Hood came unlatched on highway

[davem]

lmao this happened to me in my old car (not bmw), the thing had a wicked rad leak and I was shopping for a replacement car so I didn't want to put another cent into fixing it. I had to constantly top it up and I must have left the hood unlatched as as soon as I got up to speed on the freeway it popped up and cracked my wind shield pretty good...

O I got a replacement for 48 dollars with tax.

actually, no....the hood is shaped like an airfoil or the wing on an airplane since it is curved. as wind travels over the top of the hood it accelerates due to the curved shape. this creates a low pressure area over the top of the hood thus pulling it "up".

Really? But what about once the hood starts to open up to much? Once it gets to that point wouldnt it shut agian since all of the air is hitting the flat surface of the hood?

Lmfao makes sense. Good day sir

Its a 318ti. I forgot we're all thinking e30 here. At least on an e30 its super obvious is the hood has been left popped open. Also I can't drive to the junkyard without a hood because its too far away and its snowing.

Also I was mudding with my new-to-me LSD to get into my garage. Pretty awesome until your snowies get filled with mud then they are basically slicks.

Even if the air built up under the hood it would stay shut because of the air traveling over the hood.

Pressure on both side but not static and clearly not equal

i've popped my hood open on the freeway when my car was overheating.

how this would cause damage.... i am not sure.

Drive to the junkyard without a hood on your e30, attatch new hood at the junkyard, drive home with new hood already already on the car

I've done this, well I actually took off the old shitty hood and left it in the parking lot.. :)

Lucky you're not dead. Forgot to latch my datsun pickup after futzing around with its weber carbs and took off down a steep hill in Ocean Beach and smashed the crap out of my windshield and caused my buddy to crap his pants.

Unlatched hoods can cause you to crap your pants.

I too am confused how you damaged your hood.

this is a B saint thread after all.
