Air Vent for A/GC

Help in a last minute rush get ready/ The rule book states that there must be an air vent for closed cars which can blow fumes away from the driver.

On the #974 we have two oval shaped holes cut in the lexan windshield that are approximately 1" X 5".   They are located near the top of the windshield near the corner on each side.  Hooley drilled a hole on each end and then cut a straight line top and bottom to connect the two holes and make the oval shape.  If you have a lexan windshield you might consider this option.  We got this idea from the BMR coupe when we were faced with this problem.  I might be able to find a photo of the holes if you need one.  If your windshield is glass, I am no help to you.

Most windshield glass is safety glass.  It usually has a couple layers of film that hold everything together in the event of a break. 

For the OP: Anything will work for a forward facing vent.  Remove a side view mirror?  Build a little scoop that directs the air through the hole where the mirror used to reside.  A lot of times the stock cowl vents work fine.  Just make sure they don't open up into the engine bay.

On my coups I made a small scoop and put it on the roof just above and forward of the driver. You could almost stuck your nose in there if you had to. I did this after Joe Locosta gave me a talking to about the need foe such a device. he probably knew.

Forgive Mike, folks -- he races a pickup truck and therefore can't be expected to be really sharp so early in the morning.

I like to see the looks on the roadster guys faces when I ask them to show me their forward facing air vents.  Man some guys can't take a joke.   :-D  I guess tech inspection is the time to be light hearted.   :-P

Another option is a rotatable vent used in private aircraft. If you have lexan/polycarbonite side windows they are easy to install. Most aircraft parts stores at airports have them or contact Aircraft Spruce. Good Luck..........
