Ran my car 2 meetings ago 388cui Ford 80a.5 .030 nozzle’s & 58 main no high speed it went 8.24 - 823 -8.23 @161.
I decided to try a high speed for the next meeting, I had read Spuds article on putting one on and used his N/A calculator. So a got a 160psi gauge with memory from Spud, plumbed it into the top of the distribution block and put the high speed on turned around backwards. Went for the first pass to work out out the fuel pressure.
It clocked the gauge past the 160psi probably around to 180 after the pass. Wasn’t expecting that much,I was only expecting around 120 psi.
