as u might know im in the middle of repainting my car.. anyway when i had my hood off the other day i was loooking around in my engine bay and had an idea. i dont know if anybody else has done it or not so i thought id ask and get yalls opinion. on the firewall after removing my a/c lines and stuff i noticed it is pretty clean and just bare metal. well i was thinking about cutting two good size holes in it (one on each side of the hood latch) and finishing it off with a rubber trim to make it look nice. i want to do this because it seems that the holes and the vent on the top of the metal a obove it would act like a cowl hood and let the engine breathe better. please tell me if you think this is a good idea... pic is attactched.. black resembles holes and blue shows air flow after cutting em out thanks in advance

This has been covered before. You will get water in the engine with this kind of mod.

woudl it be that hard to make i was for air to get and and to not let watever in at the same time? like soem sort of angled cover o soemthign of the sort??

cwsttu

well my car is going to always have a cover on it and i will only have the cover off of it to work on it and drag it. henceforth if it is raining i wont be working nor racing it. so is this idea ok for my specific needs ya think? sorry couldnt find it in search since this has been covered

HEy if the car will never see the elements and isnt goiung to get wet, Hell do it. I think its a great idea, but everyone is right that your stuff will get wet.
Everyone knows that cooling is critical for the rotary, and if all it is is a race car that right on tell me how it works.

Okay, here is a quick draw up of the manual operated air flapper. The springs keep it shut and the hook keeps it open.

I also have a cable operated flapper designed and a electric flapper designed.

This is by far the easiest one to make.

I suggest spending your time and energy on something that will actually make a difference

and with the aerodynamics it will force air in the engine bay not out.

gee wow thats great thinking, i didnt really give that much thought to it thanks for the info

If it's strictly drag, I'd think you'd be better to save the weight (every ounce counts) and just open the hood between runs or something. I know with my e-fan set to kick on at about 170 F, I don't have any trouble keeping the water (or the oil for that matter) well below dangerous levels.

Cool idea, but maybe not that practical.

Drill some drain holes, somehow, to let the water come out.

Wouldn't you get engine gases through your vents if you did this?

damon

yes you will get engine fumes at idle (ask me how I know)

peace
