yo,..

may I ask for sole distributor rights for Indonesia seriously,... it looks really nice,.. can you make any kind of body?! I'd really love to have my modified 1991 Galant GTi scaled down to 1/10

here it is: http://www.autoshow.permaisuri.com/C...20030921162114

i would like to know the progress. i.e ROAR clearance etc etc.

when is it gonna be out in the market?

cant wait to hold it and do some masking and painting.


by the way...

i have read in one website.

it says, too much downforce is no good....it will create drag thus reducing speed.
you need a balance of aerodynamic and downforce.
so.... your body is a balance body with good aerodynamic and good downforce?

and off topic about your body...
how does this downforce and aerodynamic give effect to the stratus and mazda and alfa bodies?

The hood scoop idea is nice but not legal in Roar Efra or Ifmar unfortunately.

mop_iko

can explain why?

at least HELLION and others (who wants to design bodies next time) can know the rules... and maybe can counter propose to ROAR to make a better bodies.

can someone provide LINK TO ROAR REGULATION regarding body design?

HELLION

1st Downforce: If you look at a side view of a airplane wing you will notice the top of the wing is rounded and the bottem side is straight ! As the wing cuts threw the air the air on the bottem side is traveling at a faster rate then the top wich provides lift. Downforce is the same thing only upsidedown And yes too much downforce can slow the car down but I havent seen to many bodies out there that would have a problem with this do to It would only slow the car down at high speeds on the long straights but not enough to be concerned with and it can really aid you in the turns. That said if your car is set up right then you want the downforce distributed evenley I.E. Too much rear wing may cause understeer and to much front spoiler could cause oversteer but it's rare. Heres a extreme example of too much rear downforce lol

HELLION

ROAR won't let you put a hood scoop on your car however I'm going to send a few of my bodies to ROAR and see if they will except them and I think they will! Not only do they look cool but they help a lot. ROAR rules are made to try and keep the competition at a even pace and the bodies I build with hood scoops won't make the car faster but will aid in cooling them down and I will be more then willing to work with them. I do build outlaw bodies but when I get my web site up again they will clearley be labeld OUTLAW or ROAR legal

Hellion, right idea, wrong explanation...the air going over the curved top of the wing is going faster than the air slowly going over the flat bottom, thereby causing lift.

Here's your link to ROAR

Know what? I'd say finish it ... I like it!

Sow&Steady

I like these too. Is it posible to mould functional scoops? I mean mould it to direct the air flow right at the lower part of the engine heatsink?

Sow&Steady

Oops! That's right. Bodies have to conform to certain real life touring cars right?

KevinS

That and they have some rules about the position of the engine cooling hole. It has to be in the windshield. Other holes have rules about size and position too, so you can't just make one in the hood. Unless you can convince them it's for refueling.

HELLION

Red the explanation I gave on lift Is a very basic one that has been used for years at universities. There are two trains of thought here. 1st. is Newtonians theory and second is Beroullis theory! New theorys are starting to show that wing lift is caused by wing action. That said I am right about the air traveling faster under the wing. It's a straight edge (nothing to disrupt flow) However the top is infact curved and the air has a longer distance to travel . God do I sound like a nerd or what?

HELLION

My goal is to make the hood scoops replace cutting holes in the windshield. I'm having really good success so far and they do a better job getting air to the engine then a hole because I can divert the air to a certain point but I still have a little ways to go as far as working with ROAR but I decided to go ahead and release them in late June . You can still cut the hole in the windsheild and not in the scoops if you want they look great if you just paint the holes in the scoops flat black. I can't imagine ROAR having a problem with this but you should first check with them. I will be sending them some bodies to check over this summer but I really think they will work with me on this.

Julius

Your story is not correct. If you try to explain the bernoullian theory here...
The air molecules start at the front edge of the wing at the same time. but the air traveling around the curved part of the wing needs to travel a longer distance in the same time the air on the straight side reaches the rear of the wing.

The acceleration over the curved part of the wing creates a lower pressure area ant this means the force on both sides of the wing is no longer equal resulting in lift/downforce.

It has nothing to do with there not being anything to disrupt flow.

Julius

You can make all the hood scoops you want. Just as long as you don't cut a hole in them. The scoop is okay, the hole is the problem.
