Modding Terminology?
I've been reading threads on this forum for quite a while now, and i noticed that there are constant posts regarding how to mod, best mod for the buck... and so on! Well sounds pretty good and entertaining; however why is there no sticky or thread on modding terminology? For example what exactly is a pulley, 80mm throttle body, header, xpipe, sec 1,2....... and so on, what are its functions in a car and how does hp or tq increase by changing those different kind of items. I wasn't sure if anything similar to this has ever been posted or not, but it sure would be nice to have someone explain them in more details.

I think if you use the search function here and read the threads about said products, you will learn enough to know what is what and what it will do. Many threads even have pictures. 
Good luck.

You're a noob, so we'll cut you some slack, but do mess around with the search button and Google and you'll all kinds of info.
Pulley.....This goes on the crankshaft (the lowest pulley on the front of the engine and smack dab in the middle) and is larger in size, thus spinning the supercharger faster and creating more boost for your engine. More boost means more horsepower.
Throttle body.... Just like an old fashioned carb on the older engines (kinda sorta) . It sprays gas into the engine. Someone discovered that putting a throttle body on the car that has a larger "mouth" or hole in it, allows the car to receive more air more efficiently
Headers.....Mercedes would never use these do to emissions and noise levels so they use stock exhausat manifolds which reduce performance. Headers are like opening a window in your home on a windy day. Suddenly the car can exhale much more easily and rewards you with more power. For a newer guy to modding, you may want to go with a "shorty" header. That is a header that is larger than your stockers, but basically bolt right into place of your old exhaust manifold. Larger sets of headers will require some cutting and welding of your existing exhaust system.
Least that gets you off the ground in the modding world.
You just cannot believe the difference in these cars after modding. Literally is like night and day.
I am out of time so I gotta get moving.
