https://superchargersonline.com/wp-content/uploads/2020/03/4809643.pdfI have a 2001 w/ built engine and Paxton. It was built using a VEC along with the traditional Paxton fuel setup (i.e., 2 external pumps and the FMU).
I'm having some drivability issues so going to re-tune without the VEC, so figured now is a good time to upgrade the fuel setup to RSI's double hanger kit. Questions:
1 - What fuel pressure do I want to set the regulator at?
2 - When I set the fuel pressure, do I want the vacuum/boost port connected to the manifold, open to atmosphere, or does not matter?
3 - Can I connect the vacuum/boost port to any connection after the throttle body, or are there specific ones I do/don't want to use?
Sorry for dumb questions, I usually only build n/a engines so learning how boosted vehicles are setup (compounded by the fuuun of figuring out what the last owner did to the car)
1 = 55-60 but depends on injectors/fuel line size/WOT, etc
2 = manifold. you need it boost referenced
3 = search on the forum. You connect tap into manifold around the MAP or use the ports by the thermostat but that depends on what you want to do.
