Title: Vents
Post by: manta22 on March 07, 2017, 10:12:03 PM

The rear vents are finished so I cut out both L & R front fender vents today. At lunch a few weeks ago John Horsman said that I should add one more vent slot in top of the front fenders, the existing ones were too far to the rear. I followed his advice since he has spent a lot of time in the MIRA (Motor Industry Research Association) testing Ford GT40s, Porsche 917s, and Mirages (the Gulf Racing Mirages), and others.
 
To make another vent, I used a 1 1/2” hole saw and the HF body saw to make a slot in front of the forward most louver. This should make the anti-lift aerodynamics more effective.

Nice work (as always ) I wonder if you could whip -up covers over them..ala Daytona/Superbird to smooth the flow?/

Dodnyou hand fabricate the internal portion of the vents? Usually I see the "louver" stick up, that's awesome that it's an internal "louver"

The louvers were molded into the fiberglass when the body was laid-up by the factory but it's up to the customer to cut them out. As far as a cover goes, the depressed louver should have good airflow; I think a cover would disturb that flow.
