The only thing I have to add about venting up or down is that pretty much -every- car that vents -up- is a dedicated, purpose built race car. For cars like the 914, 968, 996 etc, they are production cars first and foremost. The 917? Not a production car. 962? Not a production car. The GT40? Not a production car. And the new Ford GT is modeled after the GT40, so it retained the same external features.

Thorough engineering demands upwards venting from the hood??? Then I guess the team that designed the Carrera GT were just a bunch of know-nothing hacks?

Just pokin' fun at you Ahndy... But it -is- possible to design a car to vent down and not sacrifice performance.

Yes, the new Ferrari super-cars are upwards venting. Makes sense, it is capable of speeds that our 914's couldn't even achive in guided free-fall, and are not very liklely to see daily driver duty, hard to really call them -production- cars. Can the F50 even be considered for homologation? Were there enough of them built (<400)? I know there was a very limited number of Enzo's (400?). Hardly what I'd call -production-.

Okay, devil's advocate... The Lotus Elise is upwards venting, and it is about as close to a hopped up 914 as any modern production car will ever get. Still, I don't think it's essential to cut the hood, and I don't think you're hurting the performance of the 914 much by venting into the wheel wells or below.

I prefer the wheel wells... The air in there is generally pretty stagnant, so exchanging the brake-heated air in there has got to be a good thing. Even air that has gone through the oil cooler will still help reduce air temps in there by creating more tubulence in there and getting air to circulate. Add some good front mounted brake ducts and it's even better...

There, that's my $0.02...

Good point, Josh. I like that thinking...

Thanks, that pic was Labor Day 2006, you should see it now. I used to have better pics of the vent area can't find them, maybe will take more this weekend.

just be aware that as of my last reading of the SOLO-II (SCCA Autocross) rules a couple of years ago, cutting holes in the bodywork is not permitted in any stock or even Prepared class. Welcome to 'Modified."

When you consider the fact that the car is sporting a 1986 3.2 Carrera engine I would expect nothing less... unless you think anyone is dumb enough to believe that is a 2.0 six...

and I didn't respond to you.
I responded to the thread.
Anyone considering a body modification should be aware of the potential consequences - classification-wise.

last time I looked at the rules, you could still run up to 2,8 in F-Prepared.
hood or fender vents would move an otherwise legal car into Modified.

With a 3.2, that would put a 914 into SM2, or EM. I don't think you can cut holes in the body work under the SM2 rules, but you can under the EM rules. Heck, you can do pretty much anything you want under the EM rules. Oh yeah, you could probably also run under the XP rules, and hood vents would probably be legal in that class as well.

But again, if you're building a competition car, and are contemplating unique, expensive, or non-reversible mods. RTR... RTR... RTR.... That's "Read The Rules". And yes, read 'em more than once. What's totally innocent on the surface, could bump your car into a class that's populated by trailer-riding-fire-breathing-monsters.
