Putting ice cubes / crushed ice on the I/C
#1
Hi guys,
Ok don't laugh. I am wondering how you guys keep the I/C cold before 1/4 mile runs etc. At our drag there is no where I can drive first to get the car all warmed up so I would have to let it idle for about 10 mins before I race. I guess I could leave the bonnet open during the warm up idle ?
Also, right before I race I have to sit in a parked line with engine running. I know the under bonnet temps will get very high. From there I hit the track and floor it......probably not the best for the engine. I was wondering if I poored ice all over the top of the I/C and let it sit there while I am waiting if this was ok to do and if it would help ? What do you guys think ?
Cheers,
Ray

On the Getaway in Stockholm dvd, there is a scene near the end where a someone sprays the FMIC of a Sierra(?)with a CO2 fire extinguisher! Guess this is pretty much what your looking at.

Ok thanks for the above suggestions; however, I am worried about their corrosive properties. Lets get back to the ice cubes. has anyone ever done this. Will it work, can it do damage etc ?

I was at at track day once and see a 911 turbo with which look like a home made cage just above his intercooler and when he went out on track he fill it up with ice. So if it good enough for him

I know someone on here who has NOS fitted to the intercooler which is obviously more controllable but I can't see why Ice on the IC would hurt.
Have you thought about aquamist water injection ?

Thanks guys.
As far as aquamist: I have looked at this option but want a few STI-7 owners to try them out for a while before I go this route. Also, the mappable aquamist is not cheap and I am not sure if anyone on this island could install it properly.

I've seen race up Porker 911 turbos with dry ice on top the intercoolers to keep them cool. I think one was the 650bhp Ruff conversion which broke the 'Ring lap record!!
Good Luck!

I know in Australia they (Tony Rigoli team IIRC) were putting crushed ice on the i/c ahead of runs on the strip.
There was another thread about this back in November I think.

Cruseed ice would be best, as you would have good coverage over the core, and when it melts it also turns to water, also covering the entire core for the duration of the run.
I have tried the freezer spray in the past....there just isnt enough of it, and it evaporates too quickly to be of any real use. It may be different in a confined space but not out in the open.
CO2, have seen it used on the Stockholm vid, but again, I think cold water/ice would be better, but havent tried it. Just not sure if they would be letting you cover the car with water before a run up the track, as it could leave wet bits on the main track, which may not be a good idea for some high power 2wd cars following.
It follows then that a cold waterspray on the IC would be good, and also use a lot less water, and could be controlled from teh drivers seat

Crushed ice would work ok, but you might get in trouble (i did at our drag strip) as it melts and then leaks on the track. Use dry ice or buy a nitrous system which are sold specificly for intercooler spraying applications. If they don't mind you dripping on the track then go for it. Another piece of advice is to push your car while you're in the line. Many people do it here (i'm too lazy) then start your car when you're ready to stage.
#12
blacrex, isn't pushing your car to the line just as bad becuase although it may not overheat the engine will be cold which can be just as bad, cold engine and then flooring it ?

PS: How about filling the I/C spray holding tank with crushed ice and then pooring water on it, that will give you an ice cold spray with no water leaks ?

RON, this was my biggest fear, that is why I posted this thread. I wonder which is better. Completely covering the top of the I/C with a very cold substance (lol...ice!) or putting some ice and allowing 'open' areas to blow the cold iced air through the fins ? Probably will be two schools of thought on this one, but isn't a completely enclosed water cooled I/C better than an air cooled ?

I'm fitting an Autospeed intelligent IC mister on my Golf - but will be using the standard washer tank and the headlight washer motors (now redundant). I've heard that a 50/50 water methanol mix is the way to go - because of the cooling properties of the methanol evaporating - can anyone explain/confirm further?
#20
easy...
inorder to get rid of heat it has to be physically removed. the water is good for this however, it takes quite a high temp to do this effectivly (boiling point). adding the methonol reduces the BP and allows for there to be a higher rates of cooling...
it can be a bit more technical, but thats the easy explanation...

hi,just read a relevant article in this months evo mag.the vehicle in question is a ford 150 lightning,basically the storage tank for i/c spray is wired into the air conditioning loop.resulting in a increase of 50bhp.............on top of the 500bhp!!!!

Bearing in mind I know NOTHING about this, but reading the thread with I hope some degree of intelligence, if dry-ice is allowed that would seem like the ideal solution for dragging, or rolling road days. Never mind if it partially blocks the intercooler, it will decrease heat-soak dramatically on the grid and on the move provide a nice cool charge. If/when I get my motor on the rollers I'll take some dry ice, if only to try and replicate the on-road intercooler performance.

Surely dry ice would not melt though, and soak down through the core. Whilst it may be very cold, when it 'melts' it turns to vapour, and simply rises into the amtosphere??
Crushed ice, would IMO be the best, and easiest option to get hold of.
I havent tested either, but just my opinion

Andy W,
I mentioned this in an early reply on this post. Seems like the best of both worlds. You get the fine mist and the ice cold temp water hitting the I/C. This is what I am going to do at least

Methanol can also be corrsive to some aluminium materials, and is generally used in water injection systems 50/50, NOT water spray systems.

What about crushed Ice mixed with water in the IC spray bottle, not so much as to run out of liquid water but enough to keep the water temp down.
Could washer fluid, Methanol, alcohol or methylated spirits be added to the water Ice mix to lower the freezing point and bring the temp down?
No risk of blocking the air flow to the IC which would be my biggest worry.
