I’ve
long suspected that racers way over-do it on the burnout,
but seeing David Reher’s article in National Dragster
and my conversation at PRI gave me an idea for a more
inclusive article about how excessive and/or improper
burnout technique can be killing parts.
When
I started racing the Dodge in 1995 it was a small-tire
car with a leaf-spring suspension, and it needed a long
burnout. That became a habit which remained even after
upgrading to a ladder-bar suspension and much bigger tires,
changes that would make it work better without needing
such long, overkill burnouts. But like they say, old habits
die hard, but I was about to change mine.
The
first part of my burnout epiphany came one night in 2003
at Island Dragway, when my line-locks failed on my burnout
during 1st Round. The tires barely spun; the Dodge lurched
forward with hardly any smoke. I thought I was dead; as
I approached the starting line I kept thinking that I
was going to spin, that I’ll never run the number,
and to be ready to keep my foot in it at the stripe. Instead,
the Dodge dead-hooked and went quicker and faster.
Back
then I had just switched over to Mickey Thompson tires,
and this is when I realized that their sales pitch of
“requires little or no burnout” was true.
Carl Robinson, Motorsports Manager/Race Wheel
Product Manager for Mickey
Thompson Performance Tires & Wheels states,
“In general, and in specific to the M/T products,
a minimal burnout is required to maximize performance.
To be more specific, the elapsed time of the burnout while
being minimal must be appropriate to the conditions. The
hotter the track temp, the shorter the burnout. Excessive
burnout will cause a melting of the tread compound at
the shoulders, increase the potential for "slip"
and decrease tire life.”
So
racers, you probably don’t need to kill your tires
on the burnout. Try keeping it short and sweet. This will
result in longer tire life, and potentially lower staging
temps as well. Those of you who know me know that I easily
get 350 passes out of a set of Mickey Thompson 31 x 10.5Ws,
because I'm not killing them on the burnout.
