Are vents worth $1000?

School me on these blowers. I want to add them to my car. I noticed that I get a heat gun out of the vents until I drive 50 MPH for 5 minutes or more, then they cool down. With blowers, it should be "cool" all the time. . .

Where are they installed? Size? Brand name? Whatever you can tell would be great!

first , you have to insulate the ducting. Mine has cool air at any speed( well at least ambiant temp air) . A blower from Mcmaster Car or one of the boat supply companies is put in line in the ducting. Also look on EBAY, a lot of racing companies sell them for cooling brakes. The advantage of the blower is of course to blow high volume air when going slow, when you need it most.

I looked in Mcmaster, but what am I looking for. What I saw there all looked huge to fit inline. How do you insulate the pipe/hose? I assume just the area above the headers?

I installed a 140 cfm 12 vdc vent fan with a 3" duct into the dash where it split into two 2" ducts. One for the driver side and one for the passenger side. I did this just before we drove to the LCS. I tried it a couple of time and just got hot air. My foot box does not get that hot but you know how it is. Coach Mike install one in his Cobra so I had to install one in mine. The jury is still out. Mine cost about $120.
As hot as it gets in Alabama I need an aircondition.

North Alabama, is has been 90-95 for weeks.

I have both drivers side and passenger vents. With the top down in So Cal weather I don’t see the benefit. However, when I put my Hardtop on my KPM500 Lemans it really helps.

The valves on the bulk head are from an Mg midget heater box.
I paid £10 to replace the one I had missing on my cobra and got a heater with it
The front intake ring is Daimler/sunbeam standard part cost me £8 and matches the other original side
