New Pressure Gauge

<< < (2/2)

Rat:
An new 80A-1/2 should flow 5.2, a used 4.94. With those numbers I would have started with the 90 main as shipped or gone super safe with an 80 - 85 which should have been safe. No other bypass/pressure reliefs in the system?

Bully:
No, I checked both the idle and the main, they were both around the rite way and free. It runs fine we just thought it was a little fat up top, so we put the gauge on to set up the
 HighSpeed and that's thrown us a bit.

Rat:
What brand is the barrel valve and at what point is pressure gauge plumbed in. Sounds like it is picking up a spike when you are coming off the throttle. Did your crew check it, zero it after the burnout.

Bully:
I bit the bullet and got the system flowed. Found a few problems with it, the only thing left the same is the Nozzels.
Got a new pump, the high speed is set up properly now. I’m just waiting for our track to open (corona virus) hopefully it’s  this year.
