I asked this question a few days ago on the NASA sight and didn't get any info, so I'm going to try here also


I would really like to install some driver cooling air ducts in my car. However the rules state (H2) that all body panels must remain OEM. Thus I can't cut any holes. They also state that I can't use lexan for any of the windows, even the little triangle rear side ones. Most cars use these little windows to install driver cooling ducts and this is illegal in HC as far as I can tell. What is the best way to get air ducts to the driver and still be legal for HC?

 

From the Honda Challenge Rule Book:

7.11.L:

Ducting may be installed to provide fresh air to the driver’s compartment. Ducts may be installed in
the driver or passenger window area. A “fresh air system” which supplies air to the driver only is also
permitted.

7.11.M:
Driver cooling (such as cool suit) systems may be used.

 

I read "7:11 L" as permitting a duct mounted securely in a small piece of lexan near the side view mirror area of the driver or passenger window as acceptable. That's what I did.

As a quick fix, you can lay an air duct hose facing forward out of the driver's window and cable tie it in place.

 

A Texas H3 car here uses a lexal duct installed in the upper rear corner of the driver's window going to a cool suit type setup. It works fine, and is perfectly legal. Not the prettiest way to do it, but it's functional.

 

You also have to look at the track you will visit and factor that in. Being that you are on the east coast, you probably wont run into the same problem we have here on the west coast. You have nice pretty tracks, where as we have lots of dirt!

I have wanted to install something for cooling as well, but it just does not make sense for me. We race at Willow, Buttonwillow, and even at Infineon and Laguna you will get a face full of dirt if someone puts 2 wheels off in front of you. That is the reason I have not installed some sort of cooling air yet?

 

"ENDLESS 9" had this back in July 04 at Willow Springs.

 

They make them with sweet chrome k&n filters on them you know.

 

you could try something like this

the picture that outrun has, also works. Only problem we have had with it is the driver said that stuff was flying and hitting his helmet
