hood scoop for turbo?

[DeleriousZ]

i was sittin on the can the other day thinkin about cars when this crossed my mind.. what about putting a fully functional hood scoop right above where the turbo sits in the car so the air flows directly onto the manifold and body of the turbo.. think that would do anything for the life of the turbo? maybe keep it a bit cooler? just a random thought

that has been done a thousand times before. Alot of drag cars utilize hoods or bumpers like you are describing. I think it would be a poor decision to do that on a street car driven in the elements.

yeah you see it all the time on turbo drag cars. If you live in a really dry place then it would be cool though.

what about all those scoops for the tmic on wrx's and such?

[scallywag]

I saw one on a 1250 hp supra once. Don't know if that would be very smart for the streets though. I think the reason the wrx and sti have the scoop is because they throw the intercooler right under it, well right on top of the motor. My buddie just got a 04 wrx and that is where his intercooler was. But as for like the outbacks and such that have the scoop but no turbo, it is just for looks.

That is for the intercooler on a wrx. for a turbo, just get/make a CAI to get the intake piping out of the engine compartment. A scoop won't really do crap for anything (Looks cool though)

I still don't think that would be a great idea for a daily driven vechicle unless you live in a desert. If you were boosting even just 10psi and submerged the intake pipe under water, you would most likely be shit out of luck. Even with a bypass, 10psi is alot of pressure.

oh I agree totally, scoops are just things to make a car look better ( as far as street cars are conserend) scoops have to be absoultly huge to accually function under 100 MPH ( If you want the math, I have it.)

I dont think too much of us live in fear of driving through 1 or 2 ' of water to really worry so much about sucking up water. I mean come on people...use common sense. It looks deep DONT drive through it

Go put your car on a dyno, boost 10psi and put your hand over the intake pipe. It is ALOT of pull. If you even go over a small amont of surface water, it can splash into the pipe and it will be sucked through the intake charge. There is very little to be gained using a "cold air" setup on a streetturbo car, just use a good intercooler. The air is going to be heated ALOT as it passes through the turbine, so just keep the filter in the engine bay close to the factory location, you are risking your engine over <10 deg.

Trust me, I have hydolocked a b16a with a CAI (no bypass) just by driving in the rain on I-95, b/c there has a small amount of watter puddled on the interstate, not a pretty signt unless of course you like connecting rods protruding from the side of the block.

how about getting a vented hood ie. vis invader for over all engine compartment cooling purposes, driving my cousins integra with a vented hood, i can see the heat waves coming out of the vent, but yeah i too am concerned with the turbo sucking up water on rainy days

[DeleriousZ]

no no no, not for the intake... just to circulate air around the engine bay... like, blowing air directly on the actual manifold/housings/downpipe... i dunno possibly keep the components slightly cooler?

sure, it does help. my hood is vented just above the manifold, its def not going to hurt anything.

[DeleriousZ]

eeeexcellent.. time to whip out the jig saw and go to work on my hood!
maybe later..

haha, no but seriously, wouldn't a scoop have the same effect only the air is forced downward when driving? i don't see how the elements would really affect anything.. unless maybe your intake was RIGHT there...

Most scoops, yes, they won't do diddly squat at low speeds. Something like a NACA duct, however, is actually quite efficient at pulling air in, even at lower speeds. If you have the turbo sealed off and only drawing air from the duct, it just compounds on that and can get you some real power gains.
