Fuel pressure for supercharged Na6

[wade]

I was wondering if anyone know what I should adjust my fuel pressure to on a rising rate fuel pressure regulator for a supercharged na6 with 9psi boost ?

Is it still the normal 43psi of the injectors ?

It seems to run better with higher pressure.....

Ok so after many hours of research I pulled together this calculator to try to figure out the required pressure for my build

I have made it publicly available on Google docs and you can plug in your own settings etc into the red cells (I hopefully locked down the others)

Disclaimer : don't believe me or my maths. I have just used formula that I found scattered around the web in an attempt to try to understand how to adjust my fuel pressure reg

Nevertheless I hope this is of some assistance to member who go through a similar (painful) process

FYI I have tried to set it up to assess the feeling requirements for a na6 M45 supercharged engine with a 9psi reduction pulley. Injectors off a 99-00 mx5 which flow 265 @ 3 bar
