Hello, I've been told that AEM's Water/Methanol Injection kit cannot be applied to RX-8. But last week I saw it on one. Is there really a way to apply this to 8s ? (Without FI)

no reason to.

Why would you believe a Water/Meth kit couldn't work on a RX8?
Water/Meth on a NA RX8 is really not going to get you anything in terms of HP.

LOL well do you remember that one dude that was using it to help clean the carbon out of the engine?

lol..one should not spray methanol for engine cleaning unless the plan is to clean the carbon off by eating the aluminum it is on top of. haha

water by itself for engine cleaning, okay. but seafoam works so much better and is much, much cheaper than the w/m system.

reducing IATs with methanol, that could work, though not neccesary in NA form. one can argue reducing IATs is never a bad thing I suppose.

Ok, got it. So its another waste of money without FI. It seems Header and Straight pipe is the best way to gain some hp for now.

^only if you use a well made proven design. even then it is not much

I suppose you could run lower octane gas, and use the methanol's extra octane when "on it".

The bad news is that the water methanol mix costs way more than the gas does.

+1

Remember you are displacing gasoline to add water and methanol which doesn't contain nearly as much potential energy.

I bet you would still be losing power.....

So it is worthless on na 8s'

Hey guys ( :

So... AEM Water/Methanol Injection Kit — This is a bad idea for atmospheric engine RX8?

What about summer? And an attempt to lower the air temperature? And increase the amount of air in the combustion chamber?

Not in my opinion.
You’re still displacing more air for any kind of increase air charge density because of the cooling effect.

But if you’re itching to do something you can try something from these guys

I do not strive to do —> something <—

Do you know about the injection of water into an aircraft engine ... during the Second World War? It was one of the basic simple ways to boost the engine.

Heard something about this?

I have, tho I can’t say I’m some sort of historian on the subject.
I’m pretty sure those engines where super charged or turbo charged.

Nonetheless I will hit the google and refresh my Aviation history.
Aviation stuff is cool

Yes those engines were supercharged. MW50 or similar systems were an emergency measure, to run increased manifold pressure for a short period of time. So it didn't actually boost anything itself, it permitted higher boost without destroying the engine. There is nothing to be gained from this on a naturally aspirated ground vehicle.

Thanks Loki,
I had some fun looking in to the aviation side. As you mentioned, I couldn't find anything that said Water or Water/Meth was used in a naturally aspirated engine, everything had to do with a boosted solution.
This clip here will take you straight to the part in a video on "Why was the BF109K faster than the P51D? MW 50!" (as mentioned by Loki) where the commentator mentions a research paper using only water in a non-boosted solution

Another great video on water only vs. water/meth vs. meth only for boosted solutions on a rotary!

My sources talk back, the engines were naturally aspirated .. But yes .. the injection was used for afterburner mode.

I'm wondering if someone tried to play with this at a professional level?

Thank you for your interest in the topic I raised. (:

I saw different experiments with water injection into the combustion chamber .. Because I thought that maybe someone had experimented with a rotor and water injection without a turbine ..

I think each of you ride when raining there is moisture in the air .. By my humble opinion, each of you felt a slight increase in power, but noticeable by "butt" .. (: And now I'm wondering if it is possible to achieve the same effect during the summer heat by injecting a small amount of water.
Because you know how bad the rotor is, and any engine when it overheats or heats up more than it is comfortable work +20C air temperature .. ( :


AND YES! I'm talking about a mixture of methanol and water .. Not pure water! Sorry ( :

Now I’m confused.
I think we are dealing with a language barrier.
So with that … good luck.
I hope you find what you want

I would not listen to those sources any more

You're welcome to try but it will not have the effect you want. Water/meth lets you run more timing or more manifold pressure without detonating, it doesn't produce its own power. If you need more cooling, cool it through the radiator.

Ahaha! Sorry. It was late and inattentively answer .. Slightly corrected .. ( :

At the moment I ordered a RE-Amemiya hood. It's very hot here in summer, I think it should help remove heat more efficiently.

Anyway, thanks for your attention. ( :

— Hi (: Maybe it will be interesting for you .. about water-methanol on a non-turbo engine.

— Interesting tests .. May interest you.

Those are interesting thanks for sharing.

That first video of Horse Power tv or whatever is a giant infomercial so you need to take it with a grain of salt.
First thing you can’t add that much timing to a rotary engine.
Well not safely, zoom zoom boom.

That bench engine likely had great knock sensors in and they advanced that timing all the way until the torque was staring to drop. Again you can’t do that so easy with a rotary. Advance the timing to far and get a knock event and it maybe too late.

Second I will bet you dollars to donuts if they ran that much timing with the race gas setup as the did with the street gas and SNO kit it would have produced as much or more HP.

None the less it was a good watch thanks again.

Hah (: I don't trust this material, that's why I share to discuss. (:

My new engine went 70K and died a couple of days ago. Apparently overheated and stayed abruptly in a heavy downpour. BUT .. no one will say for sure ...

At the moment I am in search of a new engine.

Communicated with: Chips, Pettit, IRP, REC, Mazdatrix — The last two are the most adequate.

Maybe you have a proven supplier of new or well tuned engines?

Meantime, I am preparing for a new approach to the 'project" ( :
