Smoothing the cowl vents

one2gamble · Nov 12, 2004

when the cowl vents are shaved where are these people getting the air? Engine bay?

The only purpose of the cowl vent is to bring fresh air into the interior of the car. This is where the heater box and the driver's foot vent get its air supply from. Shaving the cowl vents will render the heater and driver foot vent useless.

The engine gets cooled through the grill which blows on the radiator. Also alot of air comes in from underneath the vehicle

If your doing it because the inner cowl is rotted out, then the heater/defroster will get it's air threw the interior(rot holes), however the VENT will not work.

its being done purely for looks but I didnt want to render the plumbing completely useless and was wondering where other people got the air from. Its not a big deal, we will figure it out just thought I would ask.

Well there are drain holes in the 2 ends under the fenders, you could cut them out larger and get your air form the wheel wells behind the mudflap.

Since it isn't air tight, won't you just recirculate cabin air instead of outside air?

It is suppose to be airtight. Depends on how much rot it's got.

You got to love this "rot" stuff.

I have seen some with holes drilled from inside the engine compartment into the cowl area using a hole saw. About the only way to get air in there but in talking with these individuals they did pick up some fumes from the engine bay.

thats what I was thinking historic, though something a little "cleaner" than just some random holes..thnx and the cowl area is far from air tight, the damn thing has holes in it.

I may try and see if theres a way to get air from the fender area. Anyway thnx everyone.

Yep, you can cut some holes in there and then "outline" them with metal to keep things stiff! The ones I have seen at the track actually look pretty cool.

just an idea, but if you did this, then drilled holes in the rear fender aprons, couldn't you connect the two holes (per side) with some flexible hose? between that and sucking air from the drain holes, i think that would provide enough flow. or i could just be an idiot.

You are not an idiot but we might need some engineering help here. Not sure but you might actually create a reverse air flow and air be sucked out of the car.
