Looking for a serious solution to cooling your intercooler? Check this out fellows!

The optional "street version", it has an adjustable pressure sensor based on boost to spray water. Interesting, huh?


Intercooler Spray Kit

Here's another one, I saw it installed on a turbo Cooper but it could be used on the S as well. The controller is adjustable when driving.

Flipping through Sport Compact Car magazine, I came across this:

NX N-ter Cooler Chiller

Universal? +50HP?

What do you guys think?

[FLiPSiDE]

the nos/co2 chiller idea is sumthin i been thinkin about for a while.. excellent for the traffic lite grand prix series
but dont know about the 50HP claims tho

The temp here is -20C and I don't see any 50 hp boost due to the cooler denser air.

It might help in the midst of a 100C day but my guess is that it would just get to back to 'normal' given the smarts in the engine management system

haha yeah well never gets that cold here in sydney .. and in summer during the day u can really feel the drop in power.. and we've had temps of 45 celcius here of late.. no idea what that is in farenheight (or hovever u spell it ) but its way over 100 (which is 38 or so)

Actually we make a diverter for the "S" intercooler that has a built in water sprayer. See what you think.

Hi Jeff,

Where is the water sprayer getting it's water from? Also, what's the level of installation difficulty for this mod?

[SteveS]

I'm in SoCal and the usual hi temp means significant power losses. I really notice it in my 88M3 and it would be more severe in a supercharged setting. I think when my S arrives this mo. the diverter and water spray will be the second mod - after intake. It looks like a terriffic mod for freeing horsepower and keeping engine cool.

Jeff,
Your splitter is pretty trick. Is there some sort of water pump system included or does "sprayer" just mean the nozzle?

Dave,
the splitter comes with the nozzle we make, and hose. As for a pump, we have a pump availible, but when we finish our seperate tank and electronic controll, then we will include the pump.
Right now, the system uses the rear washer pump/reservoir and the factory switch.

Interesting. So you just hit the rear washer and it sprays the intercooler? with windshield washer fluid? Does it still wash the rear window or is it one or the other?

[lotoole3]

Jeff -

Any timeframe on the availability of a diverter kit with pump/tank/controls?

[MiniG]

Maybe Nitrous makes a good window cleaner??

[alta2]

Dave,
yes, when you hit the rear washer it sprays the intercooler with what ever you have in your washer tank.
So you have the chioce, we will be including a tee with the kit so when you activate the pump, it will still wash the rear window.

We should be shipping them next week with the kit standard kit, but as for the electronics and pump, that might be a couple of months or so.

Alta,

Please address this question.

The ECU is very darn smart. This system unless you have constant change will not adjust to conditions such as water spray.

I know for a fact that if you even put a bottle of octane once and a while you will not really notice the difference. You have to feed it to the car all the time to see the improvments.

I got my ECU flashed last week and the car drove like a pig for about 30 minutes until it knew what I was doing. I drove the car like I stole it then shut it down, and **** about 30hp appeared from no where.

I wish this was as simple as a WRX or Mitsu but its not.

[FLiPSiDE]

i dont know about all that, im not all up on the technicalities but the highest dyno score on a stock S was one that had the cooler iced before the run, and when u take ya car out on a cold nite it doesnt take 30 minutes to pick up the difference between hot day and cold nite its instant.. so to my mind cooler air would make an immediate difference, what im not sure of is how effective this system would be.. but im sure it could make some measurable difference, albeit small

Why would the ECU need to adjust to water being sprayed on the OUTSIDE of the Intercooler?

[911ETR]

I guess it was late and I really did not make that clear. All I am saying is that the only hp you will gain out of this is if you are heat soaked and you lost power. You will never gain positive power over what it was when it was cold. Now if this were water injection it may be a different story.

This is just a theroy, this Seimens system is really sort of a pain. I have ordered one of these systems from Alta to test it along with the 3 temp sensors.

There is an interesting thread around the same idea going on over at MINI Cooper Online. Someone had a Nitrous system that they've setup to spray the intercooler with CO2 so it really super chills the intercooler waaaaay down. He can't do "hot day" tests because it's winter. The thread also discusses the posibility of CO2 getting into the air intake as a possible negative side effect. Interesting reading.
