Both hoods (the original Autokensinzxnxonzaz copied) I posted above had dremel surgery to clear the VC. it's fun to cut fiberglass, it's like butter and makes a mess, very satisfying.
what;s said is I bought that extractor in Nov of '07 with the hopes of getting it molded to my hood....sigh. Now everyone is going to have it and I won't be the cool OG with it.

I am seriously about to pull the trigger on the Carbontrixmegastylin hood scoop thingie so I am interested in status as well. That CR extractor hood group buy is getting nowhere in a hurry. And, whether the Autokonexiondriftingbuttsex hood sucks or not, it is more than I want to spend.
I need one for an NA BTW. The NB is being relegated to street duty so no need.

^^ Those cars are damn sexy. I admit it, I have an erection.
EDIT: You know of course that kind of hood is really not possible on a front-engine car.

this is something that would work though assuming the vents are moved off to the outsides of the hood like above the headlights all the way back. Also according to that image thats where the lowest pressure is so even better.
now i wonder where is the highest pressure underneath the hood in the engine compartment.

From Perryrace:
V8Roadsters.com • View topic - 99 Miata LS1 Build "Twice as Nice"
"A small hose is connected to the gauge and then the end of the hose is positioned at 90 degrees to the air flow being measured. I therefore attached one end of the hose to the gauge and the other to a pole. We then drove down the highway at 60 MPH and mapped the pressure across the hood (hood was on a 94 Miata).
We then mounted the hose end in front of the radiator, and then behind the radiator. Again all measurements were taken at 60 MPH. The front of the radiator was measured at 1.25 and the rear of the radiator was measured at .65.
Therefore the pressure difference was .6
You can see here that there is still a positive pressure behind the radiator. In an ideal world there would be negative pressure behind the radiator. This would then draw air through the radiator. We thought that we could improve the air flow through the radiator by utilizing the low pressure zone as mapped on the hood. "
"So it was time to cut holes is the hood and see if there was a difference. I had a hail damaged hood on hand and utilizing the pressure map above we cut two holes in the hood and then measured the results.
Pressure behind the radiator was now at .22 (vs. .6 above) or a difference of 1.03 (vs .6 before the holes)."

Make this, in FRP, for $200ish, without headlight lids, and I will buy one tomorrow.
Mold it without headlights, but leave the little lines in. If someone wants headlights, they buy a scoop and stick it on their stock hood. If they want it molded in, they cut the headlight lids out and use it. If they want to **** tens, they run it with molded-in headlight lids and ditch their 6lb-per-side headlight buckets/motors.
