AIR DENSITY GAUGE

[dusterdave173]

We used air density gauge when we tuned race car carbs--it helped us keep track of the air

I have been struggling with my 22 ARA shooting since the humidity and temp have soared--The humidity goes up to high percentage and my ammo hates it--well...I started thinking that if I had an old air density gauge I might could discover what the thresholds are for me and my weather and rig for swings or points at which I really start to see swings

Modern racers are all fuel injected or use computers for weather so I was hoping some old racer on here might have an air density gauge laying around gathering dust

Let us know how this goes for you. Could be interesting.

Question, if you do discover that air density does affect the lots you are shooting how are you going to overcome that?
I believe you shoot factory class so you can't tune the bullet exit for optimum timing with a tuner.

My thoughts are to discover the thresholds where the ammo starts to react and hurts results. From what I have seen in the last month is a good ammo at 50% humidity may shoot very poor in 90% then go right back to winning when it lowers. So hoping to get a better grasp of what / when.
The only answer I can think of being factory class is to use faster or slower speed known good lots to “correct” and get better scores on that day with that weather. I have noted thst faster ammo seems to do better in these extreme conditions of late but am not totally convinced. Just seeking to understand more about what’s happening and hopefully come to some basic idea of what works when and why.
It has been suggested different speeds affect the exit timing and thus can be used as a “tuning” aid — that sounds reasonable but all I am aiming for is to understand how to see it coming — to figure out when maybe faster or slower lots could help
ARA around here usually allows some practice time before a match giving me time to test as many lots as needed to see what works better that day.

Your cell phone has a built in measure of the actual barometric pressure (station pressure), just need an app to read it. That plus temperature and you're set.

Wouldn't an Density Altitude measurement work for you, since DA takes into account humidity?

I use and track my DA every time I'm out shooting with a Kestrel Drop D3 and it works really well.

Tune by using lot speeds for conditions of that particular day ? May work may crash and burn but these crazy summer temps and humidity have really thrown me a curve.
