a German engineer into the trunk of your German automobile!" This is my friend and co-worker Ralf who lives in Frankfurt Germany. He had a free evening while in town so I decided to put him to use and help me test all the final wiring integration. The nicest thing about this project is that I able to reuse all of the original factory wiring for all of the engine functions. Cooling fans, fuel pump, temp gauge, tachometer and key switch all function exactly as they would in an otherwise stock vehicle.
In order to get the incredibly tight air intake elbow to fit, I did have to trim a fair amount from the engine cover hole.
Exhaust fabrication took a fair amount of time, but was pretty straight forward otherwise. I had no expectations of this ever being a quiet vehicle... I mean, come on. It's a fricking V8! The Dynomax Bullet mufflers did not disappoint.
