Would you install this hood?

1. If they sold this hood for Fb's would you install it?

2. Do you guys think its possible to just make one with some fiberglass.

I happen to like the hood, plus it's funtional. I know this guy who's really good whith fiberglass, and thoughy maybe he can coypythe design.

Just anted to get your opinions!

Thanks

Luis

Faster moving air over the top of the vent makes a vacuum inside the engine bay and draws hot air out as I understand it.

You use some kinda-fine mesh screen mounted on the underside of the vent's opening, to sort-of keep ****
out, but not liquid's (water) will get right in. That is a big-*** vent, in that hood.One would think, that a style,any style will look ok on a 1st gen, then you see, or it 'comes' to you, that allthough the 1st gens hood, fender,profile is very simple, only a couple of,vents/scoop really look right. IMO

If you look closely, you can see the fan. In the angle that it sits, im sure it blows all that heat right out of the engine bay. Since I'm instaling a FMIC, i have no need for a "ramair" hood.

Since they dont sell hoods for our cars here in the US or canada, I guess were going to have to fabricate our own.

BTW: I don't think it'll be snowing any time where I live

I'm looking to fab something like that up in the near future (the next 6 months or so). As well as the full custom wide body kit.

i like the vent idea.... great way to get the hot air out and if you do it right infront of the motor and behind the rad then nothing gets wet man that vent is HUGE a can cat would crawl in there.

It's acctually a stock GSL-SE radiator, and I had to make mounts to hold it where it is.

Thanks for all the advertisement Carl, and I did find your buisness card, so here is a hello back to you!

No, popping the hood latch will allow the air building up at the base of the windshield to enter the engine bay. You will be inducting cool air into the engine bay (on it's own merit, good) and increasing the air pressure inside the engine bay, which is the complete opposite of a vented hood.

The purpose of a vented hood is to use the low pressure area on top of the hood to "draw" hot air out of the engine bay. Effectively reducing the air pressure in side the engine bay and sudsequintly behind the radiator...... Now at speed you have a higher pressure area in front of the radiator than behind. If you throw in the vented hood the lower pressure area behind the radiator becomes even "lower". Now the high pressure area has then need to fill that void even more moves at a faster rate, therefor more volume moves through the radiator, and voila more effective coling from the same radiator.

Thanks for listening,
Ryan

Well said. Another benefit is that the high pressure air is now exiting out the top of the hood instead of going under the car, means that it lowers the air pressure under the car, reducing lift, giving more front downforce.

At my last track day, there was a guy with an NSX with this setup and he said it produced noticeablly more front downforce, even though it wasnt completely finished and sealed up.

That hood looks really good if you guys find out who sells them and what not, that will be really cool.

The vent itself is really nothing more then just cutting
the hood 3 times, but whats more important is,,where !
one cuts 3 times...yep.. the stuff that you see 'on' the hood(outside) is just 'extra' aero-styling, oh. i'm sure that ,,that small 'lip' around the vent does effect some ,
but thats one way to make a huge hole in your hood not look so bad. I'm all about vents,, i think if done well the vent(s) look ******* killer. Thats one reason i say 'mariah' they've been there, and. Done that . the body 'kit' on that blue 3rd gen looks like a RE Armiamia ....,,.,...,.,.something,...
