that's work return from the raw fuel. I was talking volumetric efficiency.
need to be more specific when you ask :)

Im not trying to argue with you Glass, but i did a quick search and found this on "how stuff works.com"
The efficiency of a gasoline-powered car is surprisingly low. All of the heat that comes out as exhaust or goes into the radiator is wasted energy. The engine also uses a lot of energy turning the various pumps, fans and generators that keep it going. So the overall efficiency of an automotive gas engine is about 20 percent. That is, only about 20 percent of the thermal-energy content of the gasoline is converted into mechanical work.

about 85% if I recall if you're talking VE on a n/a engine.
You can actually achieve over 100% VE with forced induction.

Aren't car engines like 17% efficient or some insanely low number?

I need get like 80 more hp out of my sunfire, cause it works fine with one person driving, then 2 is sucks a little more 3 it starts breathing heavy and getting chest pains and 4 it has a heart attack or figure a way for it to make more torque and hp at lower rpms lol

How do you figure?
In gear, the car sits at a lower RPM than in neutral at idle when stopped.
