DIY: Fang Vents: Forced fresh air to your airbox

bigaudiofanat · 07-13-2009, 02:16 PM

You should always have a filter to clean the air before it goes into your engine

Huh?...All this stuff is pre-filter. Doesn't matter what you have..Stock or otherwise. It's simply a means to get outside (and cooler) air to the filter inlet..

Don't know why people keep faling to realize this setup is NOT in place of filters...

Awesome write-up Mod. Definitely will be doing this once I get my next Z.

+rep to you sir.

Why wouldn't I do the same setup for Stillen Gen 3 long tube as was done for the brake? Actually asking about using the Shop vac aimed at the filter. That Shop vac bit was brilliant. I had been contemplating adding some vents in the nose until I saw this thread.

Just had the Modshack mods done for the Fang vents for the Stillen Gen 3. Just want to say thanks for the concept to Modshack. Kudos.

Looking to have the vents done soon. I am wondering how much cooler air will get through on a Injen CAI versus the Stillen G3 CAI being they are mounted in different areas.

You just need to aim the hoses or ducting at your filter. A left and right 90 degree angle off the fang holes, pointed toward you injen should work..

Thanks a bunch, I may pm you if I have any questions on the install or parts. I did check out your album.

btw...props in advance for this great contribution to the community.

Here is a slight variation that will save you $17 on installation.

I used 2.5 inch neoprene brake duct hose from Porterfield brake company. Rather than attaching a set of flanges to the air pass through I just jammed the hose directly into the airbox. With a little flexing of the hose it fits in perfectly.

The last picture is one taken with my cell phone directly into the airbox.

Oh, yeah. I also routed the hoses around the outside of the crash bar. This required removing the air deflectors.

Great finding! I'm going to try it with just two flanges.

any idea how much of a temperature difference this mod makes in the winter time?

And also, how does this mod compare to short tube and CAI?

Over stock, None as the OEM boxes are sealed to the radiator wall and pull air from outside the bay. Intake Air Temps (IAT's) will run 5-10 degrees over ambient typically, while rolling. That 5-10 degrees, as measured at the MAF, is mostly a function of the airbox and MAF being inside the bay. Both a Stillen G3 and my Custom short rams run roughly the same temps based on reports here. Open element short rams though typically will run 25 degrees+ over ambient. The hose will lower that a bit, but without completely shielding the filters they're still gonna suck a lot of engine bay heat. Mine are shielded and insulated so the impact there is minimal. During very cold weather I've seen the difference from ambient go to 2-3 degrees.

only thing i dont like is it looks like your sealing the ducting to the air box? making it the only way of air getting in. wont that basically make it have to suck through a straw to get air at idle and low speeds. though that doesnt seem like much but im pretty sure your hurting the performance through a good bit of the launching untill certain speeds are hit. ive seen setups like this and watched cars lose power because of that until certain speeds are pushing enough air in. have you actually had the car on a dyno with that setup? cool air is good an all. but it the engine is actually having to struggle to get the air its not helping. you need something to actually monitor air CFMs and see if its actually helping or hurting. but i could be wrong. but that happened to me and a few others on our grand prix bck when i had one. the intakes are very similiar to the Z other than only having one box.
we had places at the bottom of our front fascia perfect for ducting. but it turned out because of the length of tubing the engines were being starved of air.

My airboxes are not connected/sealed to the inlets. Even if they were, the flanges are no smaller than the actual pass through ports to the OEM boxes.
My experiments on another similar design (sealed) on another car showed that the flow up dual 2.5" hoses was enough to pretty much eliminate any restriction at the airbox outlet, and actually show some positive pressure on a Magnehelic gauge..
