Please post suggestions on how to keep the engine bay temperatures cool.

This is what I came up with searching:

1 - Put washers to raise the hood from the back.
2 - Relocate battery to trunk.
3 - Someone relocated their windshield washer tank, but forgot where.

There are other suggestions like hacking up your hood, civic radiator, basically reducing parts that arent needed so there is more space for cooling down. Please post your suggestions for STREET CARS

 

Doesn't raising the hood at the base of the windshield push air INTO the engine bay? That's where the air pressure is really high I thought?

 

Thats what I've read, but you may be right.

 

Raising the hood at the rear helps create a low pressure area and creates a flow from underhood - out the back. It does help. One thing that may look ricey if done wrong, but if done right, wont be noticed much, is placing a few small louvered openings in your hood instead of hacking up the hood.

Also on d series, the mugen thermostat, rad cap & fan switch all fit the d and help cooling temps.

 

How about creating a heatshield for your manifold/turbo like stock turbo cars have, I think thats one of the main reasons cars with a/c overheat due to the tremendous amount of heat. Especially when your turbo is about an inch away from your fans

 

jethot coating and liberally applying heatwrap helps a lot.

Exactly. The only real way to keep the engine bay cool is to keep the heat out of the engine bay.

Wrap the header/manifold, and put reflective heat tape over anything close to it to keep the heat from soaking into those components.

You can also fabricate a heat shield to place behind the radiator so that the air flowing through the radiator is directed down and out of the bay instead of flowing straight into it.

Header wrap will make the largest difference.

 

has anyone ever put the radiator underneith the car in the back?, and run some coolant lines down the sideskirts or even through the car? have it at a slight angle with some sort of duct & fans?

 

I have heard that removing the weather stip under the rear of the hood will let some heat vent out.. Like adding the washers but less ghetto. I did it but have no results to provide. Bottom line is everything down there is hot. Even if you keep air flowing through it things are still very hot. I don't see why you would move the radiator.. That is the coolest part of them all.. The manifold is going to reach 1500+ degrees and put of alot of heat.. The radiator is about 180*

 

where can i get heat wrap from?? anyone know?

&lt; $50 a roll.

 

thanx man i needed that

 

well in my case, i took out the a/c, so i have an extra fan, i hooked it up to a switch, so when im in traffic, or at a light in the heat, i turn on the fan. im not too sure if this would help any, but how about a different front end, like with a wider front opening?
also when im driving in high heat, i try not to boost as much, keeping the load of the engine.

do you have any pics?... i'd like to see this... also, have you driven through rain since doing this?... any side effects?... thanks...

 

i am interested in the fan idea to push out the hot air, anyone have any ideas.

i know this might sound ridiculous, but how about incorporating some type of misting system inside the engine bay? ... just a thought.

 

imo it would be better to have a fan and push cooler air inside instead of trying to pull the hot air out of the engine bay.
as for the misting thing, not too sure, crzy idea what if you could do like an evaporative cooler type thing, where air goes through a pad soaked with water and pushes cold air into the engine bay as your driving.

 

that is actually an amazing idea fmax.

i actually thought of that, it might sound obsurd, but why not use current AC to blow into the engine bay instead of the car (i discussed this with Spade and he said AC will of course put load on the engine).....but since i dont have AC i was wondering are there other ways to do this...

Anyone know where to get or make a heatshield??

 

just grab some sheet metal from home depot and make one

 

instead of putting a load on the engine you could place a pad type of thing where your a/c condensor would be and have it soaked with water through a type of pump, then have a reservoir on the bottom that recirculates the water, so its primary function is just to get cool air into the engine bay.
hmm i dont know just a crazy thought *shrugs*

 

I was thinking about taking some heat insulation padding and clipping it to the underside of the hood. I got the idea from my friend with a GSt, junkyards should have it if youre lucky.

i just did that tonight, and it was easy as ****.

 

I have read a lot of posts that are ANTI Heat wrapping because of the whole trapping hot air on the outside of the manifold cause's it to corrode theory, which is probably quite true. But if you HPC your manifold and then heat wrapped it you wouldn't get that problem right?? Thats what I am going to do if I get a positive responses.

Just a few posible things to do.

 

There are a whole bunch of problems here.

1: The base of the windshield is a high pressure area, due to the curvature of the front of the car. If you raise the rear of the hood, the air will flow INTO the engine bay, NOT out of it. On the other hand, this is still a good thing.

2: Relocating the battery will not have any effect on heat.

3: Relocating the windshield washer tank will have no effect on undehood heat.

4: Using the A/C to blow cold air into the engine bay will increase the overall underhood temperatures. Think about it, all the A/C does is transfer heat energy from one place to another (normally from the cockpit to outside). Where outside does it transfer heat to? Right in front of the radiator. Also, because the A/C is not 100% percent efficient, for every bit of cool air it blows into the engine bay, you would have more heat created right in front of the radiator, right where you do not want it.
