Hood vent orientation?

I replaced the prop rod with a pair of gas struts, partly because I had them with the hood before, and partly because I’m going to have to cut the prop rod hole out for the center vents. I ran out of reinforced cutting wheels, so further progress is either going to be painstakingly slow or I’m going to buy more wheels.

Looking good!

Did I miss something? Where are the test results discussed?
Without any testing, IMO, this is just mainly becomes a "Cosmetic" exercise.
I also would have suggested for this application a differential pressure gauge be used, to find the aero sweet spot faster, ie two tubes measuring inner and outer pressures at the same time, and conditions.

Hell no, why would any one want to do that? After all, it's only 16 years since I first (as far as I know) published on the web how amateurs could use this technique.

At least some people did suggest in this thread that he do some pressure measurement, so I suppose there is progress!
