Cryo cooling

[masterbateson]

This water meth jobby, I take it that the water being injected/misted into a combustion chamber wouldnt cause premature aging or rusting of any cylinder components?

Or is it safe to assume that its in such small quantities that it just vaporizes and puffs off out the exhaust?

Also can you buy a kit for this or is it a blue peter jobby?

Your effectively steam cleaning the engine internals everytime you use it, there wouldn't be any rust as the water is turned to gas and chucked out the exhaust, it's actually meant to keep the engine in great condition according to what I've read

I've often thought that steam in the engine is occupying the space needed for air. I think a decent intercooler/chargecooler has more benefit.

I don't have the air con in my car anymore so I can't even look but could you modify the aircon to run coolant pipes past the i/c. Or would the heat exchange from the air con generate too much heat. This is probably pie in the sky so don't lay in to hard.

[masterbateson]

glad you mentioned this,as i was pondering refrigerant or as you say air con coolant stuff.
Suppose there is no reason why you couldnt relocate the aircon unit into the engine bay, or into the boot even.

no point in trying to use A/C to cool inlet charge. as it's impossible for the system to be more than 100% efficient, you'll always use more energy trying to cool the air(running the A/C) than you will gain back from the cooler charge.

Exactly .. Braking one of newtons three laws or braking thermodynamics or both , cant remember.


Cant get more energy out (cooling) than put in

Good point I wasn't thinking along those lines, I was thinking aircon normally costs you one or 2 hp but you might gain more not from the efficiency of the cooler but lower temps would allow higher boost, fuel etc but if it was that simple someone would have already done it. Although I agree with what your saying I don't think newtons law of energy cannot be created or destroyed is the right law for this its just an efficiency thing. Cooling fans use energy but don't overload the engine enough so any gains are worth it. I've not really put what I'm saying across very well but I hope you get the idea. Got to go out. Not looking for a newtons law argument either before someone tells me I'm wrong.

[2mad]

I dont want to get nerdy ... BUT .. you would need so much energy to cool charge it would way out way hp gained from cooling .

Sorry i cant remember what law its braking .. im not that nerdy lol


Think about the amount of air passes through a fmic and trying to recreate that from an a/c device .. it would need so much energy .


I was thinking of the law , you cant get more energy out than you put in

[Poker Face]

The more I think about it , the whole cryo idea is not worth it unless you are doing short runs drag racing or hill sprints maybe. I don't think a bottle is going to last long so in effect water/meth would probably be better at giving you more power ( I'm not going to start another cooling debate on wi).
As for the aircon idea it was just a crazy idea I put out there, just on the off chance some forward thinking maverick had tried it and succeeded. I may have another crazy idea but I need to check some things out at work before I say it out loud and tbh I'm not holding my breath as I'm probably way off (again).

[2mad]

No mater how crazy an idea its always worth putting it out there .. at some point someone posted im going to spray noz on to an intercooler

I hope this link works? It just downloads as a pdf on my phone.

This was a diesel engine in India (I think ).

Ever used a fire extinguisher on the intercooler before a drag? I was told someone done this at santa pod in an mr2 and they said it went like a fecking rocket

That is interesting .. just remember you would drop power driving the a/c pump .. plus you'd need a heat exchanger rad and fan ..

Going to look into it more it would be nice to have seen the test on a petrol car ... temps were still way high on a diesel , 63c

I thought the same as you at first but look again that's the temperature drop across the intercooler.

[2mad]

yeah its 62c .. 119 in, 62 out, temp drop 57c .. love to see this done on a petrol turbo

[Poker Face]

Lol, I'm an idiot you're dead right. I'd like to see it done on a petrol turbo too.

This has got me thinking..... The Scooby uses an IC spray to help keep things cool.....any benefit with us? Easy to do.

Better off spraying water/meth in to your charge and intake

Na its my fault buddy .. I miss read or miss typed

Definitely- provided your ic has sufficient airflow across it to evaporate the water
