i read on one site that you could hook up a smog pump as a super charger. i know that they have decent psi and cfm but the site said that you would need 4-6 of them for decent performance from a V8. i thought of using 2. i have the 4.3 CPI. would this work? i would put more on but space is very limited to this motor. would this work or what other things might i be able to pick up at a junk yard cheap that will work?

Sounds like a good idea, except for the part about 4-6 of them??? Where are you gonna' put 4-6 smog pumps?
Did the site mean 4-6 lbs of boost?
Even 2 smog pumps is gonna take a little hocus-pocus. Now if you could put a bigger pulley on the pump itself, and then split the airflow, with some air going to the intake, then you might be onto somethin'...

smog pumps put out air flow, with little pressure.

True, LT, but how 'little'?

So with a LARGER pulley, as opposed to undersized pulleys which supposedly give more HP, how much more CFM's would a bigger wheel give. I think there's something there...

CFM is airflow, PSI is air pressure.

This pump is not made for high pressure or high flow.

Just drop it, it will not work.

i think he does have a good point. if i were to run 2 of them and run them faster with a smaller pulley then i should be able to get at least 3 PSI from it. even that small amout is better then nothing at all and it will give you some boost in power with out over doing it or shortning the life of the motor. the guy also clamed that for a very short period of time he could get 60 psi out of it. he also clamed that with a 5 hp electric motor hooked up that if you put a cap ont the exhaust side of the pump that it would stop the motor. i don't know about stoping it but it would have slowed it down. heres the web site.

Why on Gods Green Earth would you want to do some thing like that. First the amount of horsepower needed to run 2 or more pumps would wipe out any boost. 2nd with GM known for crap gaskets why would you want to add any boost to a engine that is NOT set up for it.

You can't say it won't work unless you've tried.

The only part that seems hard to figure is the part about 2 pumps. Seems to me there's no room for extra components, but with an oversize pulley, you're gonna get more air flow from the pump.

Can't blame you for wanting to try it. But I agree with the guys . It does not have the volume . You would have better luck adding a leafblower to it with a power inverter. I did a water injection on a FI engine 20 years ago that gave it more power than the smog pump could . Rob

metallica21156
05-26-2005, 07:44 AM
now how is water injection going to give you more power? i thought water killed the motor. i don't know to much about so fill me in. to measure boost any boost on the motor you would just pull the tube from the back of the intake and put a T on it to split it to the gauge.it has a vacume on it or boost. its part of the intake. or if you really want you can pull the intake and drill in a new plug.

There you go - now that's thinking. Poor mans nitrous.

I think water injection allows you to run the timing more advanced, and the water cools the cylinders to prevent detonation.

Either way, I'd never try either of those things on my daily driver vehicle. I'll stick with 10 less horsepower and have the engine last 5 more years.

I was just joking, that's why I used the sarcastic eyes. If you tried that the PCM would lean it out when it saw the exhaust was rich. Also the racing fuel would just wash carbon out of the intake down into the cylinder and foul the plugs.

Water injection was used in WW2 on most Fighter Aircraft . I was called WEP Wartime Emergence power. It was used for short peroid of time.
Water injection systems are predominantly useful in forced induction (turbocharged or supercharged), internal combustion engines. Only in extreme cases such as very high compression ratios, very low octane fuel or too much ignition advance can it benefit a normally aspirated engine. The system has been around for a long time since it was already used in some World War II aircraft engines.

A water injection system works similarly to a fuel injection system only it injects water instead of fuel. Water injection is not to be confused with water spraying on the intercooler's surface, water spraying is much less efficient and far less sophisticated.
A turbocharger essentially compresses the air going into the engine in order to force more air than it would be possible using the atmospheric pressure. More air into the engine means automatically that more fuel has to be injected in order to maintain the appropriate stoechiometric value of the air/fuel ratio (around 14:1). More air and fuel into the engine leads to more power. However by compressing the inlet air the turbocharger also heats it. Higher air temperatures lead to thinner air and therefore an altered stoechiometric ratio which results to richer mixtures. Over-heated air intake temperatures can cause detonation.
Detonation, an effect also known as engine knock or pinging, occurs when the air/fuel mixture ignites prematurely or burns incorrectly. In normal engine operation the flame front travels from the spark plug across the cylinder in a predefined pattern. Peak chamber pressure occurs at around 12 degrees after TDC and the piston is pushed down the bore.

