I'm running stock lines and regulators withe the 42 lbs injectors. On boost it runs around 65 or so psig. Last I logged duty cycle I was into the 80s, but it's been quite some time since I've done this so my memory is fuzzy right now.

I'm hoping to be able to run just to one bar with the car...maybe slightly less.

I hooked up the boost line to the pump booster last night (but a tear in my bloody rear seat side panel doing this). It pulls the voltage down to about battery voltage when in deep vacuum (20" or less)...when you go to atmospheric the voltage steps up and then further steps up into boost. It's a rather clever little box.

I'll try and get some pictures for you guys tonight or tomorrow. The box does generate some heat, but I think it will be maneagable...afterall nothing is 100% efficient...except for TURBOS
