Here goes...
- Air enters intake/airfilter
- travels through intake piping and through turbo
- air exits turbo and moves to the intercooler
- charge air exits intercooler and goes to the throttle body/intake manifold
- combustion occurs and exhaust gases are released by the exhaust valves
- exhaust travels through header/manifold and up pipe
- exhaust enters the turbo and spins the turbine, which turns the compressor wheel
- the exhaust gases exit the turbo or the wastegate and continue out through the exhaust

It's a good read and will get you started on understanding the basics of your car.

I was under the impression that because you had more space, because the intercooler was bigger that the turbo could produce more air than normal into the intercooler. I see now what you're saying.
Thanks Billy!
What about alcohol injection and how does that increase your boost?
I'm not doing this just wondered, I know people that have this done. (Non Subbies)
