Fiberglass hood mods... crazy?

]I guess I am not quite sure what it is that your looking for here?.[/I]

I am looking to get the trapped air that comes into the engine bay through the radiator out of the engine compartment by giving it an escape route over and above (no pun intended) what exists, now (which is, out the bottom.)

Adding a belly pan would actually trap that air inside the engine compartment to a larger degree, giving it nowhere to go, and increasing the pressure inside the engine compartment, it would seem to me.

You came to the thread asking questions and looking for answers and you brought an idea to the table and it seems that everyone that has given you ideas or given you an opinion on your idea......you have turned them down and argued on their points.


I have examined what I thought were the plusses and minuses of each and every suggestion; that's what a discussion is for. The fact that I didn't see any alternative to what I am attempting with my "flaps" in the back of the hood is just my opinion... and is surely not proof that mine is the best idea; just my opinion, and you know what they say about opinions. I tried to explain why I thought the "flaps" would work better, in each case.

Beyond that, I'm not sure what else I could have done. I', no doubt, should have posted a picture of the engine to illustrate that it's supercharged and that it doesn't have a conventional air intake location. My bad...:angry7:

I am not being rude or anything here,don't get me wrong....just an observation.

I never take constructive criticism as "rudeness." I appreciate the input, and the honest effort you've made to offer valid suggestions. That's not rude at all; just an attempt to be helpful, and that's why I asked.


If you're looking to keep the car looking "bone stock" as you say......I guess I don't get what the difference is rather you have a cowl hood or you cut big ugly holes in the hood and put hinges on them...either way it's not going to look stock, and one of the 2 ways will not look good.

A cowl hood has a reverse-facing scoop that is usually over three-to for-inches tall... sometimes more. That is VERY visible from the next lane. The only thing sticking up on the "flaps" deal (above the original contour of the hood) will be the piano hinge, which is less than a quarter of an inch tall, and wil be painted the same color as the hood; not very visible at all, unless you're right on top of it... The slits will be very narrow and will be pretty much invisible unless you're looking down on them. Of course, when they open up, at speed, they will be VERY visible, but that's just for a few seconds, and after the race is under way.

Sorry, I am just trying to be honest here...I don't see the point in cutting a perfectly good hood and even more so when your results from doing so will most likely not be that great.

Well, as they say; you can't make an omlette without breaking a few eggs... LOL! There's no way for me to learn about this deal without doing it. For sure, it won't HURT anything. The cut hood will still keep 95-percent of the rain out (at least) and will continue to function normally, in all respects. If it doesn't help (and, it may not), I'll go to plan B and probably build that belly pan, but keep the flaps as a way to evacuate the air in the engine compartment that came through the radiator; it has to go somewhere, and the bellypan will preclude it going out the bottom, unless I put louvers in it, which is not really a bad idea, now that I think about it...

I DO appreciate all the time you've taken to help me wrestle with this problem.

Many heads are always better than one... :read2:

I think out of anything, i would make a belly pan for the car.

That would drop any engine bay pressure significantly and maintain the stock look of the car.

That'll be plan B... with louvers, pronanly, to keep from trapping the air that omes in through the radiator...

And you could also cut a trap door in the belly pan for easy access to changing oil filter and what not ....you could even use piano hinges on the trap door if you like since it sounds like you really just want to put piano hinges on your car lol!!!!! ...J/K.

I personally would put a belly pan on the car and I would run ducting under the car and plum in into your air inlet for forced air....I did not realise your induction set up until seeing the pictures and I think you could REALLY benifit from the forced air ducting instead of moving in still warm engine bay air.

What you say about carburetor air intake location is 100-percent true, and will happen. I built this thing in a hurry, and didn't give proper thought to the air intake for the blower.

Just some thoughts and again...I am not picking on you or being rude here, just my .02 cents on the hole thing.


It never entered my mind that you were being anything but helpful...
No problemo!!! :happy7:
