Ram Air CAI For hood Scoop Hoods?

Water drops aren't really the best since they adhere to the body but it would give you a good indication of disturbance. The only real point I was trying to point out is how an active hood scoop could influence the outcome. But overall you are right on the point!

 

Ok, I lied a little. I don't think there's any bugs in there now, but I always need to wash them out when giving the truck a bath. And it's raining out right now.

 

On topic... I was also thinking, could the fact that the scoop isn't functional (basically a cave) be aiding in the large bubble on the hood? Or is it very similar on the regular hoods also?

 

May not aid intake performance but certainly raise testosterone and adrenalin!

Are you smearing peanut butter in to the mesh?

 

Bugs are heavier than air and it takes a little "lag time" for the change in air/wind direction to move the bug up and over the scoop and windshield.

 

Also, I would agree with chris4x4, making the scoop functional would probably not be worth it in the end...

I study air movement accross crop surfaces (corn, soybeans, hay/grass, sometimes buildings), vertical wind is our main emphasis. The front of the vehicle is a bluff body, it deflects wind up and over the vehicle. The larger the bluff body the more deflection. A lower profile car could probably benefit from a functional hood intake. A truck with a large grill/front end will deflect more air up and over the vehicle.

 

Do you have a better idea?

 

To attract bugs?

 

its a similar but almost opposite effect that you see in aircraft aerodynamics. with stagnation points and separation, in road vehicles lift is an negative. not only because of the obvious reasons of it being the opposite force to down force or "weight", but also because lift also creates drag. in aircraft, im sure much in the same way as in road vehicles they try and balance this trade of between lift and drag given the application and the purpose of the aircraft i.e. the purpose being for high lift or for speed. like you said before a high performance vehicle is going to spend much more effort relieving the force of lift to limit drag and allow for more down force. other vehicles i believe you touched on this earlier, and more towards the point of this thread, use this side effect of lift to an advantage. however, in aircraft there are often "tabs" on its surface, you can notice them looking out the window next time your on a jet liner, that's purpose is to keep a laminar flow along its surface by alleviating any stagnation and helping smooth airflow to harness lift to its full potential, as the separation point (on a wing, starts towards the back of the top side of the leading edge of the wing and works its way over the leading edge as you increase the angel of attack) once it reaches a certain point on the leading edge it causes stagnation of the airflow over the top of the wing and induces a stall. the drag itself comes not only from the force of the lift but as the air flows over a smooth surface it naturally "sticks" to that surface, the air that is actually in contact with that surface creates friction and therefore more drag. on an aircraft this is a necessary evil. but in the description earlier in this thread it looks like a car is almost creating in effect an induced "stall" over the hood to separate this laminar flow and cause stagnation to reduce drag and lift.

 

Great thread guys. I have been super curious about the idea of making the hood scoop a functioning air intake. All the info has been really helpful. Does anyone know if you can mount the Volant ram air scoop to the stock intake?
If not, is the volant CAI system worth the money?
Thanks guys