In some cases and for reasons such as a poor mixture, too high engine or inlet temperatures, too low octane fuels, too much ignition advance, too much turbo boost, etc. the primary flame front initiated by the spark plug may be followed by a second flame front. The chamber pressure then rises too rapidly for piston movement to relieve it. The pressure and temperature become so great that all the mixture in the chamber explodes in an uncontrolled manner. If the force of that explosion is severe some of the engine's moving parts (pistons, rods, valves, crank) will be destroyed.
Detonation, in any engine, should always be avoided by either lowering inlet temperatures, using higher octane fuel, retarding ignition (hence lowering engine output), lowering engine blow-by (a situation in which high crankcase pressure sends oil fumes back inside the combustion chamber), running the engine a little richer than at the stoechiometric ratio, lowering the compression ratio and/or boost pressure, ... .
Water injection is used to lower in-cylinder temperatures and burn the air/fuel mixture more efficiently thus helping avoid detonation.

In high pressure turbocharged engines the air/fuel mixture that enters the cylinders can, in some cases, explode prematurely (before the spark plug ignites) due to the extreme engine environment conditions. This situation is extremely destructive and results in severe engine damage (piston piercing). To avoid damaging the engine by detonation or pre-ignition phenomena, water is injected, along with fuel, in the combustion chambers in order to provide a water/air/fuel mixture which not only burns more efficiently and avoids detonation or pre-ignition but also provides additional inlet air cooling and, hence, denser air. The sole function of water injection is avoiding detonation.

There are mainly three variations of water injection systems. They are dependent of the location of the water injectors. The first technique consists of injecting water at the entrance of the intake manifold. The second injects water at the exit pipe of the intercooler. The third technique injects water at the entry of the intercooler and is only used in competition vehicles. In this latter variation most of the in-cylinder detonation prevention is done by injecting additional fuel which is then used as coolant (i.e. is not burned) and runs the engine above the stoechiometric ratio (i.e. rich).

How water injection works

The system is, usually, made up of 3 elements:

A water injector (similar to a fuel injector)

A high pressure pump (capable of attaining at least 3 to 4 bar pressure and sometimes even more)

A pressure sensor connected to the inlet manifold

An inlet air temperature sensor

Usually a water injection system is engaged when the inlet air temperature is exceeding a certain value, typically 40 degrees Celsius, and the engine is on boost. The most advanced systems add to the above electronic circuitry that provides 3D cartography similar to what is used in fuel injection systems. Cartography based devices take into account many more parameters such air/fuel ratio, throttle position and so on.

When I was in high school , I worked in a garage with an old air force mechanic . We used a fuel injector and pump to spray a high pressure MIST into the plenum before the MAS . The moisture would cool the air going in , thus making it denser. More air going into the cylinder. Higher compression (by a small amount) . Have ever noticed that your engine feels stronger when driving in the rain ? Its not just that the wet pavement is slicker , but the wet/cool air is denser too. Thats one reason why cars with turbos now have intercoolers too. At that age I was sckeptical too , But I had a trigger switch mounted to the gear shifter (like a nitrous button) on a fourbanger and I could tell a difference while accellerating and pushing it. The only problem was that the fuel pump I used rusted up on the inside and quit working. Rob

Antifreeze = ethylene glycol!
No.... antifreeze = Ethylene Glycol, Methanol, Ethanol, Isopropyl Alcohol, or Propylene Glycol

Antifreeze-
substance added to a solvent to lower its freezing point. The solution formed is called an antifreeze mixture. Antifreeze is typically added to water in the cooling system of an internal-combustion engine so that it may be cooled below the freezing point of pure water (32°F or 0°C) without freezing. Any substance that dissolves will cause freezing-point depression; a desirable antifreeze also should not corrode metal parts, attack rubber, become viscous at low temperatures, or evaporate readily at the ordinary engine operating temperature. It should be chemically stable, a good conductor of heat, and a poor conductor of electricity. Ethylene Glycol is the most widely used automotive cooling-system antifreeze, although methanol, ethanol, isopropyl alcohol, and propylene glycol are also used. Substances that inhibit corrosion are usually added; antifoaming agents are sometimes added as well. In automotive windshield-washer fluids, an alcohol (e.g., methanol) is usually added to keep the mixture from freezing; it also acts as a solvent to help clean the glass. The brine used in some commercial refrigeration systems is an antifreeze mixture; it is typically a water solution of calcium chloride or propylene glycol.


