Its "different" to say the least lol. nothing I think I would personally attempt.
Let me ask why it is that you need to cut the hood in half though?
I wan't going to cut it in half. I was going to cut a 12"-long section off the back, clear across the hood's diameter, and re-attach it with a hinge that would allow pressure from underneath to force the backside of it up, at speed, creating an opening from which trapped, hot air could escape.
if your goal is to have it flap up to release air then why not just cut an elongated rectangle in the hood towards the back of the hood and either have a permanently mounted windshield facing vent.
or stick with your idea of the flap design but just by cutting an elongated rectangle facing the back side of the hood.
That's exactly what I siad I would do, but replace it with the hinged piece so it wouldn't rain in (or, be visible from the other lane. LOL!)
Honestly, i think it may appear a bit gaudy and I would try to find a different way to accomplish your same goals but without it being as obvious.
I don't think a piano hinge, (have you ever seen a piano hinge?), which would be painted the same color as the rest of the hood, would be visible, much less obvious, from the next lane.
for instance, if you are concerned with wind from under the car filling your engine bay and creating drag on the car then I would get a sheet of tin and fab up an under carriage cover and mount it with nuts and bolts to stop wind from gaining access to your engine bay. so wind is good though as it helps keep your engine compartment cool.
Now, that is a great idea!!! Gotta look into that!
I don't think I would worry to much about pressure created from your fan cooling your radiator.
It's not the fan; it's the air that comes IN through the radiator (picking up lots of heat) that concerns me.
as for the flap flipping up to act as a spoiler to push wind over your windshield......you already mentioned buying an aftermarket fiberglass hood to cut to accomplish your goals, why not buy an aftermarket fiber glass COWL hood that will do the same?.....it will push air up over your windshield and give some slight down force I suppose and it will act as an engine bay vent.
I want to maintain a stock appearance. So far, I have dog dish hubcaps, a flat hood, and 37-year-old paint... a cowl-induction would destroy the stealth... LOL!
I honestly think you could accomplish the same thing you have mentioned by just installing a cowl hood and it would look clean and un modified all the while.
Uh.... a cowl-induction hood on a 4-door sedan... on the street....
I don't theenk so... :)
I applaud you for considering the modification and taking in account all the dynamics that would change with your idea but I personally think its a little over the top and unnecessary.
It probably is a waste of time, but I'm retired; what else have I got to do???? LOL!
Either way you decide to go, I wish you luck on the car ....I just figured I would throw in my 2 cents on the subject.
Good luck![/quote]
Thanks!!! I'll take it!!!:cheers:
