water injection hobo style

Anyone tried this? Sounds tempting; might try it out on my NA 940.

Bad idea? Good idea? I swear I read a post about it ages ago.

[Acid8000]

Just readin it makes me wanna do it. Would you need to have it a Carberator? Dont think so.. Could just run a line from the intake manifold.... Hmmm I may try this on my carberated 77'. Would adding water to the Intake present another place for Rust to catch?

[slowmotion]

Nah, as for rust, I would say the water would be vaporised almost instantly.

I'd say it would work for injection too. At least I hope so; that's what I plan to try it on.

[MetalgodZ]

There's some good info on that page, but the site also contains some downright untruthful info.

I doubt that this would make very much of a difference on a turbo car, and correct me if I'm wrong but our NA cars don't need this in stock form.

I'm still going to do it, just for kicks, but I don't think it'll do a damn thing.

[benflynn]

why would you want this on a na?? and i wouldn't waste my time on a turbo

Any time you encounter detonation under load, water injection can help.

I have noticed a dramatic reduction in detonation events (via knock LED) since installation of the water injection on my car.... actually a 50-50 mix of methanol and water.

yes, it works.... very well in fact.

For NA cars, it would probably have more of a benefit when it came to high compression motors.

I'm thinking very seriously about following your lead in this area.

[kenneth rigney]

I have that on my 242, my dad gave it to me said it was an old hotrod trick, I won't drive the 242 without. I fitting it to my 164 already. MUCH GOODER!

you obvisouly havent tried it.. i ran it on my basically stock 940 and it let me up the boost about 7 psi on our **** 91 gas in cali and gained me about 40-45 hp and 50 ft lbs torque with just taht on stock exhaust and everything else.. it makes world of diffference

[brucepick]

Consider using distilled water if you want to run this for a while - avoid mineral deposits.

Remember, this technology is from the '70s (OK, argue with me, it's OLD) when a car that went past 100K miles was exceptional.

[speedn_j]

could you fill the bottel with seafoam or injector cleaner for a engine wash?

Agreed on the distilled water, but the technology goes waaay farther back than the 70's. It was being used on fighter planes back during WWII.

Add Alcohol. If its clean and claer and won't leave residu in the bottle it worth a try. The water will keep the engine cleaner on it own. I used diffent things at first, I stick with water and a little alcohol.

on my K-jet car, I just ran it the tiny nipple on the intake manifold, it is a minute vacuum leak. No problem. I should have piped it into the vacuum advance.

I know, and I probably should have been more clear:

I doubt that it's going to make very much of a difference to most of our NA members, since it seems that people prefer to go to the dark (turbo) side before they tear a block apart and start building for higher compression.

I'm planning on probably running water/alcohol injection at some point, because I'm HOPING to be running higher than 10:1 on a redblock at some point fairly soon.

[slowmotion]

So my na B230FB would be a good candidate? I never bothered thinking about +T because of the high compression (scandalous!!).. so anything that helps is a help. Or a waste of time. Either is fine with me.

We don't get Seafoam in Australia (afaik) but wouldn't injecting that create a lot of smoke? I know I've seen some pretty funny pictures on this board of people using it!

How about acetone + water? Or would that start eating things?

I'm gong to say maybe. You'll want to experiment with nozzle sizes, etc. I mean, why not... for $50, you can build your own... go for it.

acetone has a wicked high vapor pressure... I have no idea of it's use in combustion engines, but I would probably steer clear of it.

Thanx ripper!

[linuxman51]

i picked up a used intank fuel pump from some sorta chevy (looks vaguely like a walbro actually) for $7, when i get enough time together, its going to be rolled into a methanol injection setup for the 16v, that stuff is nuts on cooling the charge down.

[the poi]

the b6304f+t is gonna be sucking down methanol+water like no tomorrow. 10.7:1 compression? pah!

You've gotta be kidding me. Both Josh and I have run 10.3 compression turbos with above 15psi boost just fine. Well, I blew my engine, but I've blown lots of engines.

kenneth- you ran this system in a k-jet? care to explain a bit more about your set up and what type of benefits you got?

My dad gave me the bottle, I think its from a Bendix brake system from a semi-truck, mine is molded and came with a mounting bracket. I have a breather filter on the bottle and ran plastic brake line with a oneway valve to a tiny nipple on the intake manifold. Simple simple simple. like in that web site. The car accelerates better runs smoother. i took it off to zero in the idle and could feel the differance. One is going in my other NA car, maybe put one on the Neon too. I will ask my dad were the bottle cam from. The oldman says the water take a little room up in the combustion chamber and make the fuel burn better. I like this mod better than my VX cam, no $#!+.

i don't mean water injection in general, i mean this kit. i can see the light fellas
