    Love Sy/Ty.... Would have bought one if i didn't buy the V.

    Also would love to see how the hood turns out. I wonder if there are extractors similar to the Spectre Works ones that could be fabbed in.

    As I mentioned at the beginning of this thread, you can find all sorts of vents and louvers if you search around. A pretty random example that I saw recently over on corner-carvers.com - the intake louvers from a 1970s snowmobile were used on an LS-motored E36 (they flipped the louvers around so they would vent out the back rather than act as scoops).


    One of my saved searches on ebay is for louvers and vents (I haven't bought anything in years, it's just one of those things I look at). There are hundreds and hundreds of things that pop up. A lot of them are garbage that I haven't figured out to filter out of the search results, but there are all sorts of things that one could be creative with.
    '05 Stealth Grey CTS-V, Hyper Silver Linea Corse Venetos w/Continental ExtremeContact DWs (summer), black Team Dynamics ProRace 1.2 wheels with 275/35-18 R-compounds (track), Hyperblack Rota Torques (winter), KW Variant3s, V2 front brakes, Hotchkis rear sway bar, EPS cam, TEA-ported 243 heads, FAST92 intake w/LS2 TB, JBA Camaro/G8 1-3/4" shorty headers w/JBA cat pipes, Corsa exhaust, UUC motor and tranny mounts, UUC shifter, MAPerformance trailing arms, Specter cradle bushings, etc...

    Re: So maybe I'll just make a DIY Heat Extractor hood

    The real challenge may be trying to work with all the structural bracing in the hood. I spoke to my body guy today when I dropped off the car and he said that sometimes areas of the hood need to be reinforced since it's a double panel and the thickness is variable. If you peek under the felt hood mat you can see that the V's brace panel looks a bit different than the BMW in AAIIICs picture. My guy has done it before several times but he says sometimes it involves more than just cutting out the holes. I'll try to get as many pictures of the process. The results will be interesting. I'll probably do some hood pins as well since the hood waves like a piece of paper at speeds above 130. My last track outing is October 13-14th at Road America so I can see if any of these changes work.

    If you go that route, use the aero latches instead of the pins

    IMHO, a much better use of time and money would be a ram air hood that would allow you to feed air to the intake through a straight pipe, doing away with that horrible 90 degree bend we have.

    No place to put the filter unless you want to stick it above the hood.

    Why not? Cut a hole, stick the filter in there. Filter will be protected by the add-on scoop.

    Cool hood on that Challenger, but in this case we're looking to take hot air out not let cool air in.

    I'd rather have the aero, handling, and cooling benefits of a vented hood than the few extra HP one would get from a ram air setup.

    To each his own, of course, but I've seen a couple of those Challengers in person and I think the scoop looks ridiculous. On a classic muscle car the same thing looks awesome (the 60s Mopars, for instance), but on a modern car it just looks completely out of place to me.

    Even a lower profile version (think WS6 TransAm or the GTOs) would look goofy IMO.

    No doubt, that exact implementation would look like shit on a V. I was just trying to convey the general idea.

    I disagree though that getting cool air through a straight pipe would lead to a negligible gain on a NA car. It doesn't even have to be a ram setup-- some hood scoop setups have the opening facing the driver.

    I stopped by the shop to see how they were making out. Holes are cut and vents are in place. So far it looks great. Next is to fasten the vents in so they stay put at speed. I may have some work in progress pics next week. Hopefully completely done by next Friday.
