Vented Bonnets + Rain = ?

[Fujiwara]

I'm thinking of getting a vented bonnet but i was wondering.

What happens when it rains?

Isn't it bad to get water in the engine bay?

[Chi100188]

im pretty sure some manufacturers design the bonnet so when there is rain there is a little cover they provide...and you can cover up the vented spots so water doesn't it in or the vent my be designed so when there is rain the rain will be directed to the radiator? or something? hope that helps

Cheers

Mate, let's face it... you want a vented bonnet for the 'agressive look' - as engine bay was, you got all the air you need.

I've done some research into this and unless the vens are face diagnally as in - it's leaning towards the front and it has some sort of cover on the top for running falling directly down, run + engine bay is no good. Especially, think about it, what if it's raining heavily? Then you're buggered.

Think twice if you want one and make sure you choose the right one.

Good luck.

ill still go the Z tune bonnet for the R33 i wreckon its the bomb hahah ill get covers for it

[Yawn]

Yeah mine has a little carbon strip that bolts on to the vent for when you dont need the extra cooling. All for the little extra cost of 2000 yen!

Some come with a rain tray for underneath.

ha ha yeah....think before you buy......it's all fun and games until one day you realised your engine has been soaking up the moisture for the better part of the week.

Your coil packs may get wet...

[mesmerized]

you can foul your plugs

[POLICE]

wouldn't it improve your car's performance even more?

since the water leaking in is cooling the engine bay

[Spunky Munky]

Yeah for sure.... it would be greet for your car.... you get the added smoke effect too... lol

iv drived through hail in mine and never had a problem, they engine isnt cold when its running,

so basically asoon as the water hits it evaporates

[Chi100188]

hmmmm what ali turko said i guess but excess rain hitting engine without the coilpacks cover sealed properly would give you probs ! hahah

[funkymonkey]

just make sure you get one with a drop vent towards the front and not the rear of the engine. the area between your radiator and cam covers is safe for contact with water... further back you could short out your coilpacks, your PTU, etc.

I have this on mine and it came with a Cover inside for the vents for the winter and Wet days....But for summer i'll pull it out although in Scotland thats normally one day a year if we're luckly lol.

It's in carbon and was supplied by the lads at www.knight-racer.co.uk

there is too much crying go on on this site.... if you want a drop vent hoood get one.... its not going to ruin your engine.... i have one its fine and it actually has overlay fins which prevent a half inch of water from coming in..... of course if you are leaving your car out in some sort of flooding rain storm then you had better not get one haha

sorry this is the best pic i have of my vent. Hard to see but there are little fins that stop it from draining straight into your engine bay.... believe me they hold alot of water the hardest part is trying to get it all out after you wash it haha

[funkymonkey]

i guess it all depends on what sorta vents you're looking at... bonnets with drop vents let water thru easily while the raised vents like the two above have some preventative bits.

[NA_Goodness]

What about EVOs? They have bonnet vents that look like they would let alot of water in. Have a look under the bonnet of an EVO and see how Mitsibishi did it. If you can copy that then you'd be fine

[Fujiwara]

May need to talk to Peter about his bonnets.

Mate it shouldn't matter being a mechanic was washing engines with a hose a little rain mist wont hurt it.

just try keep water off your coils or distributor and major electrical bits
