spray on intercooler

[williambavila]

I was listening to some guys talking about using some kind of spray on the intercooler to cool the air.would this benefit a daily drivin car or only a drag car.. I get the idea to cool the air but sounds like more work than it may be worth.

At uti in florida they strayed nitrous on the intercooler of a moderetly modded srt4 neon and gained 40whp. I've thought many times about doing ur to mine for the track

well what about c02??

 

[notacarlo]

C02 - no

Ice forms on the intercooler drops to the tarmac and you get kicked out of the track.

Why not do it from the inside? ALKY.

Never thought about it like that, that's very true

i should have been more specific i do have alky. I was wondering if anyone has a system set up that may have a button you could hit kinda like nos

Just do a pre-intercooler nozzle....you will get the same gain...which is probably nothing. I would think that if you hit the intercooler with alcohol, then also had it spraying the up pipe there would be some measurable gain.

Is this a thread about how to make charge air cooler/colder?

The older STI's had a button that would spray water onto the intercooler, but that is a purpose built rally car. If I saw water dripping onto the launch pad underneath one of those suckers, I would shut my car down and raise hell. Nothing like blowing your tires off because of someone else leaving a wet-spot....hey wait...I think my wife has yelled at me about this more than once.

All kidding aside, if you want to spray your intercooler on the street, do it. More stuff to fart around with while you are trying to play a mind game with the dude next to you at the light. Maybe you're a multi-tasker...I am not, I am Polish.

If it was a truly effective way to improve what we have, I'm sure there would be a lot more than one of us chiming in on your question.

Also, I'm guessing you have a stock location intercooler. If so, get a bigger one and put it up front. Measurable gain for sure.

Not trying to be an a$$, hope this helps.

The spraying helps with heat soak on the core, but at what price is this gain worth? NOS is obviously going to put the deep freeze on the core but again, spraying the inside is WAY more efficient so why do that unless you're going to spray both outside and inside for max performance.

The Evo also had the intercooler sprayer, it does help with heat soak and of course Ralley Racing would make sense here. But if you're on a budget, inside vs outside every time.

Please forgive my ignorance, but how does spraying CO2, in short bursts cause ice build-up? Wouldn't the best way be to hit is a few times with short bursts? Any cooling would be helpful if the IC is heatsoaked, correct?

Cars are simple. To go fast its all heads/cam/boost and getting air in/out of the motor. The issue with a heat soaked IC is that its outlet temps are going to be higher. So what, the methanol will calm it right down. And the air rushing through its fins will also calm it down as you drive the car. Unless your IC is boxed in.

The only way you can make power on air coming into the motor is keeping it at a reasonable temp of under 130 degree's. becuase it comes down to 120 or 100 doesnt mean the motor makes more HP. Maybe 1-2 hp. The problem with high IAT temps is the motor will detonate when those temps climb up. Think of working out in the sun vs an air conditioned room. You'll get a stroke easier when its 150 degree's outside and you exercise.

So how do the spray IC work.. simple you take an application with too small an IC and no other cooling(ie meth) and cool it down.. the computer see's the lower IAT and gives full timing.. whalla you have extra HP.

On a Buick with a meth system.. nada.. zilch.. zero.. you will get from doing this. If anything the car will slow down from the added weight of the equipment added.

CryO2 makes intercooler spray kits that use CO2. NOS, Edelbrock, NX, etc. make spray kits that use NO2.

 

[it's just a six]

I believe there is a company that sells intercoolers w/internal passages that will allow Co2 to flow through the intercooler inside,not just blowing Co2 on the outside.

I'll try to llok them up when I get a chance.

thanks man thats what i wanted to know

Again, if spraying the exterior of the IC was a good idea...for the Buicks...people would be doing it and Razor would be selling the kits to compliment his alky components. Proof is in the pudding.

As far as the C02 goes, if you were staging you would be emptying a bottle on the intercooler and kill it when you launched. C02 is high pressure for it do give the desired cooling effect. From the temperature differences between the C02 and engine compartment it will instantly condensate, then start to freeze. People (Buick in specific) have done this and got booted. This was back in the 90's too.

If you want to go that route (not speaking of the OP as he seems to get the point now) then go to Pep boys and load up on flames, magnetic portholes, and curb feelers to complete the package.

The only way I could see this working would be in the pits to cool the intercooler down quickly. Other than that you risk water under the tires.

 

[Grumpy]

this was a fad back in the early days with Buicks.. Fad didn't last long BUT the "kool guy LOOK" was intimidating .. Didn't do squat but had the look

Julio: How important is the location of the IAT in the overall scheme of things? I use your alky system, FMIC and TT SD chip with the IAT located in the connector hose in the MAF pipe and it seems to be working great. I've read varying opinions on the location of the IAT and I'd like to hear your opinion. I think it doesn't matter as long as you get consistent readings and you adjust fueling according to what your WB, EGT and O2 sensors tell you and how the car runs.

I also considered using CO2 to spray on the IC until I thought about what something so cold would do to the welded joints.

Thanks.

Phil,
IAT is only an issue when the chip makes a tuning decision based on its readings. Aside from that, no issues.

The weight of the CO2 kit is offset by any performance gain.

Have you tried locating it after the intercooler and compared the results?
I have the same setup and its located in the up pipe before the alky.

 

[Quik Six]

I haven't done that and after reading this thread, I'm not sure it is necessary.

I do use the SD chip and I'll check again with Eric and Steve because I think the chip does use IAT for computing fueling. My thought is that if the difference between the reading in the MAF and the up pipe is reasonably consistent, adjusting the fuel from either source would also be pretty constant.

If you hot lap your car or if you made to the finals on Pinks, heat soak on the IC would probably kill you if the IAT was in the MAF.
