Holley/Demon Carb stumble

PRH said

I suspected there would be less pressure drop with the system pressure set lower.
So, it looks like there would be less than 1/2 a pound differential between the set pressure of 6.5psi vs the max consumption flow of about 1 gallon in 85 seconds.
That’s how I like to see it, so I’d leave it set like that.

I not too optimistic this will solve the laying over problem, but at least we have a good handle on the system capabilities, and know it’s up to the task of CF’s requirements.

Holley says 9 psi is the max that should be run. So that is what i have been running thinking it was the fastest way to keep the bowl full. Any you could never convinced me otherwise, had i not gone through all of these test.
Glad that i did these test. A Real Eye Opener. Never thought about turbulence in the fuel bowl with Higher pressure and never ever would have believed that lower pressure equals more steady flow.

We got a little frustrated with each other(because i Knew you were wrong:poke::D) but i'm glad i did the test to find the Truth...........OK ok, that you were right!:thumbsup:
