Cheap Ram Air
 

:flamesuit on: OK I put pvc in my car. :flamesuit off: I noticed the OD of the vfad was a good fit with 3" pvc. So I fabed up some ram air with two 90deg (one street bend for the bottom), some straight pipe (lowes sells 3' sections), and a pvc coupling I had lying around. I drilled and taped the bumper to mount the inlet. I also cut about 1" off both ends of the bottom pice to bring it up and back from the bumper. :) http://i137.photobucket.com/albums/q...8/P1040219.jpg http://i137.photobucket.com/albums/q...8/P1040224.jpg Comments welcome good or bad. :uhh:

I did the same thing ! until i bought my aem CAI

i was looking forward to adapt a bigger inlet like an oval shape and retrofit it with the center black grill

but i couldnt find anything



Nice one though

So is the last piece one or two parts? That is funny considering people pay $300.00 for the same concept. Is that rust I see?

Thanks revamp . 9k The last pice is the factory inlet inside the elbow. Its a little louder now without that cloth like thingy. yep thats rust. I drove her the end of the first winter. damn salt!:icon_no2:

That is awesome! I was going to use the same stuff for my CAI, but the only reason I didn't was that I wanted 3.5" OD metal tubing for my maf sensor. I should have used this for the rest of it though, but bought all the parts from the same place. Yours looks good!

Thats funny... I thought the VFAD and the intake resonator was the only thing really keeping the sound down.
Maybe the acoustic sound of the engine is bouncing off the PVC and amplifying the sound?

Interesting. So far it's one of the better looking home made set-ups I've seen.

good job - like it

can't remember if the long section is the high rpm or low rpm . If it is the low you may want to jam the valve open so that it actually works :)

I also removed the baffles in the intake box.I think the airbox is what kills moast of the sound.

Brettus- the vfad is on the short side (high rpm) I drilled a hole on the right side and screwed the flap in the open position. I also disconected the plug for it a while ago.
Thanks everyone:)

What valve are you referring to... the VFAD? If so, jamming it open won't do any good.
Plus, the PVC is not running into the duct where the VFAD actuator is, that is the fresh air duct.
The VFAD flap & actuator is the short straight piece seen in the first pic on the far right side (you can even see the brass actuator sticking out of the right side of that duct).

Ummm... removing the baffles was for better airflow through the stock air box.
The VFAD is for sound suppression until 5500RPM.
And the box on the accordion section (before the throttle body) is a resonance chamber.

OK... so I went back and did some reading (always like to double-check myself) and I did read a thread where MM mentions that the stock intake baffles do help with sound... so you were right on that.

The airbox mod... genius... PURE GENIUS! I wonder who came up with that, he must be the bestest most awesomest person in the world. :)

Looks great. Wouldn't the PVC be affected by the heat ?

I wouldn't think so since its outside the engine bay... now if it were inside, maybe.
PVC's upper temp limit is ~140F. Now you could probably get away with CPVC which goes up to 220F.

I kind of want to try thing only with metal pieces.... then sell them ahhaha

metal will look nice but bring the cost up. I spent under $20. the racing beat pice works great it usees all of the avalible space and its lightweight plastic. Also it all gets covered anyway.:eyetwitch

stupid question... did you have to take of the bumper to do this?

Yes... you'll need to take it off just to get to the two bolts holding the fresh air pipe (the section he replaced with PVC)

bringing this one back :)

did you notice any benefits with this besides sound? lower IAT's? less heat soak?
sucking in small animals or woman cloths?

Nice job :aroused: But I think adding a metal screen is good for daily use.

Nope not much. Got to drive along side it with my wife driving. Had to ask her if she had it floored cuz it sounded good.:D: My scan tool is old (no CAN) so no temp readings. I cleaned the filter once since then and its not that bad (bugs/dirt). Oh and BTW the factory grille keeps the big stuff out. :)

haha did something similar to this a few days ago, no problems with heat as everything is forward of the rad lol

#1, you have to be aware of your car. Not may can connect to a motor vehicle.
#2 it's only for high speed, that where you feel the difference.

one of the better looking pvc systems!
