Some of you may know that I am starting a project to build a high MPG car. I really wanted to start with something that got 50 MPG and improve on that but I just can't find a good/cheap car to start with so I think I am going to use one of our Miatas for the project. While surfing a Geo Metro forum I saw someone who was taking their three cylinder and turning it into a 2 cylinder. I'm wondering what the effect would be if I killed fuel/spark to two of the cylinders on a Miata while cruising around 50-55 MPH. Anyone want to venture a guess? I know my HP would probably drop by more than 50% (not a big deal to me during a high MPG test) but would the car still run or is there something that would mess up (engine imbalance?). I have read that an engine runs most efficiently when the throttle is wide open so this should help to open it up quite a bit. I have a Link ECU so I have a lot of control over the spark/fuel that I would not have on a "normal" Miata. It should be easy to kill the injectors (say cyl 1 & 4 - aren't they on the same coil?) and one of the coils with a switch. Get the car to 50 MPH, flip a switch and push further down on the accelerator to maintain the same speed (or decrease speed a bit).
I'm open to any suggestions (other than people saying it is a stupid project). I haven't spent much time thinking about this so don't tease me if I overlooked something very obvious.
