It Ain't Over 'til It's Over
Jim Knapp, Joysticks
Some of you know
me, some of you don't. I run a seriously fast Honda that currently holds
two World Land Speed Records. I'll be 58 Monday and have been racing
on and off for over 40 years. Until last night, I was beginning to think
I had a pretty good grasp on "reality."
This story is
to warn you racers to always be the student! Our egos and faster
and faster nature are both our wonderful friend and fearsome Master.
Be mindful of the game we are all playing!
I could never
have imagined what happened in this story. I always figured I was safe
up in the front of the car, a solid steel firewall separating me
from the engine and all the mechanical and chemical problems that can
occur back there. No way any fires, explosions, or spills could come
forward against a 200+mph headwind, right?
And I knew
I was really safe when I felt the chute hit. That always meant all was
well and I could relax.
Well, Bob Herda
knew all that, too. And he's now dead. A brilliant engineer who built
amazing race cars that challenged the barriers of Bonneville Land Speed
Records is gone. Just like that.
Yogi Berra pointed
out that, "It ain't over 'til it's over." Last night at the
San Diego Roadsters Club (SDRC) meeting I discovered the horrific truth
of that statement.
Bob wanted a record,
and built a car to go after it. Keenly into aerodynamics and widely
known as a stunning engineer, he fashioned a high tech frame and wrapped
it in a flawless body — no holes, no bumps, no blemishes of any
kind. He even installed an on-board breathing system with a high-pressure
oxygen bottle so he wouldn't need a parasitic opening for intake air.
He ran it many
times, always chasing speed.
Fast forward to
August 1969, the day of his final run. What follows is a somewhat fanciful,
although essentially factual, account of what happened. I say "essentially"
because I was not there and have only assembled some of the details.
I write this so that perhaps you will learn, as I did last night, that,
"It ain't over 'til it's over." The story of Bob's death most
certainly saved my life, if not directly, then at least by making me
more respectful of what we do out there.
That 1969 event
had been a frustrating meet. To get more speed in the car, they had
switched from alcohol to nitromethane, but inexplicably the motor would
not run right. Seems some kind of gunky stuff kept forming in the fuel
lines. They had to keep flushing everything out. Bob was not to be deterred.
Once it was all purged, the motor responded eagerly.
So off they went
to the starting line.
Bob suited up
and climbed into the car. The motor responded with the erotic cacophony
of disjointed explosions that only Pop (nitro methane) can make. Put
the hammer down, though, and the confusing mayhem transforms instantly
to "orderly" mayhem — that is to say, "hang
on!"
Bob left the line
that day with a strong burst. Climbing up through the gears, the motor
ran cleanly, now free of the strange gunk that had clogged its arteries.
The very same gunk that had done such a perfect job of sealing the fuel
tank from alcohol leaks. The gunk that was no match for the corrosive
temperament of Pop.
The fuel began
to leak. And leak. And leak. And Bob kept his foot into it, hammering
his ride toward the 300 range. Unaware of the evolving scene, just four
feet back.
Funny things happen
to airflow. Unpredictable things, even with the best engineering. The
investigation would reveal that pressure under the car had somehow gone
negative, pulling the belly pan down from the firewall that separated Bob
from the engine compartment behind him. Drain holes in the belly pan,
made tiny to lessen wind resistance, were not able to expel the gathering
fluid, and it continued to collect. At the back of the car. We're accelerating,
remember?
At last, through
the final lights. Off the gas.
Like me, Bob probably
contemplated the scene for a moment before tossing the laundry. Your
car may be fishtailing or bouncing, or it may be wonderfully solid,
as if "on rails." Either way, when the chute blossoms, reassuringly
slamming you forward into the belts, the release drains every cell of
your body.
Phew! It's over.
I'm safe! All we do now is wait, as it all slows down.
I'm sure Bob was
feeling the same kind of relief as the sudden deceleration sloshed the
puddle of nitromethane forward and the fuel ignited on the hot exhaust
manifolds. The burning fuel immediately found its way under the firewall
and into the driver's compartment. A few seconds later it melted the
high pressure oxygen line, only insuring that it would all happen more
quickly.
It was over so
fast that when the car rolled to a stop moments later, there was no
hint that the car was on fire, or had been on fire. Witnesses 50 feet
away saw no problems. Until they got closer.

Thank you, Bob.
And thank you to the men who told me that story. I had been thinking
that with a good coat of paint, my half-rusted floor boards would probably
be okay for one more season. But after last night, the entire car is
coming apart for a complete Magna Flux and re-do. And brand new floor
boards, firewall fixtures, and wiring routing.
This is serious
s... And, "It ain't over 'til it's over."
Always The Student,
Jim
