tuft testing

Yes, I have some literature discussing the misapplication of these
submerged NACA inlets. Unfortunately, the previous owner/builder
installed them because the original scheme(s) were apparently worse.
I am willing to tradeoff a little extra drag for better cooling... I
am just not certain yet how best/easiest to do it.
I'll try the naptha.. thanks.

Interesting. I'm sure you have researched the data that shows NACA
submerged inlets are poor at cooling applications, where the pressure
required for good flow, are relatively high?

Wouldn't a scoop, ala upside-down P-51 scoop do much better, with low drag,
also?

Did you try naphtha, (lighter fluid)?

I made the mistake of leaving duct tape on a vehicle too long once, and I
commiserate. Slow steady progress with plenty of naphtha and paper towels,
was my best way out.
