I believe they are referring to the mustang version of the 5.0, which has turned out to be a c6 corvette killer lol. 360rwhp all day long, 415rwhp witha cai/tune/midpipe change...the new 5.0 is just a wickedly awesome engine. The truck version of the 5.0 seems to be missing about 40bhp, but it still skoots all things being considered.

Got it. I found the equation for the hp, torque and time equation.

I would like to hear from one of the experts here on how this engine is running so much compression on low octane fuel without detonation.

I'm not an expert but I believe it has to do with the fact that it's direct injection.

It can't detonate because there is only air in the cylinder on the compression stroke. The fuel is injected directly into the chamber right before it sparks. Works very similar to a diesel except it uses spark not compression to fire.

Manufacturers are actually working on HCCI Gas engines now that can alternate between normal direct injection spark ignition and diesel type compression ignition depending on the load on the engine and RPM range. This has huge potential for fuel savings if they can work around the inherent disadvantages in emissions and engine reliability.

So... Can I add a CAI to a 5.0L without voiding the warranty?
