I can now get 4psi sitting in the driveway. Waiting on a driveshaft to be able to take it out. Should be pretty fast now. I had a huge [1"dia] hole in one of my aluminum intake pipes. I was still making 16psi with it.

 

Wow.

How much fuel are you pushing through your 4bt?

 

I dunno I have the pump cranked up a bit to where it idles with the idle screw backed out all the way. I have no real reference point for adjustments.
