& Clack Talk Cars
by Tom and Ray MagliozziDear Tom and Ray:
In the 1940s and early
50s, we had a big old buffalo robe, and I
remember my "old man" putting this
blanket on the hood of the car or on the engine
to keep it warm in the winter. Im wondering
now if that had any effect in cold temperatures
as far as keeping the engine warm for cold
Minnesota morning starts. - Ken
RAY: Well, lets start by
discussing blanket technology, Ken. A blanket
works by slowing heat loss. So, if you wrap
yourself in a blanket at dinnertime and then sit
outside in zero-degree weather, youll lose
less heat than you would have without the
blanket.
TOM: But is the same true for a
car? Well, the big difference between you and a
car engine is that you keep generating heat all
night. Thats a function of being alive.
RAY: So the question is, Does a
blanket slow heat loss enough to keep some heat
in the engine 12 hours later? Probably not.
TOM: In cold weather, an engine
normally loses most of its heat in about three
hours. The only exception is the oil, which can
take as much as eight hours to reach complete
equilibrium with the outside air..
RAY: Can a blanket extend the
time it takes for oil to get cold by an
additional four to six hours? I dont think
its likely. But if the car were driven at
11 p.m. and then started at 6 a.m. the blanket
might make a difference.
TOM: But while a blanket might
have been the only option for your old man, there
are better alternatives these days. There are
block heaters that you can plug into an
electrical outlet. They actually generate heat.
And then theres the greatest advance ever
in cold-weather car-starting: The heated garage.
RAY: And if you build one, Ken,
put the horse in there too. Hell appreciate
that a lot more than a stinkin blanket.

Dont
Blame Goodyear for Charlotte Fiasco
Q: Greg, I thought
the Charlotte 500 was going to end up being like
the Formula 1 race at Indy when most of the cars
(all but six) refused to start the event due to
tire problems. The drivers in NASCAR did race,
but whats wrong with Goodyear? Alan,
e-mail from Texas
A: Alan, I agree
that the 500-mile Lowes Speedway event at
Charlotte came close to being either postponed or
shortened in length due to tire problems. But the
problems arose after the speedway had been
scraped for a better overall show, and no one
really knew about it but the Charlotte staff, led
by promoter H.A. "Humpy" Wheeler.
Wheeler basically
had the Charlotte racing surface scraped without
knowledge of either NASCAR or the Goodyear Tire
Company. The result was an extremely fast track,
but also one that ate the tires.
In Goodyears
defense, a company cannot develop a tire that
will withstand a scraped surface unless it first
tests and then develops the proper rubber for the
re-configured track. Goodyear was defenseless.
So, lets just chalk this one up to H.A.
"Humpy" Wheeler. Everyone makes a wrong
call now and then, so as for me, Humpy is still
the best when it comes to putting on a race.
