aight guys im in the middle of making a hood for a guy in town. If anyone remembers I made one for a v-mount setup for a guy in New York. His turned out ok but got some damage during shipping. I used some different reinforcement on his hood and since then I have cleaned it up and got it down perfectly in the new one i have made so its even lighter and stronger as well as cleaner. Anyhow i am working on a new vent setup for this local guy and i wanted to get some opinions and share some thoughts. I made the vents more forward then my single vent in the middle so it sits atop the fan and the vents themselves arent quite as large and much easier to block off in the Portland rain. I also decided to add some other vents in the corner RE style. I am aware that there is negative air pressure by the windsheild but as the air wraps around i am sure that there has to be some air sucked back from the corner vents, so i wanted some input, as well as considering the main vents are on top and not behind the stock fan......here is a photoshpped pic, looks nasty but gets the idea across. I have the thing alomst finished but I'm not there to take pics yet, the only thing I have left to do are to finish up the sides of the vents....anyhow, gimme some feedback

 

not my cup of tea but it could look nice!

 

i prefer liptons

 

actually i like it alot if your willing to sell me one CHEAP! cause im a broke person lol i live in miami fl 33183 give me a price i like the pic of that one if not send me a pic of the other one your desiging pm me
Thanks

lemme give this to matt and let him paint it and then ill make a mold and sell them cheap....ill sell a few for 385.....which in comparison to to some other hoods out there for fc's are pretty cheap. fc3s.org sells them for alot more and they sell carbon fiber, BUT they have a full replica underside which is much cleaner and they have the overhead to vacuum mold these thigns and the get them looking damned good, so with them you get what you are paying for. FC owners for the most part dont have alot of money to blow so when I get this to Matt or have it painted myself one or the other ill make a mold and shell them out. But guys i want to know what you think of the rear vents the funtionality of them.

 

you should design some kind of schoop that works like the TII hood make a mold like that and could you send me some pics of how you do these molds ive always wanted to know....
Thanks

i like the t2 hood but there is some debate about how functional the scoop actually is due to the pressure zones. And the reason i designed it this way was because i wanted to stay away from any raised surface this time. It became a really big pain in the *** on the last hood i made because you have to get both sides exactly perfect and it isnt as easy as it looks, plus the guy who had ordered it had paid ahead of time and I was running out of time so it was becoming difficult to get the quality i wanted out of it. Anyhow, in making this hood i just made a mold of my stock hood, made a hood from that mold and cut and push basically.

 

no thanks, i'm partial to uncle ben's

 

I like it. i'll buy one but not till the summer time or untill i get a job that pays better. I guess if i dont spend all of my tax returns then i'll get it. lol

sounds good....anyone with ideas on the scoops....like technical opinions

 

a pic

 

another pic

 

question: with those clear a strut tower brace?

 

yup...and looks like the local guy wants to sell his s5 so he might not be buying this one so it might be up for grabs....first 400 will take it when im done if he doesnt want it

 

looks good and functional. id buy one if i diddint already have a carbon fiber hood.

 

Looks like an 03' Cobra hood

id have to say its one of the nicer vented hoods ive seen. even looks earodynamical y functional. its just that my car needs 385 put into a lot of other stuff than the hood

 

my concern would be where the hood vents drop. The last thing you want is to have the vents dropping water onto the belts as its parked. If it gets cold enough, then your belts freeze.

 

aside from cold temps is it okay to have rain rain in on your front cover,radiator,etc?

 

the vents are actually placed differently and much more foward than before. the last design I made actually had the vents over the gap between the fan and the belts. These front vents are on top of the fan, thats why they are somewhat curved out and bigger on the outside. So if it does get rain its all going to be dripping around the plastic shroud. Secondly these vents are symetrically small enough to easily make block off plates to where if it is going to be parked and for some reason rain is a concern you can just block off the vents.

 

Nice. If I went front mount I would get a hood like this.

The one thing I would change is the center part. Maybe have a different angle in it instead of a striaght line.

Maybe make a V out of it but a thick one to retain strength.

 

You really need a raised lip on the leading edge to make a reverse cowl hood as effective as it should be. I think it makes it look better also, and your prototype hood is no exception in both cases. Looks great (even better if it had a raised lip), keep up the good work.

 

I dont like it, it is too busy....

