2nd round of testing results.

My main goal is reducing front end lift at high speeds since I have no cooling issues at this point.

I ran the next testcase by having the temps from the last testcase to compare to.
I sealed off the hood's openings (all 8) and re-ran the same tests as last time on the same day so the outside temps were just about the same.

At this point it looks like this high dollar extractor hood is all show and little go for the temps reported in 2nd round of tests were the same as when the hood holes were open.

I was able to determine if front openings were extracting air by using longer lengths of yarn.
Clearly at speeds about 50 MPH the yarn was being forced towards back of the car but all it seems to be doing is extracting the same air as the inlet openings and very little of the engine bay air is being carried with it.

More tests to follow.
