Hi guys,
Just responding to the question of "Ram Air", as it was discussed in the forum. Back in the day, I was protested for this item in ITB. I then referred to the GCR Technical Glossary, where "Ram Air" is defined (fancy that). In 2011, the definition was: "A type of induction system in which the incoming air is obtained from an extension into the airstream outside the bodywork." Bold is mine.
No one has mentioned a reference to the glossary, so I thought I'd bring it up. If this definition still exists, then the discussion could take another turn?
Good racing,

No real impact I think Bill.
THe issue here is what is "inside the engine compartment" since our rules allow the pickup of air there, or in the stock location.
To me, the radiator has to be the forward definition of the engine compartment. Otherwise, you could use the void between the grill and the radiator on pretty much any car to make an effective and never intended cold air intake.
Based on that, he Jackson intake is not legal as it extends past the rear of the radiator. Cut it off there and probably legal.

I agree with you, with the following:
This is supported philosophically, in that the regs do not allow you to make a shorty radiator and leave a hole next to it for air intake. It would be nice, howver, for that to be explicitly clarified in the regs (easy to supplement the "engine compartment" definition within the ITCS.)
I agree that the intake portion of it should be behind the plane of the radiator. However, there is no restriction to the mounting portion of it needing to be behind that, as long as air is not taken in from there.Based on that, he Jackson intake is not legal as it extends past the rear of the radiator. Cut it off there and probably legal.

I miss that car.

EDIT - Whoops. Thats a 4000Q but the radiator layout is the same; ditto for the ITB Coupe.

I dislike the radiator being considered a standard part of the outline of the engine compartments due to mid engined cars and oddballs like the 5cyl audis, not to mention 1/2 width radiators found on many hondas and a few other cars.
in the case of the miata - yeah, a fine, common sensical boundary, but I think we should be clear with ourselves that it is not a valid definition in MANY cases.
This is a pretty easy "know it when you see it" thing though. Something like "within the confines of the engine compartment, which is typically bounded by the radiator (front), hood (top), inner fenders (sides) and subframe or other engine mounting points (lower)" -- something like that.
