Funny what sticks in peoples minds- What stuck in my mind was David Buschur himself came on the board and said No Way In Hell. The enginge was ingesting the N2O from the intersprayer- you would kill for 50 HP Why spend $350 and shoot it into the engine- thats how the intersprayer made its power

Don't try this at home boys and girls. It WILL burn, but with an invisible flame.

Sorry to be negative but denatured alcohol is flammable. I've got a can in the garage that states in no uncertain terms that the contents are flammable. Denatured alcohol is simply ethyl alcohol that has been "spoiled" or it's methyl alcohol. Don't try to drink it either.

 

So does anybody have a comment about my Prestone De-Icer Fluid as a IC Sprayer liquid? Would it be a good thing to have during the Winter? Just wondering.

 

so my being smart and all, grab a pop can and cut the top off
and pour about 1/4 cup of heated denatured alcohol in it.
go on outside and drop a match in it....

fizzle

2nd match

fizzle

4 matches at once

FIZZLE

rest of the book
pretty flames till I dropped it in the can of acohol

splash fizzle

 

Now fine mist that same mixture

 

that was hard enough work, I am going to spray water/alc
in mine when finally get a turbo in it.......
the way I figure it is people have been using it for 20-30
years now, if it was bad im sure they would have quit by now

 

Exactly my point. Which is why I said to the others to either join the topic of stop hating and shut up.

 

We're not hating, we're offering a safe alternative that isn't flammable. Until you prove ON A DYNO and not an accelerometer that your car is making more power with a water/Isopropyl IC spray mix, you're just spreading rice math rumors to everyone and convincing them to put spray a known flammable substance onto their intercoolers.

 

Everything you wanted to know about the safety of denatured alcohol can be found here .

Oh, here's the MSDS for common windshield washer fluid. Sorry, it's a PDF.

I'm not hatin', just spreading information as I see it. Take from it whatever you want. I'm going to stick with the 30/70 mix of alcohol/water mix found in windshield washer fluid until someone has some hard evidence in the form of IAT before and after the intercooler.

 

Amen

 

I am using 90% Isopropyl Alcohol OK.

A 50/50 mix will not burn. (alcohol/distilled water)

A 60/40 mix will not burn. (alcohol/distilled water)

There is nothing wrong with using Isopropyl alcohol on an Intercooler:

Washer fluid is using this same mix, only with coloring and other chemicals.

I have know other racers to use special intercooler spray mixes or unorthadox cooling methods. Ice/alcohol/co2/ect. Cooling the intercooler makes more HP.

I am simply offering a do it your self mix that is clean and effective.

Before you guys acuse me of spreading, "rice rumors".
Read up on your facts.

Stop the flamming and give the board ideas on the intercooler spray.

 

Water does a better job at cooling an intercooler than alcohol. The only reason that alcohol feels cooler on your hand is because alcohol evaporates at a lower temperature than water. But at speed, the airflow over the intercooler, and the heat of the intercooler is more than enough to evaporate either alcohol or water.

And water, given its higher latent heat of vaporization WILL remove more heat from the intercooler than alcohol will.

 

Shape you cant talk to this guy links have been provided chem people have given examples he simply thinks hes i right and thats the problem with this board is low level intellectuals spewing misinformation and not being able to process data properly when it is presented. He has the"ultimate" mix he says and unfortunately there will be people who believe him

 

I think you are the one that is most likely to be accused of flaming. You have come on a bit brash and outspoken. Some of the guys are just commenting on their thoughts as to the effectiveness of this or that. I understand that it can be a bit frustrating, so I will give you my own thoughts. Let's chill a bit and talk about the whole waterspray system in a technical manner.
I have personally designed a waterspray system for WRX's (which are more in need of it than EVO's) and everyone seems quite happy with them. Waterspray is proven to yield improvements with an intercooler that is somewhere close to it's limit in terms of steady state heat exchange. That means that the primary heat exchange method (intake air to aluminum) is steady state and the secondary heat exchange method (aluminum to ambient air) is at it's full rate of exchange for the situation. This occurs once the aluminum finds a new, higher temperature. I have found that regardless of the water/alcohol mix, the nozzles and pump design are more crucial. If you attempt to use windshield washer nozzles, it will be sub-optimal in terms of evaporation. Ultimately you need it to evaporate because of the latent heat of vaporization. "Cutting" the water with alcohols assists in the vaporization process but reduces the net heat exchange in the process. That is why you must find a balance between using more water for better heat exchange and more alcohol to assist in vaporization. That being said, using more alcohol is somewhat of a bandaid to assist when the spray nozzles and pump pressure are not as good as they could be. A finer mist yields more liquid droplets and finer droplets. The ultimate effect is greater surface area between the airborn droplets and the air. Each droplet also has a lower total endothermic requirement to evaporate and make room for the next droplet. If you don't evaporate the droplet before it hits the intercooler, it will have a lesser chance of providing optimal heat exchange levels. In the process, I believe that the secondary heat exchange rate can be lessened a bit since you now effectively have an aluminum to water intercooler instead of aluminum to air. You are essentially drenching the IC in water. As this builds up, the possibility of the surface water evaporating declines rapidly and so does the effect of waterspray.
So ultimately, the first thing any EVO owner should do, IMHO, to improve waterspray is to use a better pump and finer nozzles. I sell such things in kit form for WRX and in individuall component form for DIY'ers. That being said, I am not trying to sell a kit (otherwise I would have just said; "Hey, I sell those!") but rather to help the EvoM guys understand waterspray systems a bit better.
Even with better pumps and nozzles, sometimes it still needs a bit of help in evaporating; that is where alcohol or something of that nature can help "fine tune" the setup of the waterspray. Finer mist is always better but the ratio between water and alcohol will depend heavily on the conditions. Ambient air temp, heat soak of the IC, steady state power output and heat loads and vehicle speed. There is no one setup that works the best with respect to ratios; it will depend on the conditions. A WRC EVO in Africa running massive amounts of torque out of a restricted stock turbo is running very high "duty cycles" of power compared to street machines. It is dumping heat into the intercooler at a drastic rate. On top of that, the ambient heat levels are very high and the air (in this example) is very dry. Dryer, hotter air will benefit more from waterspray and also be able to utilize a higher purity level (% water) for the W/S mix. If the vehicle speed starts to drop (in a few low speed corners) the IC is already so hot that it can assist with evaporating any excess water that started to soak onto the surface of the IC.
Well, anyways, that is my little technical comment section on waterspray.
On a street EVO, I personally recommend that once you upgrade your FMIC, you remove the IC spray system so the pod filter can pull air from the now gaping hole into the bumper reservoir as well as the underhood scoop (if it is still present). Ever wonder why there was an inlet on the side opposite the oil cooler? I belive this has a greater effect (steady state) than the waterspray system.

hmmm I agree with Mark. I want to log some inlet temps with that opening exposed.... I would like to assume that fresh air would then be directed at the intake itself.

Again Im just assuming because I have yet to even log inlet temps before and after I spray the Icooler...

BTW - Buschurs IC looks mighty nice..............
