Why are you so surprised, it sounds about right to me. 4.5/14 = 32% gain. 132% of 304=402. I assume that losses due to heat would be countered by an intercooler and additional tuning.

Nope, not what hes saying at all. in a normal engine, it draws fuel and air in, then compresses them, then ignites them, and forces the exhaust out. Problem is, when you compress a gas (like air) it heats up. If it gets too hot, it will ignite the fuel before you want it to. In a turbo charged engine you can't compress the air as much before this happens because you have already forced 30% to 100% more air into the cylinder, its 'pre-compressed' if you will. This whole problem gets avoided with direct injection because the fuel is added after the air is compressed. Air can't burn on its own no matter how hot you get it. It needs fuel.
