If so are you guys happy with it as far as the pressure changes and pressure loss!
That's why you're missing out on all the available Lotus performance - no flourine, chlorine, bromine, or radon!! rotfl
How did you get all the water vapor out. It is by far the thing that contributes to pressure differences do to temperature. I imagine if you have a very, very good dryer system in line after your air compressor your tires pressures would be practically almost as stable as nitrogen. In fact nitrogen is used for stability mostly because the equipment used to put it into the containers we get it from is equipped with very, very good dryers.
The humidity in the air pretty much condenses in the bottom of the compressor tank. The air that comes out of a compressor is relatively dry.I thought this might be pertinent to your question.
Nitrogen will expand less than air when heated and thus is better as a tire pressure regulator for tires that heat-cycle. The main reason for this is water vapor - humidity. Besides the fact that it just expand more and therefor gives a much greater spread form cool to hot, different air contains different amounts of humidity from day-to-day, morning to afternoon and so on. You are always trying to guess what the hot pressure will be when using cold pressures to set hot ones.
Um...PV=nRT for air and pure nitrogen. His tire pressures do not remain constant across the temperature range unless he is somehow able to defy the laws of physics.My buddy Jeremy fills up with nitrogen at the track and loves it because his tire pressures remain constant across the temperature range.
What he said.I tried nitrogen in my race car for a year or so, going on the theory that the tire pressures would not change as much with temperature due to the lack of water vapor.
In practice there was no difference, so I just use compressed air now. I've run the same tires long enough on the same car that I can set cold pressures and get the hots to come out within 0.5 psi.
