Spud Miller's Cave / Re: New Pressure Gauge

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.

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.

That's what i came up with 2.9GPM, I don't have flow figures for the pump, I bought the the whole system brand new . Pump-nozzles-pills 3 way shut of valve,  the barrel valve leak set and main check valve and Idle check set for me with a 90 main pill in. Melted the plugs first time out.

The plugs look good. It crosses the line at 8000. It doesn't miss from to much fuel at the top end, just sounds lazy. I did have an 80 main in it and burnt the plugs.

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.

Yeah the smaller jet cleaned up the miss. I was looking for the easy way out, there isn't.
 The closest place to get it flowed is 4000km away. I'll bite the bullet at send the whole system away.

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?
