water injection

i remember those kits were popular back in the early 80's late 70's. the government got rid of them secretly cuz they were losing cash from gas sales. the clean air act of 1970 is a joke.
 
LOL!

Back to the question- Spearco sells WI kits, but I don't think that they are the most effective for DSM's. Check the archives at dsm.org. Lots of WI info there.

Water injection is good... but after reading about propane injection... it may cost a little more, but it's a hell of a lot better


Search the archives... you should find some great information about it.
 
If your gonna spend the money to inject propane, why not just inject nitrous and actually make substantial gains? At least water is free.

As far as water injection goes... I tried the spearco kit years ago. It was cheap and as they say, you only get what you pay for. A good system is aquamist. Do a search on a search engine, I do think they have a website.
 
You might want to pop onto the DSM water-injection mailing list, too, and take a stroll through the archives:

http://groups.yahoo.com/group/DSM_water_injection/

Lots of good information to be found there. Be sure to check the Links section (I think you have to subscribe to get at all that, but you can subscribe without receiving messages if it's really a problem); there are a few step-by-step build-ups for WI systems that might save you some cash rather than buying a whole system outright.
 
if i was you i wouldnt even think about water injection. sure it takes temps down on your car but your also raising humidity A LOT!!! which causes engines to run not at there best. if i were u id jus stick to a Front mount intercooler

ya but can't u run a lot more boost since it adds like 8 psi to ur gas???????
 
I run an aquamist 1s system with a front mount Spearco.

Yes you get what you pay for, yes it works, no it won't hurt your engine if used correctly.

Proof? ---> 12.4 @ 107 on a small 16g w/ 91 octane gas.

Enjoy :cool:
 
-Hey Nothing Stock, are you using the windshield washer fluid reservor or some other container, if using fluid resevor, how many miles between assuming that it activate via a pressure switch ? because the 1G's rear resevor is really small, I don't know if I should get a bigger tank, another question is how can you detune the motor in case of fluid is out? RRE told me that's better to get a bigger FMIC than WI b/c of the running of fluid deal. TIA.

Not sure how great this water injection system is, but Doug Derby ran 11.9@112 on pump gas without water injection a long time ago.

Yes, it's much better to get a good FMIC than WI. There is no substitute for a 2-216 spearco FMIC.

I don't use the washer reservior, I use a separate container. I go through about 1/2 gallon of water every tank of gas. YMMV

Listen to RRE, they know what they are doing.

93/94 octane is much different than 91 octane, and a 16g is much diffrent than a 20g.

Apples to oranges. I'm not saying my times are phenominal, but doug is a pretty top knotch racer. I don't want to come off sounding like an ass, but most of the guys asking questions in this thread probably have never ran a 12 second 1/4 mile. I'm just trying to help.
 
This thread was asking about WI, not Propane. Propane works, but N2O is a better setup. In my opinion if you have to go somewhere to fill up a bottle, I'd rather go to fill up an N2O bottle.

Yes, it takes temps down and yes, it increases humidity. That is the point! Look up the latent heat of vaporization of water. Do you agree the number is very large? With that number being very large, that water you inject into the intake sucks up a bunch of heat changing phases between liquid/water. This provides "in-cylinder cooling", something an intercooler cannot do.

Before just totally dimissing something, you should do a little research. Here, let me help. Try Aquamist's faq site. Try the root directory for tons of additional information. Water injection is a great idea, one I intend to implement eventually. You can safely run very high boost levels on pump gas with a properly tuned water injection system.

Oh, and one more thing. It is possible to achieve intake temps BELOW ambient with water injection, impossible with intercooling. Add to the mix the ability to super-cool the injection water or run water/methanol mixes and water injection has tremendous performance advantages.

Propane and Nitrous are two totaly different animals. It is like saying if you are going to get oranges why don't you just by apples.

Propane is a High Octane cold Fuel. Nitrous is not.

Nitrous is an Oxidizer. Propane is not.

Propane can be used as a secondary fuel source. Nitrous can not.

Propane can aid in an otherwise un modded factory fuel setup adding secondary fuel when needed. Nitrous Can not.

Propane aids in raising octane levels, lowering intake and EGT temps, and decreasing detonation. Nitrous certainly does not and can not do that.

Nitrous in itself adds power. Propane Does not.

Propane allows you to run higher boost levels safeley as you would on Race fuel. Nitrous does not allow this.

Think of Propane as Race fuel on tap when you need it. 110 octane injected cold fuel. But better than race fuel since you are not using it up just cruising and it is only costing about $2-$5 every 2-4 gas tank fill ups instead of $4+gallon for race fuel.
 
Real nice, take one line out of the entire summation!

Here is the entire post if you missed it
