I've noticed many, many times that when a mod is proposed that someone...with out fail....will introduce the FEAR FACTOR or the RIDICULE FACTOR.
Not saying that taking care and so forth are not a good thing...just making an observation.....
Ridicule and fear are NOT scientific testing methods.
They are emotional games?

Plugging or disonecting someway the power valve circuit in a carby will result in a stammer (which if serious enough could stall out the engine) when flooring it from idle.
Not the best thing at the lights or across a busy intersection when you need immediate zip.
Other effects can be burnt head valves from lean out conditions or increased seat wear.
Also the engine will be noticeably weak in acceleration when going say from a 3/4 to full throttle condition in any gear.
Bottom line , BAD ADVICE !
In fact ,..that whole article was a complete joke.

Here's one for ya. I bought a 650 demon carb for 351c. The guy said it had a good base jet setting. I ran full throtle with water injection on. Engine ran very well. I turned water off. It was crackleing out the exhuast. I did research on the carb. It was 15.5 AFR out of the box. But why water dosn't burn?

Emotional games: "The government and every business in the world is in a conspiracy to rule your life so you can pay 500 extra dollars a year for gas. No one is honest except for me. Everyone wants to poison your gas tank. Now, listen to me solve the problem."
Logic: If acetone improves vaporization of fuel, and fuel is almost already completed vaporated by a stock injector, then where's the gain going to come from? Mehbe I'm just scared, but I tried it on two seperate occasions with two different fuel injection systems on my car; you can guess what happened.

As far as his political views...my guess is that if the acetone was added to fuel in bulk...there MIGHT be around a 10% avg gain in fuel economy...cleaner air. But no war profits though.

Ten percent gain? That's a lot! A whole lot!

No, water doesn't burn.... It reacts, chemically! This feature of water makes it unique;ie, rusting (iron oxide) forms when water...in any form / amount ...combines chemically with iron-based metals. Want a faster rusting? Heat the iron! Weld beads rust very fast...from the moisture in the air. Liquid water is as different from water vapor(a gas) as liquid is different from ice! It's all water...just the states are different!

Ahem! Take the driver's foot out of the equation? My foot (on the accelerator) can beat your blind, brainless cruise control any day, any time, under any conditions! I promise you! Cruise control has no eyes, judgement, or sense of smoothness (it's "on", "off", "on", "off" ... just what you don't want! No modulation...no gradients!
The closest thing we can get to a (chassis) dyno? I'm afraid not!

Ted, you missed my main point:

I'm not arguing that cruise is most efficient. I'm saying that it's most consistent, and it also removes operator bias from testing.
Like you, I can also beat my cruise control hands down at FE. But I can't be as consistent as it is for testing purposes, and I doubt you could either.

Not to be a jerk, but I disagree a bit w/ onegammeyleg. I have done alot of carb tuning on my '68 Charger. My Charger has a high lift, long duration camshaft (.509 lift on intake and exhaust w/ 292 duration) which causes a low intake manifold vaccum manifold condition. I was having problems with the 383 stalling a bit at takeoff due to too much fuel. Demon (similar to Holley) recommended a plug for the power valve because of my low vacuum (4 in of Hg). It worked for me b/c of my engine combo. I also assume that a plug wouldn't hurt or help a factory motor if the person was driving with FE in mind.
I agree the article is completely wack 'n all, but lets not jump to extremes concerning carb tuning techniques. There's alot to it.
By the way, the Charger is a rarely driven toy...the Civic gets the daily driving and the FE.

Plugging the power valve(s) in my 780 Holley really improves the performance! I do NOT know where you are coming from! Do you? Power valves are for economy...taking the "load" from the main jets at cruise... especially if the jets are "sized" (leaned) for this compromise! Proper A/F ratio with power valves is impossible! "Burned valves"? On what planet?
