> I have not tested this since last year but several checks found mileage to
> be from 27mpg to 32 highway depending on driving conditions and the
> adjustment I made to my pressure sensor also the ignition has much to do
> with mileage when the compression is this low. But the car starts always
> on the first try and it sure beats paying 400 dollars a month on gas two
> years ago when I drove my Dodge truck with the souped up 440 engine to
> work everyday. In city driving I have not tested mpg but may do so in the
> future. My ignition consists of a Pertronix Igniter,  high current 50,000
> volt coil and Torque Master Spark plugs. A high power ignition system is
> needed when compression is intentionally made low (mine was by accident)
> because a standard ignition would not sufficiently burn fuel (hence, you
> guys that had weak spark before had crappy gas mileage and poor
> performance). A large gap on the plugs are needed as well as wire wound
> plug wires (electricity looks for the least resistance for spark, on
> carbon core wires at very high  voltages the rubber jacket close to metal
> is the path of least resistance that is why spark crossfiring happens in
> souped up systems). The gap on the plug must be the largest the system can
> handle without arcing or melting (I melted a see through coil on a Ford
> engine with a monsterous high current home made ignition system), because
> your objective is to burn as much fuel in the cylinder to extract maximum
> energy without over heating or preignition (out of control high speed
> explosions).

> I performed an awesome ignition experiments years ago . If you want to
> hear it just ask since this is a completely different subject.
