Well guys since I am not in Iraq as of yet and have a lot of down time I decided to to add a little more body customization to my car. I am adding some vent scoops to the car, I have the basic shape pounded out and the vents are far from being complete as I only have one layer of fiberglass on the left side and I have to still sand, shape, add more layers of fiber glass. and repeat still I get what I want. Proeject is on hold for a little bit since all my tools are in a storage shed 80 miles away, Thought I would be in Iraq by now. The sheet metal is the skeleton of the vents to give it a little support. From what I can tell when I made my home made wind tunnel...LOL don't ask. Its amazing what a friends 5 car garage and some HUDGE BAY style fans and a smoke machine with dyed smoke can do, we have VHS footage of the test Ill try to get it put to computer, They seem to work Really well.







Edit- They may look like crap now, But the vents are far from done. The car is going to have new front, sides and rear put on and a fresh new paint job

They are going to be functional, right?



Yes they are, When we made our makeshift Wind Tunnel the air flow was awesome, I could see the air flow trough the vents and out the back, I am going to be putting a rear diffuser on the car in hopes that the two compliment each other. I am board and just messing around with Aerodynamics right now. I was saying to my friend to bad we dont have a Wind Tunnel and he sat there a sec took a drink of his budweiser and said well lets build one.....LOL. I am sure it was nothing like flying down the interstate. But I took the car out and there was no noise from the vents what so ever




Edit-LOL Come on leet you should know me better than that, I dont do something if it dont have a purpose. Why the hell would I build side vents that do not function. This aint the F&F :p
 
Thats cool that they work well. I bet they will look slick when you get them finished.

Thank you, the vents that were/still there were done by a body shop and they flow way wrong with the shape of the car, So I decided to had some custom scopes on them that flow'd a lil better with the wheel well and and basic...Fat Ass Roundness of the car. I think the vents will look slick when they are done. I want them to almost look factory but I also want them to have that aftermarket race look to them :thumb:

I'm not very good at these aerodynamics stuff so what are they supposed to do?




Its kind of hard to explane, but ill try...The vents help redirect air flow from around the car to through it. The vents are routed in such way that the air flow exit's out toward the rear of the car hopefully creating a little more down force. The person who made the vents in the 1st place did not do much thinking about the design I guess because the way they were before they did not flow that much air. And also they just did not follow the body lines of the. So I figured I would add to the vents so that they looked a little better and had a little more functionality to them. once they are completed I have a place were I can do a Balls to the wall full out WOT test and find out if they work like they are supposed to

This makes sense. Downforce! Didn't think they were for anything else :) Anyways, very nice job! :rocks:

Well, if you're ever really bored, make a front undertray for your car as well. High speed handling is seriously improved. Going from a bumpy ass front end (underneath) to nice and smooth did wonders for the cars capability. Just be sure to bolt it down VERY well. It also helps to have a hood vent, since less air will be flowing out the engine bay from underneath the vehicle (great to reduce lift).

I've looked into designing a diffuser but the design of the rear end makes it difficult to bolt up. Ideally, the spare tire well would probably have to be cut out and replaced with a flat piece of steel.

Sorry man, I had to ask LOL!

Vents? All I can see is that piece of highway guard rail hovering over the trunk lid.




:p The wing is going bye bye, I just have to find something I really like. I am going to build a Frankenstein car. For what purpose has yet to be determined. Any ideas of a wing that would also flow with the body lines as well as the vents? I am thinking about going with the Erebuni GTR Wing not sure yet though

Yes it does, if you ever come up with some great ideas for a diffuser let me know. :thumb:
 
I always thought that the side vents were to help cool the rear brakes ...
 
Sooooo at what speed do you drive that down force will play a factor in handling? Are you road racing this beast?
I do admire your creativity and skills and not having fear of seriously f-ing up your ride.

Do me a favor when your in Iraq and kill as many as those terrorist mother F'ers as you can please.

I love road racing, I was supposed to race this year but other unseen factors came into play. I still might end up re doing them and building them so they can function to cool my rear brakes. Still not sure on the whole thing, as for ####ing my car up, well its just a car and the reason I bought the thing in the 1st place was as a learning tool to help me along. How is someone supposed to learn if they don't get up and do it. Also if I ever ####ed it up I would just take it to a body shop and say restore this please....or just go all out and rip everything out and make it all race.... About the Iraq thing well I sent my resume into Blackwater and I am going to be mailing it to Triple Canopy also, so well see. :thumb: The insurgents are chicken shits any ways, its one thing to use unconventional warfare and guerrilla type training and skills to fight a war...but how they hell are you supposed to fight when all your soldiers are dead from being suicide bombers? Or if your to chicken shit to stay and complete your mission and act like a freaking idiot shooting from the hip and not aiming at anything? Any ways I really want a carbon fiber front bumper for my beast of a car. Shit I cant find any though. I would paint it...I am just sick of fiberglass thats all
 
Thats because they believe alah will guide there bullets and kill the infadells. :p Or some really stupid shit like that. Anyway not to go off topic anymore but one of my former co-workers was killed in iraq working for blackwater (remember that chopper that went down about 2 mnths ago?). Anyway good luck and be safe.

Does your wing do the same thing?
 
Side vents have only been used for either A) brake cooling or B) engine air intake...

There is a lot more involved than just adding a vent to cool your brakes... If you notice some cars with rear vents to cool the brakes were designed with a type of rim that allows air to flow through the wheel. Same goes for slotted and drilled rotors... there are right ways and wrong ways to them... You can always get air in... but the question is can you get it out. If not then you are just defeating the whole purpose of everything.

Also you have to keep in mind that a lot of cars that have the vents in front of the rear wheel are actually intakes for the engine since most are mid engine cars such as the NSX, Porsche's, Ferarri, Lamborghini....

Ill have to get a picture of a nice clean side vent install, ill try and get it posted next week when i get home
