Lancer Evo VIII hood vent

[NeilBlanchard]

Hi,

I see that the (newest?) Mitsubishi Lancer Evo VIII has what appears to be a radiator heat vent in the top of the hood:


While it is not ducted, do you think this either helps the cooling and/or helps the aerodynamics?

That is the previous generation Evo. I think it is to promote better flow through the rad & intercooler (you can see the intercooler in the lower grille) by letting the hot air out. Here is the latest generation http://pictures.topspeed.com/IMG/cro...a-6_460x0w.jpg

Looks like cooling vents but for the intercooler not the radiator.

That's pretty far from the newest EVO. They vent the hot coming off all of the various radiating thingies in the front of the car: radiator, AC condenser, (huge) intercooler. Dunno what it does for aero dynamics but it can't help but be good for the airflow across all of those gizmos.

i believe this is the current one

Where does the Turbo sit on that car? Is it inbetween the heat exchangers and engine block? Could be another huge source of heat right there.

ah ha. see theres the heat..

Hi,

It's on the cover of the current Car & Driver, so it can't be that old?

The Evo VIII was in production from 2003 through 2005.

Do turbochargers generate much heat in themselves? I guess the exhaust gas turning the turbine slows down and sinks more heat into the manifold/turbine assembly, but wouldn't the compressor side of the turbo be reasonably cool?
