^^ Why, did he save you all from the big bad Triple T?
That was pretty funny though |
HAHAH damn relax
|
r u retared TTT, I did mention VENTED
|
You just fucked up.

You can look at the hood vents on these 3-rotor RX-7s to see what you will need. ;)

It's easy to put the holes in to make it vented... I guess TTT asumes we got some creativty in us... Some the guys on here call themselves car builders, but only wanna assemble finished stuff.

really wanted the hood that RX-Heaven had on his widebody but he said that they dont make it any more
|
ebay search baha. d-max hood! drop down.
|
i think that there's a b-magic that's like the stock hood but with a wider opening if you're wanting the stock look

Riz. I assume nothing, I know how to spell assume. Most of this stuff either isn't as hard as I think it is or I'm just better than I think I am. IE: I've gotten so many PM's for people wanting me to make them my strut tower bar, my door panels, my fucking VMIC setup.... :icon_no2: I don't even want to post pics of the 3 gauge pod I made today until I know I want to build a dozen more and have a GB. Regardless though, I agree. Most of these people call themselves builders and all they can do is graft LED lights where they factory incandecent bulbs used to be... WOW!!!!!!!!!!! If Atihun won't build it than I'm taking a Jig saw to my AL hood and building the thing myself. I figure some AL round stock to make the leading/trailing edge (however you look at it) vent, some sheet AL to duct it to the intercooler, TIG everything together and then go to town with filler and Glaze. Maybe a day or two's worth or work before it's ready for paint. That is by FAR the best looking vented hood I have ever seen on an FC. That one that El Nene 7 has is a close second, can't remember the name. I have it saved somewhere. Any little whiny useless bitches want me to find it for them too?

No, but it looks like you need to use thier front bumper with that hood as the recesses for the lights look longer than on a stock hood.
Reasonably, sure it is a direct replacement, no modification needed http://www.tamondesign.com/gallery/g.../photo/g17.jpg |

If you don't buy an obnoxious $3,000 CF hood for your car, then you can pretty much forget about running anything but the stock 13B engine. Everybody knows that while drift cars, show cars, and other ricers may have no hood vents, real race cars like Mandeville's winning 3-rotor car need hood vents in order to function. |

Sorry should have explained myself, the hood is Tamon design (even has their URL tagged to the pic). The guy behind Tamon is the ex chief of design and development of aero parts for RE-Amemiya, so a lot of his stuff is confused for Amemiya.

Seeing as how you have more aero knowledge than most on this forum combined, am I wrong in thinking that a hood like the atihun hood, would allow a small vacuum to form at speeds aiding in pulling air through an intercooler core if it was ducted to it? |
EA, How do you think he is supposed to get his baller status up and bring home the hunnys with a stock non vented hood? He will get laughed off the track.

When the car is moving, ram air will force its way through the ducting system. The hood suction and natural convection are just an added plus that will not make a huge difference in my opinion.

Yes, plus the heat would tend to rise through the top of the hood due to natural convection, even when the car is not in motion. The outlets are supposed to be ducted from the heat exchanger rather than simple holes in the hood, and they should have a combined area of at least 115% of the inlet area which itself should be roughly 25% the area of the heat exchanger core. If you want to get fancy, you could add adjustable outlet louvers to optimize the flow for given speeds, but I think that is overly elaborate for a sports car's intercooler. When the car is moving, ram air will force its way through the ducting system. The hood suction and natural convection are just an added plus that will not make a huge difference in my opinion. I agree that the moving louvers is a little over the top for this pj even though just about everything else has been over the top anyway. This gem of a thread - https://www.rx7club.com/showthread.p...ighlight=d-max I will never forget had, litterally, what looked like a hurricane symbol in the corner where the windshield met the hood that they claimed would pull air out from the engine bay. Total marketing bullshit but I'm sure alot of people bought it. Subsequently D-max took it down, shame too, I always got a kick out of it.

|
Does this guy even need a vented hood? Seriously, they are functional on about 5% of cars who actually put them on. Just because he has a 20B doesn't mean he needs the hood.
And yah, that amemiya hood looks like it does need the matching bumper to be used. |
you guys crack me up...

They will be ducted though and fuctional. The ducting is a double edged sword I think though. While it allows the i-cooler to work better, it does nothing for venting the radiant heat.

The orginal idea was to just cut into that and leave it relatively flat. Would a leading edge be beneficial there as well to create a small amount of vacuum or am I too close to the windshield at that point where it would force air into the bay at speeds or do really nothing ayway?

