Default Ram Air system

Anybody thought of getting something like thesedone? or actually anybody did anything like these? if so, what is the efficiency? I personally think these would bring you the most power from any other intake systems but may require a retune. I am no engineer nor a crossfire expert so these kind of designs may not be possible but from looking outside, it looked possible to me. If i had the equipments and the opportunity, i would give a shot and log it.

What do you think?

this is the first design, a new hood and you would have the air filter right after the MAF sensor right there so cold air would go directly to it.

and here is the second more like muscle car look, you would have a special design of air intake system which would stick out of the hood.

Yes I was bored

Might as well make the hood out of carbon fiber while your at it.

I wonder how much of a scoop you would need.

GruppeM are specialists in this area and manufacture ram air systems for a mutlitude of cars, although I doubt they cover the Crossfire.

The following website maybe of some use.

im not a big fan of a scoop on our cars but i think a cowl induction (one on each side of the spine) would look better and be functional as well. just a thought.

After thinking a bit, i came to realize 2nd design wouldn't be any good because on a rainy day, it would be ugly, however i think the first design makes perfect sense the car would have that mean look as well with that "efficient" hood scoop.

In theory, it would work. The only thing I'd be concerned with is the short path to the MAF with all that turbulence... might end up with a very irregular airflow and negligible overall performance increase.

According to the shape of the car though, wind certainly collects there in abundance:

This further proves that hood scoop theory would be VERY efficient. About MAF, i am almost certain the car would need a retune because airflow to the engine would be a lot more than what the computer expects so the car would probably run lean. A tune would take care of it easily. All you have to do is to put the car on dyno and start datalog it and balance the A/F ratio.

SRT is correct, a cowl induction would be preferred...

I think there would be too much turbulence that close to the throttle body...especially at high speeds...you can get too much air...but...that's just me...

Actually Musclefan, if you enlarge this photo you can see a cowl induction would work far better than most any scoop application. As I've posted before, scoops are mostly cosmetic, and the biggest reason I never chose to make mine functional.
Look closely at the 8 ribbons of smoke in the slipstream going over and under the car. Stream#1 goes under, stream#2 goes over the hood but seems to disperse (or disappear at the base of the windshield) into the cowl vent? Stream #3 clearly shows the gap of "Dead Air" that engulfs the entire car as it glides inches above the roof, and demonstrates why forward facing scoops need to be "above" the dead air to actually function properly.

Here's a good thread on cowl inductions, just don't kill the messenger for where it comes from.
Cowl induction for cold, ram air for the Si? - 8th Generation Honda Civic Forum

I do believe Forum member HDDP first experimented with it. Or had plans to do so.

After checking that out, yeah cowl would be pretty efficient as well. I can always reverse the hood scoop so the opening faces the windshield

Plenty of cowls to choose from here. A great opportunity for someone to show their mad fab props

Default Re: Ram Air system

just another thought, since our air filters are on top or our engines and there are two of them, why could'nt you make two cold air intakes that would hang down and scoop air from under the car. i have not thought of this in any great depth yet so please do not be too critical about this. i think it would work and eliminate the problems associated with running tubing thru the radiator support. water would not be a problem thanks to gravity. it would only be limited in size/dia. by the available space around the engine which has to be more than the small holes that are available in the radiator support. this just came to me after seeing the pics of the smoke line in the pic used earlier in this thread. no matter what anyone says our cars are

Talking Re: Ram Air system

When I altered the CAI design of needswings to make the dual inlet to reduce the pressure losses with other designs, I considered all other approaches, including the cowl. There was no filtering room available and the front of the radiator had as much ram pressure as you could get, I measured it to be about 1inch of water collumn and that is not much gain overall. Ease of installation and service / filtering made the difference for my approach. Symmetry also made the design flow well for the eye also. Enjoy, W Dy
