custom engine cover an battery cover

hi guys, im getting a custom cover made for my td4 engine an battery an was wondering before i do it if the will be any problems doing this in either aluminium or stainless steel?

obviously this will make my car alot faster lol

its not expensive an thought it would look pretty nice with all my uprated bits under the bonnet, shes really starting to take shape my girl..

I always thought the plastic acoustic covers were there to reduce noise.

+1

That's exactly what i was wondering...

lets see some pictures then

Just trying to find out first if it will cause any issues before getting it made, pretty decent looking though an will look decent once ive done the rest of the air intake pipes in aluminium like winu, got my nice clutch going on tomorrow along with my performance poly bush suspension kit,.

Then the end of the month she will be going of to cybox for a high flow sports exhaust, then to allisport for intercooler an pipes... �� Then the real good stuff comes like the uprated turbo an injectors then finally my remapping ��

That's this year covered lol next year ill concentrate on looks but this year its all about making her the fastest Freelander on the road....

I would guess a metal cover would change the heat characteristics. May spread heat to where it doesn't normally go. A metal battery cover is something I wouldn't want in case it shorts the battery. Personally I wouldn't buy either. But that just my thinking.

I'd be double, and triple checking the fitment of the battery cover before going anywhere near it. If you do go for it, make sure it's lined with at least duct tape internally above the battery, so if anything does go wrong your hippo doesn't end up a smoking heap.

Too late

Battery cover can be done from metal with no problems. First of all, "+" terminal is covered by rubber protector. Second, underside of battery covers got some protection material on it ( butyl foam). So it's safe

If you want some better look of your engine, just use "small" cover from earlier models (cover only injectors)

Winu absolutely love your Freelander an what you have done to her, you've gave me lots of inspiration. But im sorry mate ill let you have that title for now but i got afew tricks up my sleeve yet to make her the fastest girl round �� lol

May not bother with the battery cover then an just do the engine cover, may even just chrome the plastic now as its another option as dont want more noise or vibration coming from the engine bay an diffo no heat problems lol

Challenge accepted - don't forget to publish dyno graph

It will be my pleasure mate

I would like to see the winner of you two against Disco Mikey's 200bhp 1.8 turbo before he needs another head gasket/gearbox/IRD/rear diff

Shoud i show V6 turbo ?

Lol yes please

Just speaking to a company who do that spray on chrome an they said i could use that but maximum temp is 100c, my question is would that be ok to use then on my engine cover an other little bits under the bonnet? how hot does it get under there on a hot day stuck in traffic? or am i better off just going for the custom covers made out of ss or aluminum? Decisions decisions...

adding weight .. and heat retention to the engine bay don't seem to make too much sense .. i.e if more power is the desired outcome ..

battery aside .. at least make sure the air intake duct ( pre maf ) doesn't get any hotter than it normally would ..

hippo has a point :

and keep any extra heat retention away from electronic devices ..
i.e. injectors .. sensors .. wiring .. ecu .. fuse box .. etc etc
as the life of electronic components is directly related to the operating environment temperature

FAQ: At what temperature do conventional electronics packages fail?

Theory is nice... but practice is better

SS intake is not heavier than stock plastic stuff, but have a lot less air restrictions ( we use 3 inch straight pipe instead of plastic flat channels). Temperatures also are about 5 deg lower from stock.

Winu, your the man...

So what are you thinking mate, do you think i shouldn't bother with the battery cover an maybe just go with the spray on chrome for the engine cover an just do the pipes like yours but in polished aluminium?

What do you guys think the average temp under the bonnet is when your stuck in traffic on a hot day? Its ok upto 100c the fella reckons on the phone
