didnt know where to post this so if i get barked on then whatev.. lol

i was just wondering to myself, putting ice on the plenum.. will it help noticeably?
i was at the track (1/4 mile) where this guy with a gto was doing this, i asked if it helped to which he replied " OH YEAH!"

anyone?

 

buy a fire extinguisher... it work wonders

what happen by spraying water on them?

ice ? hmmm

 

 

Noticeably? Doubt it. Can it hurt? No, so try it and find out.

Do be mindful of ice melting, don't let water run over wiring or sensors or the alternator etc. Cooling the plenum will never hurt the performance.

 

Does it work? Yes
Does it help? Not much.

At full throttle, air is rushing through the intake/plenum so fast it hardly has time to heat up or cool down. If the plenum is hot, it may heat by 1-2 degrees. If the plenum was near freezing, it would probably cool 1-2 degrees.

Would any of it be noticed by a steet car in a 1/4 mile run? Probably not.

 

I do the ice thing in the summer when bracket racing. Usually 1 hour plus between runs. You will also see other techniques such as:

Alcohol and water in a spray bottle.

Frozen gasoline.

Does it help much? I don’t know. I have lost races by 1/1,000 second. How much is much?

 

I do it. I think it does help in the summer months a little.

 

frozen gasoline?

how will that even work lol

 

so is there any way to cool the intake piping?
i mean think about it, if the entire pipe was cooled down and the plenum you might get temp down a lot.

anyone ever cool down their piping?
the reason i ask is because after racing my car my plenum was extremely heat soaked.

 

At full throttle, air is travelling up the intake tube at about 134 ft/sec. That means that it spends about 0.015 seconds in the intake tube and probably the same amount of time in the plenum.

Air is a poor conductor of heat so the only way to significantly cool it is to run it across a large surface that is very cold. You would need some type of finned heat exchanger (better known as a intercooler) with a lot of coolant (dry ice, liquid nitrogen, etc.) to be able to drop the temperature measurably.

Immediately you have the problem of additional drag of the finned heat exchanger restricting the air flow into the engine. Plus you'd have to deal with the extra weight of the coolant you'd be carrying.

(see where this is going)

If we shift temperature realms a little bit we can solve all those problems. You can overcome the drag and reduced air flow with a turbo/supercharger. By compressing the air, you also heat it so you can use a intercooler to cool it down again.

Another way you can make the air colder and more oxygen rich (the goal of cooling the air in the first place is to make it denser and carry more oxygen) is to go the nitrous route.


When I run mine hard, I leave the hood open for a while to allow it to cool down before the next track session/autocross run.

 

as do i.

so i see where you going with adding the extra weight, but with the increase in power that youll get it will outweigh the weight? anyways...

an idea just popped in my head.. lol
what IF there was some was of making a sort of mini inner cooler for the airbox/intake.
see what i mean?
let me try to edit a pic...



obviously i my editing sucks more than anything but the idea is what counts.
has anyone else thought of this?
it would most likely be a home made thing but still!

 

I used to spray my top mount WRX intercooler with alcohol. I wouldn't do it on an N/A car. You could always look into the DEI cryo kit. It can spray CO2 on your piping or your fuel lines. Again, not something I would do. The best way is to spray nitrous into your intake. Works wonders for cooling and making power...
