I just had my Cooling Mist Water Injection set up installed by Tri-Point Engineering a few weeks back and my car is driving like a dream. I have only been using 100% distilled water in the tank as that is what it was tuned for.

I have been looking at the pros and cons of methanol/water injection and have found this Boost Juice product from Snow Performance in CO. which is 51% distilled water and 49% Methanol.

My question is, if i buy this Boost Juice and pour it into the water injection tank do I need to retune the AEM EMS on the Dyno because of the added Methanol content?

you "could" but you need to make sure you have enough failsafes if the WI fails.

I ran an autox when at the end of the last run noticed my AIT was higher. What had happened was I bumped the on/off switch to off and never knew it.

If you do plan to tune for the additional fuel, you need to have failsafes in place incase the WI fails or you will lose the engine. I think Howard Coleman is the only one of the forum who is doing this properly (search for his name). Otherwise most are using it only for detonation prevention.

stevemack

Yeah, I am using it for detonation prevention as well.

My Cooling Mist set up came with a clogged nozzle detector and clogged nozzle LED to let me know when it is pumping water or clogged. I hope that is enough fail safes.

I would rather not tune the engine again as I don't want to get a large amount of extra power. I just want whatever extra power the methanol will give me without blowing the engine.

I am done adding extra fuel until I get the 99 spec twins. That is the next time I plan on getting it tuned and hopefully Steve Kan will be in the area to tune it for me.

I run windshield washer fluid through my aquamist system. It contains water and methanol

stevemack

What brand do you use?

Are there any additives in it that would damage our engines or the WI systems?

Would I need to retune the AEM EMS if I choose to run the washer fluid instead of the distilled water?

what did tripoint charge you for this system?. did they do a good job tuning the car.

Any brand I can get my hands on.

No additives that I'm aware of---ww fluid contains water, methanol and ethylene glycol (antifreeze).

Jack here on the forum has been injecting ww fluid on his track FD for many years with no ill effects.

As far as retuning, the methanol may affect things a bit. I have not been tuned for my water inj--I am using it as a safety net.

Just check your filter from time to time. I went with a different filter (for fuel) than Aquamist sends and it became cloged, had to soak it in vinegar to clean the filter . Burned out my motor, however was easy to repair.

Jeff,

It seems that Reggie at Tri-Point did a good job with the tuning. Mark had told me that he went to AEM for a seminar on how to tune with the AEM EMS and it seems to have paid off. My car has never run better. They now know what they are doing when tuning with the AEM.

Here are the prices for the WI set up.

Cooling Mist Deluxe Single Stage Water Injection Kit GB ~$400

Install WI Kit @ Tri-Point $425

Dynapack Tune after WI Install. $350

Hope this helps.

I've been hearing alot about this system and I want to try it. I'm want to run 25psi on the street with pump 93 octane. How are the results. Is this safe to beat the living **** out of it constantly?

I don't think '25 psi' and 'pump gas' should really be mentioned in the same sentence with regard to boosted rotaries. No, it's not safe to beat the living **** out of it constantly under those conditions, water injection or not. For that boost level, run c16. It's not cheap, but neither is blowing your engine to hell either

The methanol is gonna screw your afs's and may give you ign break up at high end. I would stick to the water only unless you wanna re tune it.
Meth and water will help to keep the temps down but methanol really needs to be fully exploited to be worth while

Did you know that Glycol from your screen wash is 11 times thicker than water and will actually increase your chance of det.

Scott,

Thanks a lot for your input. I didn't think it would be as easy as dumping in the Boost Juice or WW Fluid to get more gains. I guess I will just keep using distilled water until I can get it retuned. Hopefully Steve Kan will be in LA sometime soon.

The boost juice is good and because it's pre mixed you never have to worry about different % of the water meth mix. Once tuned for water meth mix you won't regret it. Also snow sell safe injection system as a really good fail safe.
