Default Cooling down the engine bay....ahhhh

Well i was doing some thinking, and i thought... how can i keep my engine bay cooler??

1. By letting more cool air in

2. By letting more hot air out



So the first and easiest step seemed pretty obvious. Make the chimney larger.




The next step will be inducting more fresh air into the engine bay somehow... still working on that one. I have some ideas for it.

1. Change my wrc style headlights to be functional air inlets. This one is going to be a bit tricky b/c i'll have to find a way keep my turn signals legal. I was thinking a couple of different setups might just work.


a. Swap positions with high beam/low beam projectors, so that the high beams are on the outside. Wire up the high beam light to flash with the turn signal, since white turn signals are legal in florida, i think i would be ok. Obviously they wouldn't work with the brights on though.

b. Relocate the signal bulb to the bumper wrc style.

c. Relocate the signal bulb to a different position on the light, like on the side of the headlight intake. Leaving the reflective material intact, but covering it with clear coat to protect it from bugs and rock chips.
d. just remove it b/c no one uses turn signals in florida anyways j/k



Here's a pic of the prospected headlights i want to modify





Here's a pic of the functional scoops on the wrc car





input? suggestions? opinions?




OR should i just bail and leave it alone, b/c the difference wont matter and it will just look ugly.

just fyi, pumping more air into the engine bay will produce front end lift at higher speeds

what you really need to do is pull off everything exhaust and heat wrap it. then get a turbo blanket for the turbo. get some gold foil or reflective material and put it around the sides of the intercooler.... those things will drastically cool down the engine bay

/\/\/\/\ thank you

you're here to help aren't you??? those are some really good ideas!

can i wrap a stock header? I dont see why not except that pesky heat shield.

one thing i worry about is wrapping the turbo, i dont think i want to keep heat in... thats' the probl with wrap, and why i wanted to vent.. but with vent you get lift which is also something i want to stay away from...

interesting predicament

you dont heat wrap the turbo you get something called a turbo blanket... and the turbos are designed for vry high temperatures, it is fine to put a blanket on it. thats the best way to reduce engine bay temps

Heat wrap the headers, heatwrap the DP until it's about 1' into the underside of the car (deflects heat while still minimizing backpressure), get a blanket for the turbo, upgrade to silicone hoses, use a higher percentage of water in the coolant ratio (also add Royal Purple "Purple Ice"; better than water-wetter), go for a higher quality oil (insert Royal Purple plug here), increase the size of the hood scoop, wire the water spray to come on under WOT, look into spraying meth, get N20 or C02 for intercooler (note that water and C02 is corrosive), add heat shielding to your CAI (go buy one of those foil windshield heat deflectors, cut it to the right size to wrap your CAI pipe loosely, zip tie), TB coolant redirect, clean your radiator (lol), modify your stock turbo heat shield to fit your DP (then cut strips od DEI exhaust wrap and silicone glue it to the inside of the heat shield; take DEI silicone spray and add several light coats to the inside and outside), lower PSI radiator cap (or, in your case, coolant reservoir cap), move the 2 coolant lines away from your CAI (even if it means extending them or *GASP* using zip ties), remove the bracket from cyl. 3 to up pipe (just look, you'll see it -- unnecessary, direct heat transfer to motor from exhaust).

Can't think of any more right now, but that's a good start that will REALLY add up. I saw a visible differece in the temperature gauge on my car!
