Start hanging out with people who know their stuff. Ask to come watch as they do stuff. Ask questions to learn more. Most people don't mind teaching people the correct way things work. Be cautious though, don't ask too many questions. That tends to get on peoples nerves. Just watch and learn, but if there is something that totally stumps you, then ask about it. Best way though is just hanging out with people who know their stuff. That, and read forums. Read technical forums (where no B.S. is getting slung like monkey dung), and just analyze stuff until you understand it.
For instance, if someone says "my boost was spiking to 22 lbs because I was running a .70 A/R," then take your time to decipher what that means. If you don't know what boost is, look it up. If you don't know what A/R is, then do a search for it. But attempt to learn it on your own before asking somebody. That does two things....doesn't annoy people who *do* know, and helps you learn. Because you will have to read a ton of stuff to figure that out, and in the process, you will learn even more stuff about cars. This applies to any car related technical sentence you may see.
As you learn more and more about cars, feel free to ask more and more questions. The more you know about cars, the less # of people know more than you, which in turn means less and less people will be annoyed by your questions, the higher your knowledge is.
Anyway, hope this was a decent answer to your question
