Default Re: The official eaton supercharger thread.

There really is no boost management for a supercharger. The throttle body restricts enough air intake to allow the supercharger to spin in a vacuum at low throttle positions(same as srt6). I was planning on running a bypass valve to increase the efficiency at low engine speeds but ultimately I think that when the valve closes under acceleration it would cause a spike in the map sensor readings and maf readings that the computer would read as an error. The only additions I have on the car are the methanol injection, larger injectors, and an adjustable rising rate fuel pressure regulator which is still in the installation process. Other than that its still running the factory tune. I drove it around town under light throttle with no issues. Saturday I should be ready to test WOT and see if I get any knock and what psi I'm going to build with the setup. I moderately accellerated once to see if the Meth was injecting at the 4psi I set the switch to and got 5psi on the gauge at about quarter throttle. I connected the light on my boost gauge to the injection pump so I know when the injection is spraying. Very responsive above 2000 rpm. With the porting I did to the blower I'm thinking I may get around 8-10 psi from it. Anymore than that and I'll be looking for a larger SC pulley or possibly catastrophic failure.
