OK, got my hood on Thursday. I bought it to reduce under hood temps during stop and go traffic in summer, and to increase efficiency of the radiator by increasing airflow on spirited drives. It should work the same as cutting vents in the OEM hood, which I didn't want to do. I'm not expecting it to reduce peak oil temps but to aid in coolant recovery time between pulls during occasional canyon runs.
I'm leaving it unpainted (it comes with a clear coat) because it's an additional cost, it blends in pretty well with my DGM car, and if I ever need to return to stock, it's easier to sell an unpainted CF hood.
Observations - it's very light and rigid. The backing structure around the perimeter makes it stiff, and it doesn't feel flimsy at all. The rear corners are slightly high (maybe 1/8"), so I've let Joel know about that for future builds. No biggie to me. All the holes for the OEM rubber/plastic seals are drilled and the seals transfer over perfectly. I got mine with the tubes to direct airflow from the NACA ducts down to the coil packs, but I haven't installed them yet. There's probably no need to install them for daily driving, but might be nice to have them for canyon runs or track.
