as for the steam cleaning benifits - rob golden of pineapple racing talked for awhile at 7stock about cleaning carbon out of a rotary by pouring water into it while running. says its been done for a long time.

I love it when people attempt to talk **** and end up looking like a jackass. I'll break it down for you; water (Dihydrogen Oxide) being "injected", not sprayed around, over, or on, but injected in to the intake tract. Do some research before you attack a respected contributor to our community next time. Actually, you should just "pm" me your statement next time and I'll proof read it to make sure you haven't stuck your foot in your mouth.

Jesus, I’m starting to sound like Jim.

Yep, using water to clean the engine is an old trick.

Chill out!

If the person starting the thread would have clarified in his original post what he was attempting to do as opposed to being vague, then half of the posts made to this thread would not have been made.

It appeared from his original thread (to me at least) that he was attempting to add a waterspray setup (like you would do to a intercooler).
I am certain that many readers of this thread believed this to be the case also.

I apologise for trying to "take the ****" by posting a comment like "What are you gonna aim the water spray at, the radiator or the oil cooler (or both)?"
This was purely done with sarcasm and jest.

I am quite intrigued by this concept now that it has been clarified since I have very little experience with rotaries and welcome the wealth of knowledge this forum has to offer.

Lastly, sorry I didn't PM this post to you first to proof read since as worried I am to "putting my foot in my mouth", I am more interested in "putting my foot up your ***" for hating.

(I'm kidding with that last line, so take a chill pill and relax.)

Not into hating, I just want educating.

For what its worth, it was worth the laugh.

I apologize for jumping your ***, it was late and I enjoy being a smart *** just as much as anyone else. Don't worry, I still love you.

For the most part, I'm just trying to up my post count. People who have been registered for a month have more posts the me. I even stop by every day, just haven't had much to say. The forum has been getting good lately though, I have been spending more time here than the RX7 website, never thought that would happen.

Always enjoy your posts silverFD. Very informative when you aren't flaming the other posters

I feel you bro' :o

Hi,

I did not write this thread as an attempt to educate anyone on what water injection is. This thread assumed that the readers were understanding of the concept. I understand that alot of you dont know what it is, but thats a topic for another thread. So the "vague" nature of my post was obviously lost upon those that know what water injection is. there is a wealth of information if you just google it.

Thanks.

For what it's worth, we ran 50/50 water alcohol injection on the P-51 Mustangs at Reno. But then again they ran 45 psi in the manifold. This is also covered in Recardo's book.In his book it is very well documented through testing you could never afford to do.

way to go.

it still doesn't do a goddamned thing.

Nothing does anything for the Rx-8

But, someone does something for the RX-8! :D

Just add water! Or not.

army_rx8

hmm now if only you could add anouther 654cc....hehe or 2 lol ahh opps sorry i was dreaming out loud again.. lol have fun with your endevour..i know i have a blast with mine...hmm sometimes it's good sometimes bad...but you never really know until you try.

Resurrected from the past!

How did it go?

Did anyone read the article by Bryan Smith of RotorSports Racing, Inc. in the Volume 2, Issue 2 RX Tuner magazine on page 42?

Wouldn't the water injection help the poor guys in Vegas?

max5roadster

Perhaps...
Water injection has been used to good success in the miata community for sometime!

I'm still waiting for the "I'll post the results" part. Steam is a well known source of power; railroad train engines used it for about a century. I don't know how you'd do it on the Renesis since you'd have to install the injectors after the MAF, which means the ECU wouldn't know about right? Not sure that's a good idea. These new "everything controlled by the computer" systems are not at all like the old days; not so easy to tinker with them.

id like to see a meth inj. kit with a greddy turbo and interceptor-x....anyone have the money to be the guinnea pig on this?

coolingmist

Wow, Im amazed this thread is still going. After reading the negative replies on this forum I just gave up on replying. Jason carries our products at www.rx7store.net if anyone is interested. For N/A cars our systems are exceptional for eliminating ping/knock and allow you to run lower octain/more timing. If you have a heavily modified n/a car you will gain some power also.

We have seen turbo cars gain from 15 to 87 HP withour kits. Our dealer in New Jersey was able to get 87 HP out of an EVO with our kit. Closer to stock EVO's gained 25-27 HP.

Good luck to all of you with turbo's and Superchargers. We are debating on puting a turbo on the Rx-8 or Selling it and turboing a Miata.

Regards,

Coolingmist

coolingmist, i think you would have an easier time selling your kit if ou could produce a dyno of your kit along side a greddy turbo. Add an interceptor-X to the scenario and shoot for 300+ rwhp and I think you will find that you can't make enough kits!

Carnot and the Second Law, me thinks, would argue otherwise.

water injection is a nifty idea but it doesn't work well with NA petroluem fuels. Diesel and FI and hydrogen are where it's at. with injection on those and the increased temps, you can get a significant boost since the water can expand to 1700 times it's volume and it does so gradually ( not instantly like NO ). It has to have either tremendous pressure or heat or both to do this though, and NA cars run too cool to do it.

I have got to disagree. The expansion of any gas in your (NA) engine is a result of the heat that you get from the burning fuel. So in the best case, wheather you expand air + burnt fuel or air+burnt fuel+water vapor you are limited by how much your temp differential is. (Gas, wheather it is air or water vapor, expands the same assuming ideal.) Worse is that you now have to put enthalpy in to change liquid water (spray is still liquid) to water vapor; that means your water stole some of your heat that you were going to use to spin your rotor. Thats bad. Not good.

In a FI, water spray, holds your charge temp down for the same reason it "steals" temp during combustion (phase change from liquid to vapor.) The result is you can pack more oxygen into your charge and,... presto zoomo... you go faster.

Yes, I realize there are other applications of the intake water spray. I am just refering to the "steam is a well known sourse of power" sillyness. Same sillyness that made that movie with Keano Reeves and Morgan Freeman on the U of C campus unwatchable. What what it called? Reaction something.

And NO is nitric oxide. It makes your blood vessels dilate and contributes to ozone pollution. Pfizer made billions off of it (or at least a biological pathway related to it) with Viagra. NOS is N20. It makes you happy. For multiple reasons.
