Wrapped my intake tubes with heat reflective tape.

NIck T , awesome data points, that surely took a lot of work to set things up.
my car brain pulls 6 degrees of timing over 140 degree F….so i am trying to get brain to see temps below this…..
I THINK I will focus as RKD suggested and just shorten the path to the throttle bodies….looking at the cowl now….
thanks for all your replies except randy and hacker of course !!!

There are pictures in "Project 928" that show some early 928 prototypes with air intake vents like you describe.
The best answer is to shorten the distance of air intake travel similar to what we do on jet aircraft engines. For some reason Porsche engineers designed the flow system to traverse the entire engine thus collecting heat over a long distance.
Better design would have been functional "side" air scoops adjacent to the air cleaner/intake along each front fender.
Shorten the distance you shorten the heat absorption while increasing air flow into the engine.
Just my opinion.

For a street car, I would not put in a lot of effort. For a track car, I'd be looking at air from the cowl windshield area as well as working on lowering under hood temps and insulating the whole intake path.
What might be fun with a efan, put a flapper on it so WOT it boosts intake pressure, and hard braking it vents to the rotors
