I know everyone is taking a beating from the sun this week. In extreme heat such as this, would it be wise to pour water into the intercooler? I believe the STI has this feature built-in. I should be okay, right? And I was using Poland spring if you're wondering. haha

Emm... Not into but unto

And not a good idea on the RDX because the water will settle in/on the spark plug area!

Thanks for catching that. I wanted to say onto.

I almost for forgot about the sparks plugs. Luckily i didn't empty a gallon of water, just half of the 16oz bottle.

Uhm... That precious water would be much more useful inside you and not on the engine! The RDX can handle the heat just fine. If anything, doing what you did could cause extremely hot components to contract quickly and cause serious damage. Drink the water and leave the engine alone.

just make sure you have good engine coolant in there. factory is fine. and ofc synthetic oil. if you are really concerned about heating avoid idling. faster you go better it cools engine.

Haha! That's a good one! No, Really look into cryo- system, like nitrus express. Works by using CO2 nozzles that mist the cooling fins on the intercooler. You could do a waic system, home brew, that's what it sounded like... Ingesting water in the intake sounds bad to me

Guys the op made a mistake when he wrote 'into' the intercooler; He meant UNTO!




And on that note, water/methanol injection is an option worth considering

i wouldnt pour it onto or into.. as funny as it may be.. a fire extinguisher (sp?) would work better.. if you are looking for a quick cool down.. the reason i say no water is cause it will still get into places you dont want it near and can cause issues..

make sure the extinguisher is the nitro filled ones.. and you should be good or you can go to an electronics store and get a bunch of air can cleaners turn them upside down and spray on the intercooler.. that would cool it too.. but as mentioned above your RDX can take the heat so i wouldnt worry too much about it.. make sure it has oil,coolant and you are good just dont drive it like you stole it and it will be fine

I see why there wasn't any trends regarding this issue. I don't want everyone to think I'm pouring water every time its hot out. It just occur to me that the STi had a built-in feature that you can spray water unto its intercooler with a touch of a button. I did not, by any mean, pour a gallon of water unto the cooler. I hope I didn't give any wrong impression of abusing the car.

Lol....Its probably just that alot of the people on here are not tuner types and didn't know what you were referring to ----> intercooler sprayer

Intercooler Sprayer

90% humidity here does that for me for free xD

wspy, r34(fav car all-time) ic system good find, look at I think NX CO2 fog'er system for you!
Both cars! They have um in NO2 flavor aswell.

I remembered this from forever and a decade ago. Back then I wasn't interested in it.

Hmmm....looks like it could be a home brew'd system that wouldn't be too shabby. Personally I'd use some windshield washer nozzles, installed in the sides of the "channel" on the underside of the hood that routes air to the TMIC. Run the lines to a reservoir with a pump much like the windshield washer pump, connected to a soft button switch (maybe taken from that R34???) to activate the pump like pulling the windshield wiper lever activates the washers.

I like this idea, but would like a way of not "over spraying" and throwing too much water around under the hood. Other than "don't hold the button down for too long", of course .

well seems summer heat seems to have some effect. the quarter mile and 0-60 times were slowest ever. average was around 7 seconds, a full second slower than winter time. when it gets cool ill do some test again for comparison.

pickler

here are the numbers. car was in [d]rive (s mode revs to 7200 with hondata, d mode 6800). HP@wheel. temp 90'f, 60% humidity.




i'm not happy about the results but i did not launch, scared to overheat torque converter+ATF. VSA was on which explains the full second from 0-10. launch & s-mode can shave off a second?

here are my numbers from last year winter:

I should've look for the photos from the beginning. Thanks for posting the photos!

It would be interesting to see this tested by monitoring IAT w/o spray and then with spray while driving along at a set speed on a flat road.

Don't know about doing it with the i/c over the block though.

And it would be less effective as rpm increased, as the increasing volumne of air will spend less time in the i/c.

I would think that if Acura believed its intercooler ran too hot, they would have also band-aided the issue with a water spray...but they engineered it to not get too hot as to require such a band-aid.

DRR98

Not that "it runs too hot".

Attempt to make cooler.

The cooler the air going into the turbo is the denser it is.

And denser is better, in this case.

Would a front mounted i/c would be cooler than one mounted above a known heat source (engine and turbo)?

Revvvuupp

I know this is an old thread but what do you guys think about co2 sprayed on the tmic?

DRR98

Would scale build up on the fins?
Would the water contact the engine?
Where will the water contact the engine?
Could the water cause thermal shock damage on contact with engine parts?

Cooling before the TMIC might work though. Evaporative cooling.

At the front of the car in the TMIC air inlet- install fiberglass media and a feed water rail from above to wet the media. Capture the run-off water to a drain away from the engine.
