318 MAX fuel economy builds?
Could you provide an example of doing it right, and another example of doing it wrong?
Could you explain the detriment caused by over atomizing fuel at the booster?
I'm open to learning new stuff.
I can give several examples of doing it wrong, but the best one is a Ford 460 in 1988. Last year for a carb.
I can’t remember the Holley list number any more, but Ford had so much heat moving under the carb it would coke the fuel in the manifold. The piece of **** would barely run after 20k miles.
I pulled the intake, blocked the heat crossover and it picked up 3-4 MPG when towing my race car. At one point it was down to TWO MPG. At best I got it to 10.
Straight junk. That’s what happens when you use heat and too much booster. It wastes fuel, loses power and is just garbage.
Of course, in about 10k it burned through the stainless steel block off plates and the fuel consumption went up and power went down.
I almost, ALMOST put an aftermarket manifold on it (would have been aluminum and I would have welded the cross over shut) but I hated that piece of **** so bad I traded it for a 1990 Dodge.
Thats just one example of not getting the fuel atomized and vaporized correctly.
There are certain people who believe that you MUST vaporize the fuel because of what someone wrote, and thinks it is THE factor in distribution (its not) and that you can never get the fuel too finely atomized and then vaporized too soon.
Ever wonder why most guys pick up when they switch to alcohol over gasoline? VAPORIZATION.
Its that simple. Guys run way too much engine temp on gasoline, which vaporizes the fuel too soon and kills some power. Alcohol loves engine temp. 2.5 times the fuel volume requires as much heat as you can get to vaporize the fuel or it just runs into the chamber and out the exhaust.
I tried everything from 6 or 7 different MFI nozzles to as high as 140 PSI at the nozzles and no matter what, you can’t get enough vaporization with alcohol without 180 plus degrees of coolant temp.
I‘m not certain that a water heated intake manifold wouldn’t benefit alcohol fueled engines.
