Contour Enthusiasts Group Archives Forums Modifications Duratec Performance Stock SVT Air Box

Did any one disconnect the fender hose to the end of the stock SVT air box first before they bought a KKM or other after market filter set-up?
I ask because when I went to the SVT filter from my original standard V6 one I wasn't happpy with the sound until I disconnected the fender connection
Also from the "Muscle Mustangs +Fast Fords" magazine article from Sept. 1998 on comparing a stock SVT to the Bondurant Driving School SVT they write (next to a picture of what appears to be a stock air box set-up of the Bondurant SVT) "This unique air duct replaces the stock silencer and directs air from the fender to the filter box. We removed the stock silencer on a production model and picked up 2 mph in drag strip testing, so this setup must be worth 15-20 horsepower over stock!
I removed the connection before I re read the article which I saved and while I am no Dyno it does feel more powerfull and sounds better to me.

Sounds intresting. I'd like to see it dynoed and I would like to see a copy of that article.

Although the SVT air filter and air box is very free flowing, the part into the fender looks very restrictive. I would be interested in learning more about this.

:rolleyes: Oh man...

There is no stock silencer on the SVT.

The fender draw boot pulls in colder air from the fender instead of the engine bay.

It's outlet is the same size as the stock airbox inlet so removing it would show Zero gains outside of maybe raising the intake air temperature slightly on hot days....

BTW - if an open air filter shows maybe 3-5HP how in Hades would doing nothing (removing boot) show 15-20HP & 2mph???

I don't even know if the magazine is still published. My intent for removing the fender draw was to get more intake sound. Now driving for a few weeks, its a little too loud for me and will probably reconnect it soon. The HP claim is the magazines not mine, I doubt it's what they claim.
