I would not have thought there was much water in the Bonneville air to freeze
but a quick look at a psychrometric chart tells me I'm wrong. Summer design
condition (ASHRAE recommended values for air conditioning calculations) for
Salt Lake City is 94F dry bulb/62F wet bulb. This works out to a dew point of
37F which means there would be plenty of water to freeze when the cold surfaces
get to 32F.

In '72 I was hanging around Jack Lufkins crew and they were fighting
that problem and no boost in low gear.
They were trying a alcohol & ice mix in the 40 gal tank that fed the two
vary large intercoolers.
It worked so well that there wasn't enough heat to spool up the turbos
until after it was in second (3-spd 727) and by that time the IC's were so
iced up they wouldn't flow. Rich mixture fouled the plugs.... T.O.
The fix was simple. The driver didn't turn on the cooler pumps until
after the 1-2 shift. The result, I believe, was a new record.
As the old sayings go; be careful what you ask for, you might get it and
watch out for the law of unintended consequences.
I don't remember the numbers but lowering the charge air temp added
a bunch (100+ HP??) to the BBC. (Sports Raceing was a gas only class)
