Liquid charge cooling vs Air Intercooler

fil_auto · January 23, 2013, 05:11:20 PM

I reckon and nice vmount CC would do the trick nicely! Sorry :p

I have a front mount - big ole Apexi GT IC, tis good.... but I\'d like a V mount next :yes

Yeh I agree with marf, bring it on big boys, now there\'s 2 of us:)

This may seem out of place but it is linked to the thread but why did we to from air cooler to water cooled engines?? Because water cools betterer:D simples.

Quote from: Grizzly;848565Every one seems hung up on air inlet temps, you are not going to see much gain between 18 deg and 10deg? the WI makes a huge difference and not to the Air temp but to the EGT (much more important) the air temp makes FA difference to this.

At the end of the day air-air is fool proof and low maintenance plus makes a perfect road/track set up

water-air is much more complex and you run the risk of leaks etc then you are effectively running with no ic plus adding weight.

I see why you might run one for a Drag car, as you say you could mess about with it and put Ice in etc but you can simply spray a CO2 fire extinguisher at the air-air ic and turn it to a block of ice if you wanted to on a drag run so no gain there.

I can see the IC pipe length coming up in a minute but modern Turbo\'s spool and the Air speed in the Inlet run will help make little to no difference in Response and why would you need fast response on a Drag car

IMHO

Does the AIT change fuel amounts injected into the engine? Set by the ecu? Same as with water temps? Low temps allows a bit more boost once warmed up?

I read it on Internet;)

If you\'re building a drag racer then water to air makes sense. But for most other applications air to air with WI is a better option.

Coming from a man with no turbo! How dare you comment?

hehehe

Just a little n/a two rotor.

I\'ve got a turbo on the daily.

just fduk off any type of cooler and WI and just run meth lol :p

Then you\'ll need a mad fuel system and huge injectors and you won\'t be allowed on the road. But it\'s cool, and you\'ll probably not get any carboning up in the motor.

Can you tell me how much more Hp you will make having 10deg inlet temp as opposed to 18 degrees?

The boost thing is down to WI

egt\'s directly effect how much boost you can run, i personally found i made more hp fitting a well flowing IC as opposed to loosing a few degree\'s air temp But i made Massive amounts more power when fitted wi and got my EGT\'s in check (you need to have an EGT gauge to see how well your car\'s set up or not and how much more you can safely push it)

Shall i check back when you have actually run a CC

For an 8C air temperature differential you will make 80Hp

lol. Until you can prove me wrong with evidence then I stand by my outrageous comment.

Air temp will make a difference, if it didn\'t then why do we run coolers? I would love to see how much a cooler actually cools the air after the turbo to after the cooler, I bet its quite a lot.

I know about the EGTs, tuning these along with AFRs and the whole shabbang makes you able to run your engine harder, BUT if you don\'t control your air temps then your EGTs aren\'t going to be right are they? The WI helps make the air more dense and also draws heat out of the air, denser air and cooler air means more oxygen.

No point preaching to the church goers is there. Oxygen fuel and heat are the Ingrediants for burning/combustion this is why in nitromethane engines are burning 4 pounds of fuel for one pound of air, the nitro is fuel but it also has and oxygen molecule In there, blah blah etc etc

Basically what I\'m saying is the lower the air temp the more oxygen, more oxygen (boost) plus more fuel = broken gearbox! Lol

Anyway where was I?? I can\'t wait to run my cc, it should have prety damn good flow and huge cooling ability.

All ready said this, most definately agree :evillaugh:eek::Laugh

Since the power of the engine is related to the heat produced and you want to keep your EGTs at a specific level it makes sense that you want the coolest air possible going in to the engine. Not least because cooling makes the air denser so you can add more fuel and get more power.

Air temp will make a difference.

I\'m not saying air temp doesn\'t make a difference, i bet the difference between 10 deg and 80deg inlet temp is massive but what i\'m saying is the single figure Difference in air temp will not make that much difference to you peak hp figure.

Air temp really doesn\'t effect your EGT. AFR or Timing or WI does.

Nearly, Yes your EGR is very Important, there are ways to lower your egt but at a set hp you will find the Inlet temp will not make anywhere near as much difference as say WI (and i don\'t mean WI lowering the Inlet temp, the water directly lowers the EGT quite a bit by effecting the combustion). Don\'t forget i\'m not talking 20 or 30 degree\'s here in the EGT 1000 deg 5 deg inlet temp don\'t make allot of Difference.

Grant Monkhouse · January 23, 2013, 08:52:53 PM

Yeh water slows down down the flame front and makes it burn cooler etc. it would be nice to have air temps lower than the outside air temp, that way you know your choice of cooler is working right.

One thing I actually would like to do is move my engine radiator out of the engine bay, mount it in the boot, see how much extra heat you would lose by getting rid of that PITA heat soaker.
