After making a air box for my JWT popcharger, I wanted to get more cold air, so heres my 2nd homedepot mod air induction to the popcharger, I will shoot the scoop flat black and you will never see it, after a hard drive I notice the heat shields over the filter were warm not hot, this mod works great all the ducting and scoop is ice cold after a ride meaning it works.

for thos who didnt see my original thread heres the JWT popcharger box

 

I actually think thats a good idea. A lot of people were dissapointed with the results of a CAI because the longer tubing canceled out the gains of the colder air. Thats why most people agree that the popcharger is the way to go. But in your setup, you are using the shorter tubing of the popcharger but still trying to get it extra cold air from down low. Also, this has no risk of water getting in the intake because there is a break between the cold air part and the actual intake.

That being said, I don't know about the actual materials used. It just looks like it would be loud as hell when you drive and make a ton of wind noise and rattling etc. But I could be wrong about that. How does it sound when you drive it? Do you feel any kind of power difference from the extra cold air? If this idea works, maybe something similar would be manufactured but with more conventional materials and a little cleaner install. But overall I like the idea....seems like it might work...good job!

 

yeah it was just a rough install , wanted to test theory before quality, there was someone else in here who had a nice set up, but if you were to shoot the scoop flat black it would be barely noticeable , and no wind noise.

 

We did something like this a LONG time ago on a buddies VR6.

For a Saturday afternoon, with which we were bored... it (home depot cai) and beer made for a lot of fun.

 

Keep an eye on water temp, could prove to be problematic in the long run

 

Any improvement in engine response? That would be the entire point of this wouldn't it?

 

i noticed more response with stock air box . heat shield on the jwt popcharger was extremely cool( compared to before the duct) after hard runs

 

I think you be better off leaving that part of the airduct open mainly because that is a high flow area. Any partial obstruction will disrupt airflow. Try creating a secondary airduct instead and run it behind the bumper, under the driver side headlight. If you remove the bumper you will see what I mean. Here's how I did mine:

Z8M i like your idea, what materials did u use?

 

(2) 4" 90 degree elbow PVC pipes, tapers to 3"
(1) 3" 45 degree elbow PVC pipe
(1) 4" aluminum dryer vent tubing
(1) roll of aluminum foil "Mastif"
(1) weekend afternoon with 6 pack .. Enjoy
I like Big Ern's idea on the aluminum sheath enclosing the filter. I might try that..

 

I had a setup like this for my old Civ! I always felt that the car was faster, although it might've been more of a placebo effect. I tell you though, you really get a sense of accomplishment when you're finished with a true DIY like this

 

Still not as clean as your install, but I was bored
