On Saturday, I'm installing brake cooling ducts on my car. I had the idea that possibly - what if you routed the ducts to point at the turbo? At speed, this would greatly help keep the underhood temps down because it would take the outside air coming into the faux bumper vents, and route it straight at the turbo.

Has anyone done/thought about this? I might end up splitting the duct on the passenger side so that it'll cool both the brakes AND the turbo. I know that the cooling efficiency on the passenger side will only be half as much that way, but anything to help keep the turbo/underhood temps down.

I know a lot of people are having heat issues and this might be a great solution to that problem, especially if you vent your hood.

 

The amount of air that flows in from the front is a tad bit higher than what a 2" duct can provide

Air is also drawn in from under the car in certain areas if I remember some tunnel tests correctly on average cars.

 

So you think that even if the duct was pretty close and pointed directly in the vicinity of the turbo it would just be a moot point?

 

At the very rear of the firewall there's a downward flow of air and at the front there's an upward flow from the bottom of the car. That's probably why there's a plastic shield right there on the car. I just don't think it will be significant enough to actually cool the engine bay and just look weird. It could be a good source of cold air for the turbo though. The best thing to do IMO is get a vented hood with vents towards the windshield or make some vents on the factory hood. I saw some pics of some guys who cut theirs out and put some mesh and it looked pretty clean in the pics.

Then again maybe it looks like crap in person.

 

^Yeah there's a few of us Atlantans that are doing DIY hood venting. I'll be sure to post pictures for everyone when that's done

Thanks for the help

 

From a roll s2k has no issue with cooling, on idle in traffic you need vented hood. On the track vented is nice also.

 

Ken, your up early!

 

yea I am thinking about cooling mods for my car , time to call evolution.

 

Good luck bro. Call me today

 

These pictures are taken through the vent on the turbo side of my Top Secret Hood. The hot side is right underneath one of the vents and I know this has to have some major cooling contributions. Definitely get a hood.
