I'm an idiot though. Idiots write like this apparently.
They do when they insist on being right about something they don't know anything about!
So I will keep it simple for ya.
The added power comes from the bigger BOOM in the combustion chamber due to the combination of the added “air” produced by the “boost” of pressure induced by the Supercharger (yes in the chamber that was previously occupied by the intake manifold) and the appropriate fuel. More air and fuel, bigger boom. Need more explanation I could get technical, but I’m afraid you might not understand.
IF the O2 sensor can tell the ECU to get the air/fuel ratio to a stoichiometric point and IF the fuel injectors are of sufficient capacity to deliver the right amount of fuel.
The jibber jabber of the 02’s and the injectors have nothing to do with the power produced by the addition of the supercharger just the capability to produce more power. Everything has to be calibrated correctly to work properly. (you are trying to maintain the proper air/fuel mixture at all times which is around 14.7:1 for our engines or 12.0:1 at WOT)
If you are trying to understand why TRD has various generations of SC’s is a totally different animal. The 2nd 3rd and 4th gen SC still don’t have fuel upgrades so they are still ¾ a supercharger. They have an added injector you can purchase as an add on to the SC, but still not a kit and still not a good design. Wait are you questioning the engineers on their design of the supercharger,… oh no not you! Why it would be stupid to do that just like adding the smaller pulley.
Oh and to clear things up,… PRESSURE is all that it is about,… yes relative, but still the concept of the supercharger. If you understand the concept you would understand that the pressure is built up with the power used up by the engine and thus negating your statement of “extra power come from the fact that when the intake valves open air rushes in under its own power” The added power by the combustion chamber has to be greater than the power loss by creating that boost of pressure to come out on top. None the less the power is still created by the combustion in the combustion chamber due to the added air/fuel mixture(BIGGER BOOM!).
I am just having fun now,...
please tell me the error of my ways oh mighty one!
