Displacement on Demand...make your own?

look, if you are going to dispute what i said by quoting me, dont leave out the part that makes my argument make sense.

sorry to get snappy, but it annoys me when people dont read your post then argue that what you said is wrong.

i said that the valves would close at BDC, also known as bottom dead center. this way, when the piston moves, it will only be creating compression. then on the way down, the air decompresses, and has the effect of neutralizing the compression of the other cylinders.


another "magic" gas saver that works (provided your car is carburetted) is adding a small amount of acetone to the gasoline. about .003-.002% will do just fine. search for it. its actually very interesting.

actually I didnt catch that BDC part greygoose, sorry about that!

no, its fine... ive done it myself many times.

I'm not sure... to even talk about this makes us the craziest, most bored people in the whole of automotive forums... and Jamescase 10 is the headmaster...
Oh what great leader do we speak of next? Peanut butter as an oil additive? Wood spoked wheels as a method of weight reduction? Driving only downhill to save gas?

Welp.

I have a '96 Rodeo I'm getting rid of soon. So I decided to try this. I actually tried it before I found this thread. I'm quite familiar with the mid-80's Caddy 8-6-4 and what a stupid idea it was on a carbed vehicle.

Anyway, yes, it runs rough. But once up to speed it runs well. And, after three days of running like this, I have 200 miles on half a tank. I filled the tank before I started this. I'm only donig this for a week to satisfy my own sick sense of curiosity. So I hope in the process I answer a few questions for you all as well.

As expected, a significant loss of power. I can still get up to highway speeds but it takes a bit longer. My original idea was to have a switch on a few of the cylinders and turn them off once up to speed. My problem was figuring out which ones to turn off to balance the engine. After reading all this, I've decided it will only be a week long experiment.
