Has anyone run nitrogen in their tires on track, and if so what kind of pressure variation have you experienced hot vs cold? I’ve read a few places where people mention a 2 psi hot temp increase with nitrogen vs 8 psi with standard compressed air.
For background, I have a ‘19, non R with stock cup 2’s. I typically follow the manuals recommendation on track and start out 28 cold. I’ve then been aiming for around 36 hot on all 4 corners, or 36 front and 34 rear (instead of 38 front 36 rear per the manual.). I think I started doing this after I noticed better lap times during a session with lower pressure (which could have been a coincidence) and I’ve been using lower pressures ever sense. Does anyone have any recommendations?
It just struck me a few days ago that I have access to free bottled nitrogen and should probably be running nitrogen for track duty. I plan to deflate then inflate the tires three times with nitrogen to try and remove as much non-nitrogen as possible. Also, I’ll have a 10 gal 220psi tank I’ll take to the track with me for top ups.
Any recommendations or any tidbits of personal experience would be greatly appreciated (especially as it relates to our cars and the cups 2’s)
Thanks!