Even if it's not ducted to the coolers, it should help reduce the pressure in the engine bay and vent some air out (provided it's designed properly of course). This will be beneficial to cooling all by itself. Sure ducting is better, but it's not 100% necessary for it to help.

:facepalm2: I'm seriously going to put a request into the mods for you.
So you're saying A) A vented hood only belongs on a race car B) A little rain water is catosrophic if it lands on an intercooler C) According to AE the vent needs to be roughy 29% of the size of the core, yeah, that requires a huge amount, say half the fucking hood to be cut out right there D) We all know you envy me. It's flattering but please, if I catch you stalking me, I will stab you in the eye. E) A dedicated race car owner and track junkie went to GREAT lengths to get this hood, I'm sure it's junk and completely useless. |

http://www.ch601.org/resources/cooling_systems2.htm Aerodynamics speculation is rather tricky, but I think that you would want a lip or some type of outlet duct in order to keep ram air from shooting down the hole. I don't think it would be too close to the windshield. I'll prob take a few pics of the mocked up vents and play around with them some. The main vent for the intercooler is going to be a pretty damn close replication of the atihun hood though. [quote=Evil Aviator;8797676]I'm not a professional because I have nothing to sell you, lol. Seriously though, brake ducting is outside of my realm, but I can look at it anyway. :hahaha: The brake ducts aren't so much how they work but where they are located that is the cause for concern.

No, he needs a GOOD radiator (not some crappy Fluidyne drop-in or corroded junk yard radiator) with good ducting. One thing to keep in mind with a 20B is that the engine is much longer and may interfere with vents near the center of the hood. Also, a stock 20B-REW engine will not clear a stock FC hood, so some type of hood bulge (or gutted TII hood) is required unless the engine or its mounting position (including steering rack) is modified.
Most of them are just for looks, but you could still make the outlets functional by spending some time on some custom duct work.

Someone has a great sig, something along the lines of one test result is worth more than a thousand expert opinions. I think it's RotaryGod actually. |

TTT, that pic is a week old. It was taken in the Blue Ridge area.
Are you actively looking for an atihun hood? Reese |
i just paid a 1.32 in zebulon
|
Damn CT gas prices.
I'm looking but not exactely actively looking. If I found a great deal I would probably snatch it up but there are other priorities that need to be addressed first. |

While it's not an FC, they did go through that sort of development process and many people find that it helps with cooling on track. It's difficult to cool a turbo Miata on track with the small rad intake on the car, so an improvement in cooling will be very noticable. |

That right there is some damn good reading. 3 things learned from that 1) While testing would be beneficial, I am in need of a vent for the intercooler, not just the engine bay so my vent placement is more limited than thiers https://www.flyinmiata.com/projects/...s/OTC_aero.jpg 2) Looks like I'll be trying out a shitton of adhesives. I don't think I'll be welding on my perfect AL hood anymore

Yeah that one. I dig that one too but not as much as the atihun. I would rather see one vent that goes all the way across than a bunch lining the hood. It does retain some curves to it which I like, unlike the one below.
I really like the looks of this hood as well. It looks aggressive but not ricey. As far as the number of vents is concerned, a bunch of smaller vents like that could actually be productive as the velocity in a smaller duct is generally higher. Then again it depends on how much air is actually flowing in. I not about to try and figure out the flow characteristics under the hood of an fc. I would imagine vent placement is one of the most important factors and if I remember right the middle of a smooth hood is a low pressure zone so I would imagine that would be the best spot. Then again, is a venting really all that necessary? I know I'm not concerned. |

Here is a pic of my new hood. I just got it Friday. It is sort of like a KS knockoff, but I don't think the center scoop would look good reversed what so ever on this one. I really wanted the panspeed hood, but I needed the vent(s) farther back to clear my liquid to air intercooler. You probably should consider the same fact, being that the longer 20b block may have similar clearance issues.
Sorry for quality, my only camera is the cellular variety https://www.rx7club.com/attachment.p...6&d=1229296080 Obviously you see the 3 vents on top. Also notice the back of the hood curls up by the cowl slightly, where another vent runs the whole width of the hood. This is what I had to clear towards the front of the engine bay https://www.rx7club.com/attachment.p...7&d=1229296151 It may be a little more aggressive of a hood than I had been looking for, but it will be super-functional for my setup, plus I scored it brand new for $180 :icon_tup: |
