Hi All,  grin

Wanted to post some pics of some stuff that is very handy and yet easy to build so you will have more power in your tool boxes. shocked

This first one is a pretty good 0-100psi (+/- 1/4%) pressure gage and a regulator setup on a manifold that is tapped for #6 AN on one end and #8 AN on the other.  cheesy The setup can be used to check (with compressed air) the opening point of check valves or such things and is very handy to use around mechanical injection but there are many uses for it. huh

Also shown is an adapter that is tapped for #6 AN to check for leakage of one-way check valves, etc. rolleyes

Howdy All, grin

Another easy tool to make that is very handy for measuring low pressures around racecars is the following.

The piece is a Magnehelic gage that can measure low and high pressures both positive and negative from 0 to 2" of H2O. cool

The gage is normally on zero when standing up and I laid it on its back to take the pic. The case is a chepo plastic box from Radio Shack and after cutting the hole for the gage and installing same, the hose connections were added. rolleyes

You can use this sensitive gage to check out places where small pressure differentials exist such as in the air scoop or underhood pressures.  huh Of course at speed you would want to be getting the indication on a video or digital pic so that you can drive.  tongue

It sure takes the guesswork out of small pressure measurements without spending big bucks! evil

Harold,

Where do you get the gauge itself?

Been working on a new air intake system and it would be nice to get some baseline measurements.

Well, it used to be Los Angeles . . . 50 miles north of Fresno now.

Dean and All, grin

Thanks for supplying the information on where to get the gages. I think I bought the pressure gage from Graingers new, but I bought the Magnehelic gage at a place called OEM here in Colorado that deals in surplus equipment. I don't remember what I paid for it but it was cheap. cheesy

I have even used the Magnahelic gage for setting up a Rochester fuel injection for rich and lean stops and by making a small adapter to go in the fuel injection port nozzle line referenced to another pressure gage that I also got from Graingers (about $40 as I recall). cool
