How come everybody has such high numbers?



My truck at idle is at 13. 5 psi, and I'm running the AirDog.

 

[Huff N Puff]

25psi at idle rarely drops lower than 18psi at WOT

I'm running an older Preporator,supplied by an Aeromotive 500lbs per hr. pump, supplied by 5/8" plumbing all the way to the bottom of the tank. I'm on my original VP44. The truck has been at over 600hp for 3years.

The Preporator was from Charles Ekstam the Aeromotive was from a local speed shop,all the plumbing and wiring was all home built including the plumbing to the bottom of the tank.
