40-120

50-120

that is what i was expecting

now, i wonder what happens to output when you get case pressure to 240?

hehe


I dropped a stock injector in there to fire it up and here the rest of them. Sounds good and ran smooth.

Case pressure as follows, its 33* outside right now.
Idle is 800 rpm
High rpm is 2300
No load

No KSB:
80psi
150psi

KSB on:
150psi
200psi

I'm surprised to see that much of a difference with the KSB on and off.

So you are turning voltage on to manually activate the KSB, right? And the earlier trucks need to turn off voltage to turn the KSB on?

I wonder if the earlier trucks have that kind of a change.

Don't worry, in due time, good things should not be rushed.

Sounds like a volunteer to watch the gauge while I watch the road.

You have the gauge mounted in the engine compartment?

Where is it tapped into?

Umm, how would you read it when your driving? The gauge is mounted on top of my CB on top of the tunnel.
The injection pump. You'll see it in pictures when I take them one day.