 

the last one i made had a raised lip, i didnt like it, plus i wanted something a lil more sleek

 

another angle....ill post more pics when i get it painted. the inner part of the vent is half an inch down and the outer is 1.5

 

The hood looks good I wish I had pics of my hood to post. I have an inverted vent(s) I molded to my hood. The front of my motor has gotten wet through the holes on it before, not soaked but wet.

 

Without the lip on the edge you won't form a lower pressure area at the openings to suck air out. The lip has a huge impact on how effective the scoops will be. Of course if this is just for looks...

 

huh, mine has a lip on it but only by coincidence!

 

i beg to differ...the positive pressure created that sucks the air out isnt due to the lip...it aids it but not entirely due to it by any means. the positive airflow is created by the front of the car hitting the air and the air moving upward and back. if you want i can show you the airflow chart

 

I've seen testing that proves it makes a significant difference. That's why they practically all have them.

 

yeah I was going to cut the NA hood from my vert like this at one point. Never got around to doing it. Good work though.

 

your water also drains backwards down there, thats probably why

 

7his is teh diagram!!!one!!1!1

 

sorry to hijack my own thread but it is very late and i am very tired btu i felt like throwing in some delerious stupid humor

 

I really like the hood, except for the two rear vents. I was looking for a hood with similiar vents to the two large ones you put on the front. I just think that the 2 rear ones give it a little too much. What would you charge, after delivery to make me something SIMILIAR to the one shown but witout the rear vents??

 

What I would really like to see, is a vent (or small vents) above the turbo/dp location.

That is where the most heat is generated.

Unless of course, putting the vents there, won't really do anything based on the whole air pressure differential stuff that I don't know about

 

I don't understand how vents facing that way work... the movement of the car wouldn't allow air in through the gap in the bonnet... isn't that the purpose of the bonnet scoop? To peel air off and feed it to the intake? Does this work as an exit for the air coming up through the front?

 

if you look at the airflow chart there is a low pressure are over the vents and actually the airflows outwards as the air flows back over the hood because of this, and a front facing scoop at this point wouldnt do a whole hell of a lot. T2 scoops arent as functional as you think. As far as making another one id do it for 400 which is damn cheap, but right now i have alot going on and i have this prototype pretty much done except for the finishing touches and i need the money back out of it for my honeymoon in paris at the end of the month so i want to get rid of it and Ill make another when i get back, so 385 without the shipping takes this one.

 

the hood looks very nice. Can't wait to see the finished product. good luck finishing it, I hope it turns out as planned.

 

i wanna see it finsihed to only problem is that I am on the broke boat now paying airfare and all and my plan was to make this and mold it and sell them, but i wanna get my money back out of it, so ill sell this one and make more at some other time. The only thing left to do is to clean up the underside with some wetsand and some icing to hide the mat and clean up the vents with some ice and sand. Ice is expensive ($20, yes im really that broke) so ill finish it if someone wants it.

 

I think that hood looks really good. Considering that rotaries generate so much heat, you'd think there would be more "vented hood" designs...but there aren't. Of the few out there i'd have to say i like your design the best.

BTW, on that aerodynamic flow profile pic, do those arrows represent the magnitude of the pressure or what?

 

thanx for the props. i feel satisfied now that i made something that i think looks good and is really really lightweight. You are correct on the airflow chart, except for the second one where i put the AOL highspeed, that really has an effect, but its only for the internet

 

I too, like it, except for the small rear vents.

 

ah yer back, so consensus is that i shouldnt make the rear vents next time

 

i just think that the rear vents give a little too much... If you would take out the rear vents, i would buy the hood. Im getting my car painted in a month and a half and I could really use a custom hood........ Let me know

 

The hood looks great ive always liked that style but they dont exist for the FC unless a person like you makes them which is awesome, i would definantly concider buying one

 

i would definitely consider making a mold and selling copies but right now i need the cash for other things. So crickifur check ur PM's. Anyhow my main concern is getting rid of the prototype so i can recoup some cash and when i get back from paris im making a full on bodykit for the car when i have some cash flow. So no more rear vents. And RXhaven7 you are right and thats why i started making this stuff because its non existant, and i wanted to sell it cheap cuz other wise u have to pay over 1000 bux for this stuff. So keep an eye out in the future for me to offer stuff as inexpensively as possible, as it is a hobby and not a business.

 

rear vents are gone

 

WTf why am i twentyB??

 

you got pwn3d by the server
