So you're saying the bore of the pump is larger? I mean, for more volume, either the diameter of the pump bore changed, or the pressure increased, right?



If I got this right, to flow more fuel through a hole in an hour, either the hole has to be bigger, or more fuel has to be pushed through faster, right?

Certain pumps are more efficient at higher voltages. For instance, the walboro pump!

Okay.

In two weeks bitch, we're racing.

purple engine eater.... just shoot yourself in the face now and get the misery over with.....

What? You're a dork. the purple box works fine for what I need it to. And it was tuned by Wade Landham back in the day!

Is your pump runnning on constant voltage? or is it still wired stock?

Any management tune by a person who does not know what they are doing can break a motor. But ignorance is bliss https://www.nopistons.com/forums/pub...IR#>/boink.gif

Wired stock.. What's the difference? I assume stock is +12v (IGN). Why would I want +12V Constant? That'd kill the battery all the time.

You know that the pump doesn't run at a constant 12VDC all the time right?
