Just to debate the definition of the Engine Bay/Compartment .
Where would the radiator be located, or described as being located, if it's not the considered the engine compartment ? I would think anywhere under the hood, and aft of the grill , would be considered as engine bay . Plus, I believe in the definition that Greg supplied, makes no reference to for or aft of the radiator being a boundary for the engine compartment.

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.

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

Agreed, these do matter for cooling. Dave, look around online, some of the Miata aftermarket places have the factory pieces availabe (gomiata I think?). I just put an NRG aluminum panel on my SU car becauase bling matters... (and it was the same price as the factory piece, and I don't have rules to live by)
