Relieving Engine Bay temps - ventilation

Bite the bullet and get some ceramic coating,
Its not that expensive really, mine is getting, done at the moment
I'll get change from a grand coating the pistons, combustion face (including the base of the valves) the pre combustion chambers inside and out, inside the exhaust runners, the exhaust manifold inside and out, the turbine housing inside and out and the dump pipe inside and out.

Thats a lot of ceramic for less than a grand.

Speaking of under the hood tempereatures... I never understood or liked top mount intercoolers and bonnet scoops.
Common law of physics, heat rises and attempts to escape upwards. So here we have air being pushed, through the front of the engine bay, through the radiator, cooling it down, over the fan onto the engine and then the hot air tries to go up, through the IC and bonnet scoop ?? But then you have the cold counter-air being pushed downwards through the bonnet and IC, and you have a result of 2 clashing air fronts.

Ultimate is front mounted cooler, with exit points as far back on top of the bonnet as possible.

Bring your ft mount inter cooler muddy Victoria and you will change your mind, they get hot enough after a mud run with a top mount intercooler without putting something else in ft of the radiator

Dude you're never going to see that $100 dollars. Haha he'll always add more conditions
Especially if he hears that you want to upgrade your radiator! Hahahaha

... are you the same AB that is asking if a bigger water pump is worth trying in order to address your overheating issues?

The overheating issues are totally not related to my intercooler old mate ;)

Yep, I'm a stubborn young buck but i will prevail...

Just towing heavy loads and fully loaded in hot and humid weather caused slight increase in temp, nothing new with these old beasts mate...non towing is a dream, easy money ;)

Had it caked in mud before, all good :)

Ziiiiiiiiinnnnnnnnnnnnnnnnnnnnnnnggggggggggggggggg ggggggggggggggggggggggggggggg, Fish on, Fish on...

ROFL, Hiya mate,

Why dont'cha try one of them, there, new fangled 'lektric pumps like in the other thread or even better nip down to Onga and grab a 4 HP Fire Fighting jobbie?

Sorry, for the hijack, I just got back from a few days field work and I think the heatwave temps over here have fried my brain, I'll stop now... maybe...

what is the main concern getting cool air in or letting hot air out.
We should all put an oven thermometer under
the bonnet and see what the results are.
Sounds like a fair test, If everyone takes the temp near the start battery
we should get some decent data that way.

@ hodge I'll point my thermo gun in my scoop at the intercooler
as soon as I turn it off and see what temps are

Whats a crittical temp for the AUX battery

Found this but might be only good for the 3ltr boys

what size turbo do the 3ltrs have STD?
