Hood scoop

[skvitt5]

Hey, folks.
It's been advised in multiple threads to remove the plastic cover from the engine, and partition walls to promote air flow.
Wouldn't it be logical to install a hood scoop? Has anybody tried?

I wouldn't recommend removing the engine partition if you park the vehicle outside or in rain. The engine partition keeps rain off of the back of the engine. Over time the water damages sensors, coil packs, etc. The engine isn't designed to have water on it all the time. Its a well documented side affect of removing the partitions or having them disintegrate and not be replaced. Removing them theoretically improves airflow under hood.


The engine cover is for visual purposes and sound deadening and can be removed. Though there is not a performance advantage, it MAY increase the life span of the oil and coolant lines in the engine V.

its removal may cause rest of the engine compartment to overheat and damage hoses and wiring outside the engine V

I would rather trust the BMW engineers then amature enthusiasts.

Well, this entire N63 issue shows how trustworthy BMW engineers are...

It is not the BMW engineer's fault that people use a 400-450 hp Twin Turbocharged , 5000lbs ,2.5 ton vehicle, for soccer mom milk runs and stop and start city driving.

A Honda Civic or CRV would be better suited.

It didn't come with a caveat on how it needs to be driven. There's also nowhere in the manual that says the truck needs to be driven a certain way for it to last past 60,000 miles. That said, I agree...

Better than a hood scoop in my opinion is to get downpipes, wrap them and throw on a turbo blanket. Underhood temps are night and day after and after driving the car hard you can put your hands on the turbo blanket. I am thinking I should check the underhood temps vs stock now. I've been trying to mitigate the heat issues for awhile now...

Neither do the manuals for Porshe, Ferrari, Lamborghini or Bugatti .

I think those manuals specify that you MUST drive them to Starbucks, Rodeo Drive, and anywhere in La Jolla.

Sorry I missed this thread....ALL the vial bits are under the damn cover...Geez man, if the N63 was the epitome of reliability that would be one thing but its a FUCKING JOKE all due BMW's complete lack of understanding on how to properly design a engine compartment with a HotV.

I mean wow, just wow. Class action law-suits, multiple recalls...ya lets trust em, they clearly designed this one PERFECT!!

Look here it is in a nutshell: BMW Engineers are made up of teams, some are brilliant, some clearly sucked someone off to get their jobs. I will let you decide which team designed the thermal venting of the N63 and the AWESOME idea to put a damn engine cover over a HOTV setup. BMW knows they had a huge issue, later versions of the TU have redesigned thermal shields. In their defense, the N63 was the first production hotV for any make... and it shows

And that is the Crux of the problem, its a SUV with a race engine but it isnt marketed as such...BMW should have known better these would be in stop and go traffic, it is complete failure with BMW on every level and they know this and thus why it has cost them to replace all these engines.. the messed up big time in the design. A few tweaks can greatly extend its life however

the Rain gutters are what direct the water and should be kept, the rear partition has a very minor affect but it is true some water will leak in but its minimal at best as long as your gutters are intact and in good condition.

It WILL leak in engine fumes and possible Carbon Monoxide (if you have an exhaust leak) into the cabin if you have outside air on so removal is not recommended if your engine has issues in this manner. BUT TAKE OFF THE DAMN ENGINE COVER.

Got side tracked with all of my ranting (I am very passionate about trying to extend the life of the N63 if you couldn't tell) that I forgot to address your original question.

I am going to add vents much like the Vorsteiner Hood has (not sold anymore). I think it looks awesome and will actually help with the under hood temps even more.

Also as 9vapors mentioned, wrapping your exhaust makes a huge difference too, I wrapped everything (downpipes and manifolds). It is quite a bit of work though.
