So I'm ordering a non functional scoop on friday and I plan to make it functional. I already have someone sending me a stock airbox/tube so that I can use the little module plug in areas on a new tube that I create. My question is this...Do you guys/gals think it will be more beneficial to create a new box that will use a square K&N filter and have air brought into it close to where the scoop will open up or should I use a cone filter that has air directed towards it.
I'm thinking that if I create a new box and use a square filter I can force more air into it than using a cone filter but I'm not exactly sure until I start the process.
Also what should I expect in the gain departments having true ram air and a custom tune over a CAI/tune located in the stock location.
Thanks for your opinions! Much appreciated.

 

I wouldn't expect much in the gains department. I have the shaker system on mine. CDC at one point claimed you would gain 2% hp with this ram air system, but someone on this site dyno'd their car before and after installing it and they actually lost hp.

 

Neo-shaker CAIs on on modern FI Stang's really don't make much sense, functionality wise, as they did on carburated old school Stangs. Several problems with a shaker CAI on a modern Stang:

Unlike '60's era Stangs sucking furnace-hot air from the engine bay, modern Stangs already get their air from the relatively cool fender/front area.

A shaker CAI has necessitates a rather tortuous intake path to work, which can only increase intake resistance some degree or another. In the '60's car, with the carb mouth right below the Shaker system, it was a short, direct shot down the maw of the carb barrels.

Boundry layer issues: airflow close to the hood is often rather stagnent, velocity wise, especially toward the back of the hood. This is why more effective hood scoops poke up in an ungainly manner, above the boundry layer. Indeed, as early Firebird T/As showed, it was often better to have the shaker opening pointing BACKWARDS, taking advantage of the high-pressure area at the base of the windshield.

Thus, as you noted, you're probably more likely to see a net decrease in performance with some Rube Goldberg neo-shaker system.

So basically, shaker CAIs are 9/10s pose, 1/10 function. If you're really serious about performance over hollow image, use a front mounted CAI that takes much better advantage of the engineering specifics of the Stang's current FI intake system than trying to clumsily relive the past.

Probably a more effective hood mod would be to include some venting to release hot air and, especially, underhood pressure. Some of the first S197 racers actually blow off their hoods down the straights -- ripping them from their mounting hardware -- due to such high, high-speed underhood air pressure. While the Stang's '60's style tall, reverse prow my look sharp to the eye, it looks barn-door blunt to the wind. I think the GT-H does this, as does the GT500.

Of course, your car, your choice.

 

Well of course you wouldn't see any gains on a dyno... the car is sitting still; the air isn't being rammed in.

However, as was stated, the ram air effect even for a moving car is negligable at best.

The Camaro SS and Firebird WS6 only claimed an increase of 5hp (315 --> 320) if I recall correctly. I doubt it was noticable and that increase only happened at speed.

 

What about ignoring the scoop and trying the WMS intake?
