any tips on keeping the engine bay cooler with a turbo setup?

 

Cut holes in hood

Why do you think Evos have the vents?

 

+1 but i wouldnt recommend cutting holes lol just get an aftermarket hood with the mesh on top looks sick and very effective

 

divert your A/C hosing to your engine bay (^^,)

 

You could do like honda guys do and what i did space the back of the hood up just a little and get longer hood bolts. I dont know how much it helped but it doesnt look bad and it has to help some. :P

 

ill be getting an r1 cf hood.. plenty of vents.. i havent been having any cooling issues unless its 95+ and im stuck in dead stop traffic.

 

Screw all that.

Keep the heat where it belongs.

Ceramic coat EVERYTHING that gets hot. Watch and FEEL a difference.

I have, manifold, turbo, o2, down pipe all coated. The only radiant heat you can feel is from the motor.

When I build the head/block. I am going to talk to the shop and see if I cant get them coated as well... I would be curious how a ceramic coated block would affect bay temps.

 

how much did it cost to have the turbo stuff coated?

 

i agree ceramic is the way to go

 

Depends who you use. I use Tirado Custom Coatings.

Manifold- $85
o2 housing- $65
hot side of turbo- $60
downpipe - $20 per foot

 

They don't do it for cooling purposes . The guys i know do it because the valve cover hits the hood , taller motors like H22 hit the hood .

 

Ok so call me green lol what exactly will this accomplish? Longevity of parts? More heat inside so better atomization of fuel? less heat outside? just theories lemme know...

 

I never thought about just coating everything. I'm been running only one slim fan on my turbo setup for almost a year now with a VIS vented cf hood. I havent had any over heating issues or anything. The only thing that happens is on really hot days (95+) I lose some boost pressure(2-3psi).

 

I guess you could also use some water wetter and a better radiator to try to lower engine temps.

 

Not really - the point is more to keep HEAT in the parts that are designed for it.

Sure your engine bay harness and sensors are not going to die at 200 degs or even 250. But over the course of 5 years - that will break down stuff a lot faster then say if you had stuff coated and now your engine bay had next to no radiant heat, and the bay temp was only 140, instead of 200, or on REALLY hot days it only got to 180.


More heat is kept within parts and dissipated by the coolant system and vacated out the back of the car by the exhaust.





Not to mention - they - SAY - That keeping your hot parts, exh, turbo, o2, etc all coated maintains higher velocities of air. Spooling your turbo faster, and less heat in the intake from radiant heat means cooler IAT's.
