Info on Kelmark rear window scoop
Posted by: scottymac ()
Date: November 05, 2020 03:33PM

Dreaming of pairing Kevin Nash's new fan with a desert air set up to improve cooling. Kevin reminded me of the poor placement of the air intake grill on late models (as well as Phil's aerodynamics modelling), and I wondered if anyone with experience using the old Kelmark rear window scoop could relate their experiences? Any improvement in cooling? V-8, V-6, or Corvair 6? Hope Cody Hurley doesn't mind me using photos of his father's car for illustration? Old Clark catalog offering shown at bottom of that page. TKALP had one listed in an old, old link, sent a PM to him. TIA, Scott.

It looks like this thread never got much play. I'm thinking of putting scoops on an EM in the same location.

Has anyone seen this done? Seems like a "cool" idea..

Air needs to be "scooped" in the middle area of the engine lid, that's the "hi-pressure" area.

With a EM I would look for scoops like the Bill Thomas car. I have always thought they looked great. The problem is you never see them.
They give the car a real performance look. I would love a pair for my 61.

Hi Dwight,
Kevin Nash did extensive testing on airflow around a Corvair in this study. There's also info on the scoop used for Greg Lloyd's Bonneville racer.

For you and Troy, American Mel found a marine supplier that had something similar to the Thomas scoops, Beckson Marine. Look at page 2 of the link.

I wonder if something similar to that Kelmark rear window scoop, or those deflectors used on old station wagons to "blow" air across the rear window were placed at the rear of the the roof on a LM to "deflect" air down across the back window and into the the air intake grille at the base of the back glass might be helpful.
Something along those lines is sometimes used on modern cars. If it caught any air, it would also help keep the rear glass clean/dry.
IDK.

Art,
I had a picture of a Kelmark V-8 car that used the roof spoiler/deflector you mention, but I can't find it.