Ethylene = ethane with carbon/carbon double bond, hence suffix '-ene' ethylene, methylene, propylene, etc., etc.
Ethylene and ethene are the same thing, they both have the double bond.

Ethylene-
or ethene , H 2 C=CH 2 , a gaseous unsaturated hydrocarbon. It is the simplest alkene . Ethylene is colorless, has a faint odor, and has a slightly sweet taste; it melts at -169.4°C and boils at -103.8°C. Because of the presence of the double bond in its molecule, ethylene is very reactive. It burns in air with a luminous flame and forms explosive mixtures with pure oxygen. It combines directly with the halogens, e.g., with chlorine to form 1,2-dichloroethane. With hydrogen it forms ethane. Ethylene may be prepared by the dehydration of ethanol with sulfuric acid at about 180°C. It is prepared commercially from natural gas and petroleum, e.g., by cracking and fractional distillation. Ethylene has many uses. It is important in the synthesis of many chemicals. It is used in making polyethylene and saran, in the manufacture of ethanol and ethylene oxide, and as an anesthetic. Ethylene was called olefiant gas by early chemists.




Glycol = Glycogen (glucose, as in sugar), derivative, with a hydroxide ion, making an alcoh-ol/sugar - 'glyc - ol'.
Nope. Glycerol is derived from Glycogen, not Glycol.

Glycol-
(glī´kōl) , dihydric alcohol in which the two hydroxyl groups are bonded to different carbon atoms; the general formula for a glycol is (CH 2 ) n (OH) 2 . The most important glycol is the simplest, ethylene glycol, or 1,2-ethanediol, CH 2 OHCH 2 OH, a slightly sweet-tasting, somewhat viscous liquid that is miscible with water. Because of its low volatility (b.p. 197°C) and low corrosive activity, it is widely used in mixtures of automobile antifreeze . Ethylene glycol can be esterified to form polyesters, e.g., Dacron , and can be nitrated to form an explosive used in mining. It is prepared commercially by oxidation of ethylene at high temperature over a silver oxide catalyst, followed by acid-catalyzed hydrolysis of the ethylene oxide that is formed. Cellosolves (e.g., methyl cellosolve, CH 3 OCH 2 CH 2 OH) are monoether derivatives of ethylene glycol. They are excellent solvents, having solvent properties of both ethers and alcohols; they have other uses as well. Polyethylene glycol (PEG) is used to thicken shampoo and cosmetics. It can also be attached to other molecules via a process called pegylation. When pegylated to medicinal drugs, it can alter their distribution in the body, metabolism, and excretion. Such alteration can lead to improved dosing intervals and may also have beneficial effects on safety and efficacy. Pegylation can also mask certain drugs, such as interferon, from the immune system, preventing their rejection.

Glycogen-
(glī´kejen) , starchlike polysaccharide that is found in the liver and muscles of humans and the higher animals and in the cells of the lower animals. Chemically it is a highly branched condensation polymer of glucose ; it is readily hydrolyzed to glucose. Glycogen is formed by the liver from glucose in the bloodstream and is stored in the liver; conversion of glucose to glycogen (glycogenesis) and hydrolysis of glycogen to glucose (glycogenolysis) together are the usual mechanism for maintenance of normal levels of blood sugar. Glycogen is also produced by and stored in muscle cells; during short periods of strenuous activity, energy is released in the muscles by direct conversion of glycogen to lactic acid. During normal activity, energy is released by metabolic oxidation of glucose to lactic acid.

