Let me pick your brains for a moment...
I come from the 4x4 world. I've spent the last 10 years involved in all aspects of trucks, Jeeps, and SUVs and did some offroading, etc. What we learned in the 4x4 world crosses over to the car world in some ways.
For example, lowering the air pressure in your tires increases traction. But... it also creates rolling resistance on pavement. Rolling resistance robs a little engine power and drops MPGs and creates heat.
Now, what I'm wondering is this: Assuming you have a mostly stock street car with bolt on mods like I do and you go to a track to run the 1/4 mile, would it be best to air down or air up? I'm only a little over 300 HP at the crank and I'm on all-season tires so I'm not going to spin all the way down the track, you know? So I don't need to air down, right?
In theory, if you leave your air pressure high, you'll reduce rolling resistance, free up horsepower and speed, and might possibly pick up a tenth in the 1/4.
Has anybody played around with this to see? Or am I just dreaming?
