Re: Re: overheating

You can also make some kind of "ducting" to block the sides of the radiator to force air through. I have this, too. Originally made out of cardboard and racer's tape, it's now a little more permanent with aluminum sheet.

Pat, that is definitely illegal in IT.

Re: Re: Re: Re: overheating

How so? It's part of the air dam and "openings are permitted for the purposes of ducting air to the brakes, cooler and radiator" in regards to the air dam, and all the ducting is attached to the front bumper. It does not "cover" the normal grill openings on the front of the car. No support or reinforcement extends "aft of the forward most part of the front fender wheel opening." Unless there's some specific wording in the rule book that I can't find, I see it as creative rules interpretation.

That's very creative IMHO.

From the ITCS:
"Openings are permitted for the purposes of ducting air to the brakes,cooler,and radiator."

and

"Any radiator may be used,provided it is mounted in the
original location,maintains the same plane as the original
core and requires no body or structure modifications to install."

No where does it allow for sealing off the flow of air to the radiator. It only allows for an opening in the airdam to flow air to the radiator. The stuff you're talking about is not connected to the airdam at all. But, I could be wrong. A lot of folks didn't believe spherical bearings where legal until I wrote to Sven Pruett. I would just make certain it's easily removed should someone decide to protest (IIRC your region has a lot of folks who like to protest).

Re: Re: overheating

How would you "duct" the air to the radiator after making an opening for said ducting? If you can duct air from openings you have made, why can't you run ducting from existing openings?

I would read that to say you can create a duct in your airdam. But it says nothing about in the coachwork. A similar example would be brakes. You can have a duct in your airdam for brakes, and elsewhere in the ITCS it specifically mentions running hoses to the brakes. There is nothing elsewhere in the ITCS about creating a duct or boxing in the radiator in the coachwork.

That is how I read it.

I know .... it's a gray area. But I have the slowest car in ITS in the MARRS series, so I'm not really worried about anybody complaining about my car. The aluminum is easy to remove anyway.

Yeah, I know. I'm not trying to slap your hand. You can run illegal pieces if you like. Just trying to warn/help you. Also, trying to do the same for others running IT. But as for running illegal parts and set-ups, I have 2 or 3 minor things I'll be doing that won't be legal. They are non-performance items and mostly for convenience, but illegal none the less. None of them will be terribly difficult to bring into compliance though if someone protests.

Oh my front splitter worked wonders this weekend in keeping water temps down. It never got above 200 the whole weekend. Outside temps were in the low '70s, and I've run in similar conditions before and watched the temperature gauge climb up to 220 or so.

Great info Pat. The guys running turbo road cars need to know about this.
