Spud Miller's Cave / New Pressure Gauge

« on: October 06, 2019, 02:05:13 AM »

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.

Spud Miller's Cave / Changing fuel pump.

Hi,I’m new here and I’m after some advice.
I run a 388cu sbf 3v heads, Pro Mag 12. The fuel system is a Bug, Enderle square barrel valve 80a.5, 30 nozzles and 56 main pill no high speed.Runs consistent 8.20’s, at the start of last season we could run a 60 main but as we got into the season it started to get a high speed miss so we fattened it up with the 56.
So here’s the question, a mate will sponsor me a Waterman 500 sprint pump which he has just had flowed for his 410 sprint car it has 6.4%loss, that’s what’s on the tag. Where should I start with the main and could I put a high speed on it?
