P38A EAS Heat Extraction - Vents?

Henry_b · Nov 11, 2020

Hmm

Been pondering this for a while, I did an EAS overhaul on a RRC LSE a good few weeks ago and those have the EAS compressor and valveblock mounted on the chassis with a whacking great vent in the side, and under operation they tend to stay quite cool..

For obvious reasons..

The P38 having it in the engine bay with absolutely 0 airflow seems to be a bit of a hinderance, especially considering the heat that lingers under the bonnet even under normal operation.

The Box has from what I can see 2 small vents, however they seem to do sweet phuque all in terms of heat dissipation.

Being that heat rises and all that Jazz would It be worth making some nice vents in the EAS box lid, maybe in the side, to allow excess heat to escape under operation...

EAS components from what I understand get quite toasty under normal conditions anyway, even when everything is in 100% tip top shape, but surely every little helps? eh?

Whats the collectives opinion on this....

Ahem...

Cheers Lads/Ladies

Hot air rises, heat is a scalar quantity (has no direction)

I agree it’s a heat trap there. Could run an air feed pipe from below. I removed my EAS box so there’s less heat trapped in with my FIP.
Or feed it from the scuttle area?

Keep it clean, scuttle area indeed,it's only just gone 0830.

I seam to remember mention of another member on here a lady that put vents in her box and painted it a bright colour.

And she also did her EAS as well.

Some strategically drilled holes in the box and lid may help air circulation.

Been discussed before, my favorite if i was to do it would be vent holes in box and a pipe from box to inlet air box so that induction airflow sucked the hot air from the EAS box.

tomcat59alan · Nov 11, 2020

True,I didn't say which way the air would circulate.

I drilled holes in my EAS lid years ago. I had problems with it faulting whilst towing from the Lake District-used my EAS light to reset it. Read the codes on my pc when home when it happened again-can't remember exactly as 8 years ago-but something to do with valveblock/drivers. Thought about it overheating as nowhere for hot air to escape. Drilled large holes and no further problems apart from a dodgy rear height sensor every few months.

Hi great post, it just confirms the belief that those bods at Land Rover Design missed a few classes at college..!! The ones about convection etc.

I fitted an air fitting into my pump and ran an air line into and behind the glove box with the original filter fitted. It now draws cooler air that's a lot less humid in winter and far less dusty.
