Co2 Spray For Intercooler

[seventytwo]

Tricked Out not a bad show, very much for the rice brigade.

Anything that reduces intake temps has to be good, as they said on the show the hotter the day the more noticable the effect.

I would think that putting CO2 on your intercooler could also cause your car to suck the CO2 into the motor and would reduce the performance.

I would also think liquid nitrogen would be more effective and much cooler.

I'm guessing you don't realise how an intercooler works then.. as the CO2 would not enter the engine unless the spray goes up into your airbox/filter.

Otherwise wouldnt see people spraying their intercoolers with fire extinguishers or water bottles at Dyno comps.

I do know how they work and I was imagining that it did go through the inlet indirectly. It is a possibility that it could happen if you are spraying enough to cool the intercooler externally.

I am definitely considering one of these next. The XR6T engines run so hot even the bigger intercoolers get heat soak in a relatively short period of time!

what about dry ice in a small mesh container mounted in front and in contact-welded to the intercooler.

the lid could be on top and locked or cabletied shut.

my mate did this on his RX7 about 8 years ago and worked well for drags.....another put dry ice on his top mount before drags!!!! This was before I knew what a car was unfortunately so dont have any details.

They company selling this gear state that care must be taken to ensure the the CO2 doesnt enter the engine as it can cause a decrease in engine performance....i think it would work well as long as you ensure the eng didnt suck it in.....would be like drving around in winter everyday......

And the 2nd CAI's we all have pick up just to the left of where this is...

Very real possibility of this happening unless your moving pretty quick...

Chris, you seem alot smarter than you portray on Nicks site!!

Not sure how effective this would be overall. Yes, it would significantly aid cooling of the IC however, this would only be for a short period on a strip as the consumption of CO2 to achieve good cooling would be significant. The downside is the extra weight you are carrying in lugging the CO2 cylinder around in the boot.

For my money, I would be investing firstly in a bigger IC as it is there 100% of the time.

Thanks guys for all the extra info!!!

In the show they had the kit wired up like this.

An arming switch to turn the whole system on/off.

1 push button switch on the dash to use it at idle or whenever.

1 switch down at the accelerator to work only when fully pressed, ie at WOT.

So the idea was at the drags, to give it a 10 second or so squirt at idle with the dash button just before launching, then it continues basically with the use of the accelerator @ WOT as you go hell for leather down the quarter.

They reckon you can get 20 uses like this.