Glycerol-
glycerin, glycerine, or 1,2,3-propanetriol , CH 2 OHCHOHCH 2 OH, colorless, odorless, sweet-tasting, syrupy liquid. Glycerol is a trihydric alcohol . It melts at 17.8°C, boils with decomposition at 290°C, and is miscible with water and ethanol. It is hygroscopic; i.e., it absorbs water from the air; this property makes it valuable as a moistener in cosmetics. Glycerol is present in the form of its esters (glycerides) in all animal and vegetable fats and oils. It is obtained commercially as a byproduct when fats and oils are hydrolyzed to yield fatty acids or their metal salts (soaps). Glycerol is also synthesized on a commercial scale from propylene (obtained by cracking petroleum), since supplies of natural glycerol are inadequate. Glycerol can also be obtained during the fermentation of sugars if sodium bisulfite is added with the yeast. Glycerol is widely used as a solvent; as a sweetener; in the manufacture of dynamite, cosmetics, liquid soaps, candy, liqueurs, inks, and lubricants;to keep fabrics pliable; as a component of antifreeze mixtures; as a source of nutrients for fermentation cultures in the production of antibiotics ; and in medicine. It has many other uses as well.

I'm takin' for granted you know how to read, and if you've noticed, they both say don't allow antifreeze to puddle where dogs and cats can be drawn to the sweet smell. I can see you don't know organic chemistry either. People don't have to read a book to know that ethylene glycol is hazardous. I have used it for years to help control stray animals. Although similar, the sweet smell and taste of ethylene glycol doesn't come from sugar.

Propylene glycol is not hazardous. It is made from glycerol, though. It isn't made from glycerol derived from Glycogen, though. Propylene Glycol is a glycol made from synthetic glycerol created from Propylene. I guess you could consider this to be made for sugar even though it is an alcohol derived from an artificial glucose type of sugar. BUT your original post implied antifreeze to be made from normal sugar such as sucrose which is a combination of glucose and fructose. If we are just using glucose as being considered "made from sugar", then we can say that basically everything is "made of sugar"...everything that is or once was living. Anything with living cells contains glucose because it is how cells get the energy for cellular respriation. We know that this isn't what you meant though, because you are organic chemistry expert not a biologist.

And as far as the kidney stones from inhalin' antifreeze? Tell some soldiers who've driven hummers with leakin' coolant that you don't get kidney stones from it.

From http://www.atsdr.cdc.gov/tfacts96.html (http://www.atsdr.cdc.gov/tfacts96.html)

"Exposure to large amounts of ethylene glycol can damage the kidneys, heart, and nervous system. Propylene glycol is generally regarded as safe for use in food.......
........What happens to ethylene glycol and propylene glycol when they enter the environment? Neither compound is likely to exist in large amounts in air. About half of the compounds that enter the air will break down in 24-50 hours. Both compounds break down within several days to a week in water and soil. "I would agree that sitting in the vapors for a long time could damage the kidneys, it won't cause kidney stones. Kidney stones are caused by substances in piss sticking together. Any of the silicates small enough to become airborn would be deposited in the lungs, not your piss. The soldiers' kidney stones are more than likely caused from dehydration and minerals in the drinking water.

can anybody tell me how to get the mixture right?
Sorry about all the derails. Let's see if we can get this thread back on track. You're talking about the water mix...right? I got this info from: http://www.rbracing-rsr.com/waterinjection.html

