Stealth Engine Bay Heat Venting

[MAGONSTERZ68]

has anyone had success venting heat through rear inner fender wells?
i don't want to cut up my hood or outer fenders.
as i understand it heat currently vents through the side lower ports of the fenders just front of the firewall.
i wonder if cutting a section out in this same area and bending into flap to capture incoming radiator air flow and direct into outer fender well would assist without creating odd aero lift or push at higher speeds.

Hey
What about venting at top of fire wall out through cowl?
Just a thought as hot air always wants to rise
Cheers

i think that would work for low speed and stop and go traffic but if not mistaken the high pressure at base of windshield would prevent any real evacuation at cowl and may even intake fresh air when it exceeds pressure of the engine bay, suppose could induce fresh air at high speed.

You make a good point. I want to 3D scan my car and get into aero design.

I would test the pressure differential in the spot you are considering before doing any cutting. If you have good pressure differential it would work. If you don't then it's a mistake. I used a magnehelic gauge to do that for my hood vent placement.

have any pics of finished product?
thx

Finished pics of the hood vent install are here (https://www.autoxandtrack.com/trackspec-motorsports-1967-1969-camaro-hood-louvers-install/).

If you are asking about using the magnehelic gauage to determine placement then check out the post I made here: https://www.pro-touring.com/threads/82119-Chad-s-68-Camaro-V3-0-begins/page9?p=1147911#post1147911

What kind of car? If it has astro ventilation you might be able to take advantage of some of the existing ducting. It routes both inside and at the outer bottoms of the fender wells.

vents look great and seem to function well.

Mine are too but I used the kick panel openings for speakers and fabricated a blank off plate at the cowl to keep from building pressure behind them. If you left the cowl grill in place then you likely still have a significant pressure differential between there and the lower drain holes. Since it is that way by design, you may be able to take advantage of it.
