What is the significance of your PSI? I know, newb question, laugh all you want but I'm just curious lol.

 

psi = pressure per sq. inch. when you hear auto guys taking about psi, they are most likely talking about boost pressure (how much psi their f/i is putting out), or their tire pressure, which will affect your launch and handling charactieristics. hope that helps.

 

can also relate to your fuel pressure...or really any kind of pressure.

 

PSI: normally talking about a form of forced induction in the automotive world. (PSI generally stands for pounds per square inch)

 

Or he could be talking about his tire pressure. That sounds more like a noob question, according to him.
