Whew, we could talk all week about period cold-air systems, especially those
of us who fancied American musclecars growing up. Hell, I owned a '70 W-31
Olds in high school, surely among the more wild forced air induction systems
(specifically the W-25 Cold Air Option on the Olds). I like how the late
'60's GTO's with their Ram Air IV options had a lever inside to close off
its snorkels in case of foul weather.
What were other people's favorite systems? Did you favor the brute force of
a wide late '60's Hemi Charger's scoop, or the zany '69 Rambler Scrambler,
complete with decals telling the air which way to go, or the more subtle
base-of-the-windshield variants as on the Series 1 ZL-1 Camaros...?
I'd always wondered what happens if the air pressure above the float level
is different than the slightly pressured air from the ram air box.
Obviously Alfa Romeo went through great pains to assure equal pressure, as
evidenced on the lovely air box on my '67 GTV, and especially when looking
at the TZ-1's air box.
(wishing for a TZ-1 of my own)
