intercooler sprayer

[figgie]

Two words!

THERMAL SHOCK.

Using NO2 or CO2 will cause stress cracks to in the aluminum. Not only that. If you go to the drag strip. Not legal due to co desation run off to the track. So keep that in the back of your mind.

Not to mention oxygen starvation from Co2 in any intake track.

I'd avoid added humidity too from water IC sprayers while boosting.. but cannot be convinced unless I see some data.

the smax intercooler has internal coils that you run N2O through and it cools the air from the inside out... no N2O ever enters your intake in ANY way possible. it is the best way to super chill your intercooler withouth the risk of sprayed gas getting into your inake and causing posible damage

Now that sounds interesting.

I'd stick with a good Methanol injection kit. I drove Ken Blakes 589 RWHP Methanol injected MKIV and I gotta say his setup is the way to go. He has a 5 gallon meth tank which will last him 1000+ miles, depending on how often he puts his foot into it since it only sprays when boosting over a certain PSi. Meth is cheap too.

 

[MK3Brent]

Agreed. Been meaning to check out the aqua-mist brands too.

well i posted a good cheap kit but i'm telling you the smax intercooler is a sealed system form what i believe

like i said there's that meth kit i posted and the smax is made for you to spray CO2 or N2O into it in a sealed system... it never reaches your intake at all... it works just like an air condition coil.... it just gets really cold on the coils inside of the intercooler... similar to this http://www.suprasport.com/S-MAX-Ice-Tube-intake-air-chiller_p_5428.html

but i'd never use a direct CO2 sprayer onto the IC if it ever gets sucked into your intake it can do real damage

honestly all i can say is do some research on the smax ... they really did their homework on those intercoolers

Pulling cool intake air from underneath the headlight will probably drop your intake temps more than spraying the IC with water.

 

[Steely]

every little bit adds up

 

[Steely]

sorry it isn't a closed system... the exhaust side of the intercooler vents to the atmosphere on the outside of the car

i have no2 spray for just hot track day's as in between runs

This is by far the most cost effective way to keep the intake temps down. I see so many builds where people have the air filter close to a heat source. If your pulling in ambiant are of 60*c from under the hood your making your IC work harder to bring the temps down. By putting your intake behind the headlight you should be pulling in air at 30*c or less (depending on where you live) so thats 30* less temp the IC has to deal with.

Guess what the OEM setup does????

 

[NashMan]

i think every car that is made is done the same way as well

there isnt a gain in hp but in the summer time it well keep your air intake temps down. now if you were to use a co2 or nitrous sprayers then u might see a gain in hp. im nt looking for hp gain

I'm personally not a big fan of using gas to spray the intercooler. It sounds dumb, maybe risky, and definitely expensive. Spraying nitrous on the intercooler is dumb and a waste. CO2 can do the same job, probably for less, and is more commonly found.

Either way, water probably does almost as well and is far more plentiful and cheaper. Its also safer, and probably easier too..IMO water is the best choice.

Spraying N2O in the intercooler is also an idea, but not as good as a straight up direct port IMO. I personally dont care much for nitrous because it has a whole new set of risks that boosting alone already has. Most of all, its another fuel source to refill in addition to pump gas. I personally would only consider water as a supplemental source, and nothing else.

1 of my buddys did a few runs on the dyno with using a sprayer kit, of course the nitros had a small gain because after going through the intercooler some was sucked in through the intake.... C02 had a reverse effect, the car actually lost a few hp, and like others have said, it could damage your engine....


a meth kit might be the best route and isnt tooooo expensive... i am looking to go this route myself soon...

also using the windshield washer fluid on the intercooler isnt bad for it as long as you are moving....

just my .02

It's hard to say which is worse: cool air that doesn't flow as much(OEM). Or a high-flow of blazing hot air directly off the radiator! (Like every single MK4 out there)

I think one of the vendors here sells a bolt-on cold air intake kit. Much easier than making your own, like I did.

I was thinking of making my own heat shield and using one of those headlight covers with the vent.

careful!

remember who you are talking with...

How exactly do you know that the OEM filter + housing does not flow? If so when does the housing reach critical velocity or does it even allow the air to achieve critical velocity?
What is the pressure delta of the OEM filter in the OEM housing? Same Q with the aftermarket?

I'd love to know that as well, but I will say this, after installing my intake and hardpipes (had to get an intake as the stock airboxy no longer fitted) the gain was noticeable.

The stock airbox doesn't look like it would flow very well considerly the air isn't funneled in (it's got a wall around the opening).

Anyone got a flow bench that would test? LOL

Anyway, back to the question at hand. As already mentioned CO2 in the intake will drop power (from what I've heard it was an old trick back in the day to have nozzles aimed at the other lane at the dragstrip), and N2O is expensive for such a small gain (you'd get more with it actually IN the engine, though this depends on the class you're running!).

Using any kind of liquid would be BAD at at the drag strip (water on track = BAD). The same effect is often gotten by spraying the IC down with a CO2 fire extinguisher. All you have to do it get it really damn cold and then do the run, spraying throughout the run would be pointless and dangerous to the tune (as already mentioned).

Now, the CryO2 intake cooler would be interesting to test...

They certianly arent cheap though considering what they are and the fact you need the rest of the system with it:

They're usually used in combination with an IC sprayer because you gotta release the CO2 somewhere anyway.

I always thought those were a neat idea, but I'd bet that water/meth injection is much cheaper, easier, and more effective. That's my plan anyways: pull cold outside air in, through the intercooler, then final chill with meth.
