ok, so my car is only going up to about 18.xx psi now, as opposed to 19 psi, and my friend tells me its ok, its just the humidity. how much % of humidity is equal to 1 psi? for example, if the humidity is 20%, how mch lower should the boost in psi be?

 

I think it has more to do with heat. My PSI goes up and down this time of year. At night it is slightly higher than the middle of the day. It can be a 1-2PSI difference from day to night. I am no expert, but that is what I have noticed.

 

i'm no scientist, but as you may have figured out, cold air is denser than hot air. Your turbo is a condenser. so starting with hot air, you condense to so and so, with cold air you condense a lot more. And to confirm your suspicions, water (humidity) doesn't condense. I don't know the formula though. I live in south florida, and its was a frikkin jungle down here this week, and my car was a pig.

 

Don't you mean compressor and compress?