1. Maximum Torque occurs at a 13.2:1 Air Fuel Ratio.
2. Transitional Fueling and Maximum Boost Air Fuel Ratios are about 12.5:1.
3. Water Injection is most efficient with a 50/50 water alcohol mixture.
4. Methanol, as an additive, is not a practical choice as it is prone to pre-ignition, is not safe to handle and is not readily available.
5. Denatured (ethanol) alcohol, typically 95%, is cheap and is available in paint, hardware, and Home Depot type stores in gallon containers for about $10.00. Isopropyl alcohol can be used but it is often 30% or more water by content.
6. Water Injection allows ignition timing to be more aggressive or closer to stock. In other words boost does not automatically mean retard your timing.
7. Excessive amounts of ignition retard will cause a loss of power and overheating.
8. Water to Fuel ratios should be based on weight and not volume.
9 . Water weighs 8.33 lb per gallon.
10. Alcohol weighs 6.63 lb per gallon.
11. Air weighs .080645 lb per cubic foot. It takes about 150 cubic feet of air per 100 horsepower. It takes about 12 lb of air per 100 horsepower.
12. Water or Water / Alcohol to Fuel Ratios are between 12.5% to 25%. This means Air to Fluid Ratios are between 11.1:1 and 10.0:1 with water injection.
13. Maximum water delivery should be in higher load low to mid rpm ranges tapering somewhat at peak rpms where load is less.
14. Atomization of the water mixture is directly related to it effectiveness. Finer droplets cool the inlet charge better and with less mass they navigate the inlet plenum easier for more equal water distribution.
15. Don’t flow water through an intercooler.
16. Atomized water, just like fuel , does not like to make turns thus making accurate distribution something to think about. This is why port fuel injection is the norm. Water is a fluid just like your fuel. Multiple nozzes, equally spaced in the plenum, although it complicates things, is a superior design.
17. The introduction of water will allow higher boost pressures to be run without detonation. Higher pressures will increase torque. It’s always about torque.
18. Racing high octane gasoline should be used for all forms of competition and for higher than normal boost levels. Water injection as well as charge cooling should be used with racing gas. 91/92 Octane pump gas simply will not cut it.
19. Fuel Injectors operate in the 1 Millisecond range and are not capable of long term usage for H20 as they will corrode or rust shut in a very short period of time. Unless a solenoid can open as fast as a fuel injector it should not be used to "pulse" water injection events.
20. Varying voltage to water injection pumps or using similar schemes is a recipe for disaster. You have to eliminate the variables, not increase them.
21. Fuel Injection pumps cannot be used for water injection. Water is conductive. Gasoline is not. Water will corrode an efi pump shut in a very short period of time.
22. Water injection has a cooling effect on the engine head, valves, and cylinder. Exhaust temperatures (EGT) are largely unaffected at recommended water / fuel ratios.
23. The cooling of potential hot spots in the combustion chamber defeats pre-ignition, the most destructive form of uncontrolled or unplanned combustion.
24. Higher static compression ratios will require a higher percentage of water or water / alcohol.
25. No, water does not burn. We are not combusting the hydrogen in the H2O.
26. At around 13.2:1 or fuel air ratios of .75, EGT’s will peak.
27. Ferrari suspended water in their fuel during their 1980’s Formula1 period. We don’t recommend that you try this...although Acetone will mix with water.

This site is outdated, but it has some ratio info, too. http://www.motherearthnews.com/library/1979_September_October/Water_Injection_Wizardry

thank you for getting back on track. i'll have to get the parts and let you know how it goes. i'm guessing i can just tap into the vac tube on the back of the intake. i'm already running syn oil so it shouldn't be a problem.

You can't say it won't work unless you've tried.

The only part that seems hard to figure is the part about 2 pumps. Seems to me there's no room for extra components, but with an oversize pulley, you're gonna get more air flow from the pump.I havent tried it and I can tell you it won't work you will not have enough volume of air. and how are you going to drivr these pumps you most likely will lose hp not gain, hey dude try it if you want your time.

Antifreeze = ethylene glycol!
Ethylene = ethane with carbon/carbon double bond, hence suffix '-ene'
ethylene, methylene, propylene, etc., etc.
Glycol = Glycogen (glucose, as in sugar), derivative, with a hydroxide ion, making an alcoh-ol/sugar - 'glyc - ol'.

I know you don't know organic chemistry. But I'm sure you know chilton's, and hayne's. I'm takin' for granted you know how to read, and if you've noticed, they both say don't allow antifreeze to puddle where dogs and cats can be drawn to the sweet smell.
And as far as the kidney stones from inhalin' antifreeze? Tell some soldiers who've driven hummers with leakin' coolant that you don't get kidney stones from it.
I have to keep reminding myself... It's better to have to put up with ignorance, that to be ignorant (I think).

Of course, maybe I'd better humble myself a little... My doctoral dissertation WAS rejected (on a technicality).

Just wanted to add:

The reason they say NOT to allow animals and suggest that humans do not drink it is because when the ethylene glycol reaches the kidneys, they start to break it down into ketones and further reacting to produce aldehydes. They only way to save someones life that has consumed an apprecialble amount of Et glycol is to administer near toxic amounts of ethanol. The reason this helps is because the ethanol in higher relative abundance to the Et glycol will be broken down instead, allowing it to leave the body in the urine before being turned into aldehydes.
