Do it as its so cheap according to you and prove me wrong then. How will your cryogenics system improve the flow rate of the intercooler to get more air into it?

Well as cold air is denser, meaning that it's more compressed so to speak, that normal airflow will not increase but more of it will be passing through due to colder temperatures.

And why do you keep talking about a longer travel distance? It travels exatly the same distance. If anything was going to be effected by it going further then turbo lag maybe increased but not throttle response.

A large intercooler would require more time to pass through, I would class any lag after accelleration as a lag in throttle response, to be fair you're right I meant turbo lag.

To be fair you dont know what you are going on about and it shows.

That you in many of your previous posts admit you know nothing about turbo engines and now you seem to know everything in the form of cryogenics for them.

I'm big enough to admit I don't know much of turbo engines, but I fail to see (maybe you could enlighten me) how this makes my knowledge of cryogenics invalid?

Perhaps now you've derailed another of my threads you could explain this to me.

If you are talking about cooling the pipes (which is what I gather this is about...) the standard plastic pipes will split. They are not designed for the aggressive temperature thats needed to make any benefit. You will need to replace all pipes with temperature resistant ones.

Because you can cool the air all you want and make it as dense as you want but if you have a much lower flow rate to an after market intercooler you arent gonna get anywhere near the amount of gains you may get by using the system on a after market intercooler that can get alot more air into the engine.

Nah you spray the front of the intercooler to cool down the air going into it.

Well I said I'm here to learn, why don't you teach me?

Are you capable of adding anything intelligent to the subject at all as so far you've proclaimed that the science behind it doesn't work, that science is magic and that an IC can achieve colder temperatures then ice..

No i havent said that. I have said that it is pointless on a GP when you can just put an intercooler on it which will reduce intake temps massively. If then you still feel the need to experiment with cryogenics then go for it.

So stop trying to be a cocky **** and read what i actually said. As throughout the thread i have said its pointless when you have an FMIC available with proven reductions.

oh ive seen a car on tv that had a switch in the cabin that cooled something, it was the impreza i think

Ah I see. Some higher tuned Impreza's had this as an option at one point.

lol yeah i just found a link on it aswell

It does work but on a punto it is overkill when you have no other mods.

it depends. Does anyone know what a typical inlet temperature is on a J-jet or M-jet?

mk1 GTs had an inlet temp of around 60 degrees as standard. This is terrible, and a CO2/water spraybar on a standard IC would have greatly helped power.

On the other hand, a decent aftermarket IC reduces these temps on a tuned GT down to 25-30 degrees, which has exactly the same effect as the spraybar. Its cheaper, less to go wrong, and doesnt need refilling.

If a standard GP has high intake temps, then there is no denying that this CO2 system would help power... but it is totally pointless when there are better options that acheive the same goal.

NO2 would be a far better bet because as well as chilling the intake charge, it adds more oxygen into the mix anyways. A WON second hand setup will only cost you £300 all told, and provided insurance is not an issue (LOL) there isnt a better £ per bhp mod you can do.

All the talk about a bigger IC causing more lag is nonsense. Simply due to the massive airflow a turbo gives, a larger IC will have a MINISCULE difference in the time taken to get to pressure. Dont beleive me? Well have you been there and done that? Because i have.

The End.

At NIN in January after driving a good 50 miles each Adam's GP Intake was 14 degrees (GSR) and mine 25 (STD).

Just buy a faster car

Your GP will never be a speed demon

I would have to agree with the larger intercooler method, it's tried, it's tested and works ! why bother with dicking about with any other way of cooling the air ?

So erm i was right?! :slayer:

Yes and no but you're definitely a jerk.

It was the STI Impreza WRXs that came out with an intercooler misting system i think.

Yes, there is no doubt that a bigger intercooler is the way to go and will give you the largest single gain. So on that point you are right, I spose.

But if you spray mist on your IC the water evaporates and removes heat from the IC. This is good, always, without doubt, regardless of how big the IC is, regardless of the atmospheric conditions, full stop. It's a COOLER, right? Turbodiesels are more demanding on ICs than turbo petrol motors because they are on boost more.

If you are after more performance this misting will give some. Personally, I couldn't be arsed. I would do what you did and just get a bigger IC. But if you are after those last few %'s of performance then you should do it because it DOES WORK. This assumes you are after performance and drive your car hard of course and I don't know that you are/do.

Awwwwwwww im a jerk.

Read through what i said. I never said it didnt work, i said it was pointless on a standard intercooler when you can just upgrade to a more efficient one to start with. How that makes me a jerk i do not know.
