I believe the only reason for the heated TB is to prevent
icing. It's not about heating the air, that's just a side
effect. The "expansion valve" that the TB (or carb) is,
can take (say) 35F fog and make icicles of it, no prob,
if you're pulling a respectable level of vacuum at cruise.
I found this out the hard way once on the 404 in Canada,
heading home for Christmas break. Car got slower and
slower, quit dead, finally found a whole mess of ice in
the carb. Chrome air cleaner minus Thermac FTL. Heh.
Back to the subject, I estimate the runner cross-section
at about 2 in2 and surface area of about 24 in2. Close
enough given all the theory vs practice sniping I expect.
I'd leave the plenum out of it as big as it is.

but, we are currently doing calculations.

But what's wrong with driving a Camaro in the winter? 
Never driven one so I wouldn't know.

You CAN'T drive a Camaro in the winter. Not around here. Once it snowed on me, late fall, I had the car out... and the steamroller tires wouldn't even move the car from a stop, on level ground, at all... It just sits and spins, you need narrow tires and a lot of weight to grip in snow and ice. Never seen one driven in winter, it would be ALL OVER the place... I do know one guy who got narrow winter tires and rims, but don't know how he made out... I wasn't driving in winter, or there was no snow on the ground anyways, it was just cold out when I took that pic, the car only frosted when it got in the warm moist air in the garage... A lot of people say you're a ***** for NOT driving a car like that in the winter. It's not about being a *****, it's just stupid. Like taking a Ferrari on the Moab trail...
