any ideas for cooling the engine bay.

[sexspecvr4]

just a quick questions for all you vr4 nurds, any suggustions or iders on how to keep the engine bay cooler or is there any other coolent that keep the car from high temps. i know that our cars have hight under bonnet temps but all that heat carnt be doing much for the the hoes and plastic components(frigial shit)

cheers fellas

Most cars will benefit from some sort of heat vent in the bonnet you hay even try to give ceramic wrapping the exhaust. Even getting a oil cooler on the engine will help ad as the turbo's have an oil feed to them you could put a oil cooler in the wheel arch or even look into were Nissan put their stock inter coolers and try to mimic it with your oil cooler if possible.

yeah thanks mate for ur imput just some people have said to put spacers under the bonnet hinges???

I thought our turbos were just water cooled?

I thought our turbos were just water cooled?

All turbo's will need some sort of oil as the bearings will need lubricating some how.

That's weird as I'm sure I saw someone in the know here say they were just water cooled.

Must. get. glasses. lol

Edit: did a search, someone mentioned that the were also water cooled. My apologies tommo

 

[sexspecvr4]

yeah well realy i just wanna get some of the members imput on how to release some heat or what have other people come up with!! eg.. bigger grill opening rasing bonnet ect..

 

[sexspecvr4]

our turbos do have an oil feed if you take ur intercooler piping off the top of the turbo and run ur finger on th inside of the pipe you will see traces of oil but anyway back on to topic...

 

[Guest]

as tommo said the oil is to lubricate the water lines are for cooling..

vented bonnet and if you have your stock under tray leave it on...

 

[sexspecvr4]

wat differance does the undertray do?

 

[dimi_108]

Removing the under tray cover will expose all of the bottom of the engine. Mine is off for now to monitor my leak.
While it's off, i've noticed after a long, hard drive, if i open the bonnet when stopping, there seems to be less "hot" air trying to escape the engine bay.
When it was on, there seemed to be quite a lot of hot air. Also, on some occassions with it on, if i had my arm resting out the window i could feel the heat escaping the engine bay on the side of the car.
With the under tray being off at the moment, i haven't experienced that much heat from the engine bay.

I still recommend an Evo bonnet though.
That will be early next year.
Our engines get really hot don't they?

 

[Guest]

True the engine bay may be hot but is the engine too hot? Maybe its a sign of the engine getting rid of the heat rather then being too hot. my 2c lol

ur not wrong just wanna make the damm thing breath a bit..

In the custom bonnet thread there's some interesting discussion and links that will give you some good insights into what can be done and how to do it. Getting the balance right to promote negative pressure in beneficial ways is key here - you want good flow through your coolers and suction that pulls hot air out of the engine bay. If you get it wrong you'll just end up with dead air sitting in pockets around your engine or worse: positive pressure BEHIND your coolers

Adam, i strongly suggest NOT to put washers in your bonnet hinge..

few reasons..

1. Dept of Transport can and will defect your car for it..

2. if you get into a crash.. instead of the bonnet crumpling on its own, it'll just snap off from where the bolts are and might cause bodily harm..

how i know this? remember my mishap back in April where the bonnet smacked on my windscreen.. it wasn't the bonnet that smashed the glass, but the bonnet hinge which closed on its own.. kinda like from | | to / \ so i learned through the hard sad way..

3. It may loook good.. but not enough to dissipate the heat from inside the engine bay out to windscreen.. (might need other's opinion on this one)

 

[matchtheclown]

The engine runs fine as it is man. Why are you worried about getting rid of extra heat?

Engines get hot when they are pushed that's normal.... It's a PC CPU which is going to be able to be over clocked if you can get the temps down with a refrigerated heat sink.

 

[SiliconAngel]

On the bonnet raising thing, it won't work anyway as you have too much positive air pressure just in front of the windscreen, so no air will exhaust from there anyway.

Then why am I seeing soooo many commodores out on the road with this mod in place? Its looks like they cant even close the bonnet rite

 

[bradc]

Well it probably does help when stopped, but definitely not when moving at speed.

Steve - who said they are any where near as intelligent as us!

 

[SiliconAngel]

Don't you think their depth of thought is self evident? They drive commodores... 'nuff said really
