are water-to-air intercoolers more eficient?

and what are the upsides and downsides of these intercoolers?

and are they good for street driving?



thanx

 

it's only work well if the inlet water are cold ..i think..

<~~~ don't know much hehe

 

1) Yes, substantially.

-- Upsides of air-to-water IC's are the larger Delta-T's as well as intercooling medium (much denser using water as it as a specific heat index of 4.1:1 compared to air mass per mass)

-- Downsides of air-to-water IC's are their complexity and slight need for micro-management during usage at the track (dumping out old water, adding in a new bag of ice in the tank, recirculating through to cool the core off, etc.)

I use one for street driving and it's terrific -> just make sure the system has large enough lines, a good enough flowing water pump (high volume, low pressure), and a good enough radiator in the front. It *will* work as well as an air to air unit.

what would one do in a cold winter?

 

They work even better in the winter time.

wouldnt it freeze?

 

Not if you put anti-freeze in the water. If you are running an "ice chest" system with dry ice, you would need anti-freeze anyway, as temperatures can get down below -60F. Discounting the freezing issue, you would still probably want some type of corrosion inhibitor, and anti-freeze has this property also.

 

Sweet, that's what I was looking for.

 

Damn son, where have you been hiding?

 

BNR is working on a liquid-to-air intercooler system for the third gen. Should work well.
