Any Ideas how to reduce Engine bay temp?

M.Etreby · 09-29-2014, 07:07 AM

I was just thinking how to reduce the temp of the engine bay as much as possible, its really affecting the air intake box pretty bad. I feel it a lot when i try to swap the air filters just after coming back home from an hour drive.

Any thoughts?

wrap your headers

Bms cowl delete. I have that on my 330i and it really makes a diffence in cooling for $50.

That cushion under your hood keeps a lot of heat in.

Cooler fluids will help with underhood temps.

Ceramic coat exhaust manifolds.

Gold. A lot of gold.

What do you do with those sensors you remove? Do you just leave them there?

Not at all. It would make them worse. The engine is gonna generate the same amount of heat which will still go to the oil and coolant. But with a bigger radiator and an oil cooler, youre rejecting that heat into the engine bay instead of keeping it in the fluid.

Ceramic coated manifolds will help tho

I don't know anything about ceramic coating the exhaust manifolds, but wrapping them will just cause them to prematurely fail. It keeps too much of the heat within the metal and causes extra stress. At least this has been my observation in track vehicles, maybe not so much on a DD.

Also depending on where you live, titanium wrapping wxhaust causes a lot of rust

it's not the heat. wraps trap dirt, oil and moisture.

ceramic coating definitely helps a bit. you'd be better off getting brand new headers coated though than having yours cleaned and coated.

Zip ties is what I used. On the BMS site, they left a lot of the stuff loose, probably just for the pic. I zip tied all the cables to the 2 strut braces. Basically bundled them and then tied the bundle to the brace. The 2 small sensors on either side of the engine, I zip tied to the closest thing I could find so they're in the same spot.

I have no idea how much heat this is allowing to escape from the engine bay, but it seems like there is some. At lights while idling, all I see are heat waves coming from the back of the hood.

One downside is that you really can't not use the AC unless it's really cold out. The system no longer pulls ambient air, it's pulling hot air from under the hood.

Only sensor is the HOOD close sensor. That is bad for alarm, it will not deptect any hood open Alerts

I dont like the fact that the cables are on the Engine cover too

very mixed reviews on the cowl delete..

get a hood with fins on the top.. I mean it might not be to your taste, but vipers have always had them for that reason, among others

GoRomeo · 10-02-2014, 11:40 AM

Funny u mention, in my hood the freaking pieces of rubber near the lever are all melted due to the heat too? WTF?? they are liquid coming towards the grills. I had to clean it the other day but was a bit mess. Anybody experiencing this?

You are talking something like the M, right?
