n
his role as Group Manager of Drag Racing, Don
Taylor oversees GM Racing's NHRA POWERade and
Sport Compact motorsports programs with responsibility
for administering engine, aero and chassis resources.
He also manages GM Racing's far-reaching Safety
Program. Taylor's 17-year tenure at General
Motors includes serving as GM Racing's business
planning manager and group manager for NASCAR
Winston Cup, Busch and Craftsman Truck Series
programs. In addition he has developed and implemented
innovations such as the use of the production
Vortec V8 engine in the ASA stock car racing
series.
DRO: Describe
the progress of the GM DRCE III.
Taylor: The current engine has been out there for many years. It was time to give it a second look and make it more in line with the needs of what the race teams are looking for today. The new design will have built-in features that in the old design, teams were trying to cobble in by hand. The other thing we want
to do is improve the design so that we can minimize casting problems
and reduce the prep work that teams are doing. The goal is to help them
lower their costs and the time it takes to get these engine parts ready
for competition It should be on the track later this year.
DRO: What are some of the technological elements GM Racing provides to its
drag-racing teams?
Taylor: GM Racing
can help the teams to understand the engineering
behind their vehicles in a number of ways. With
some basic knowledge of aerodynamics at 200
m.p.h., the stress in the vehicle's structure
coming off the line and how a shock absorber
behaves, a team can be better equipped with
the tools to tune their car. We try to help
them to help themselves. But the biggest emphasis
for us, and the teams, is on the engine. The
engine design is really a joint effort between
GM Racing and the teams. The engine block and
cylinder-head design, once developed with input
from the teams, must be submitted by the manufacturer
for approval by NHRA. We must be confident that
we are creating a piece that is of high quality,
that is cost effective and that will have some
life to it so that it can be competitive for
several years. The body is something else that
only the manufacturer can submit. It has to
be good from the start. Once it's out there
on the racetrack, NHRA is not going to let you
make changes on it from race to race, and sometimes,
from year to year. It has to be well balanced
and manufactured with the strength to survive
a season of competition. We do a lot of aerodynamic
refinement in the GM wind tunnel to make the
body competitive. This means low drag and balanced
downforce, front to rear. At the same time we
must of course stick closely to the production
design of the Grand Am and Cavalier, and to
the NHRA templates and measurements for those
brands.
