The 2002 Rolex Tests are now completed, and much has been
accomplished toward preparing our Lola B2K/10-Porsche for the
demands of this year's Rolex 24 at Daytona. For Day Three of the
Tests, our plan was to sit out the morning session (just two
sessions on Saturday, vs. three sessions each on Thurs and Fri)
while completing
a motor swap. The motor that we ran for the first two testing days
was the same motor that we ran at the Daytona Finale and all
previous and subsequent testing, so it's time for a refresh for that
motor.
After the last session on Friday, the Champion mechanics got the
Porsche gearbox disconnected before the garages closed for the day,
and first thing Saturday morning the gearbox was removed and all
connections released to prepare the old motor for removal. We then
installed what we hope will be our race motor for the Rolex 24, with
the intention of running it in during the final hour of testing
Saturday afternoon. Unfortunately, while the crew worked at changing
motors, the track conditions were absolutely ideal, and almost all
of the top teams set their fastest times of the Tests in the cool
but calm morning air (hence good engine power) and on a rapidly
warming track (good for getting tire temps in the proper range
quickly). Andy Wallace's best time of 1:42.791, set on Thursday,
would stand as Champion's best time of the Tests, good for
seventh-fastest overall.
The race motor will now be removed from the car and put through a
battery of very careful checks to determine if it is sound and
wearing properly, no leaks, etc. It will be set aside and the
previous motor - after a thorough refreshing - will
be put back in the car for all the pre-race testing and practice
prior to the Rolex 24 itself. Then the race motor will be
reinstalled and the final preparations made for the race. In the
meantime, the entire car will be torn down and checked
and rechecked, then built back up, all with the goal of having every
component of the car fully ready for the rigors of the 24-hour grind
on the Daytona high banks.
We know ours is not the fastest car on the Daytona grid, but
experience has taught us that the endurance qualities of the proven
GT1-98-derived Porsche flat six turbo continue to make it one of the
best drivetrain packages in endurance racing. Sadly, this same
drivetrain failed at just over seven hour's distance in last year's
Rolex 24, but not as a result any actual problem with the motor
itself. What put the Champion Porsche-Lola out in 2001 was sand.
Yes, sand - specifically, silica casting sand used to form the mould
which metal is poured into to create our Porsche's gearbox casing.
In this particular drivetrain, the engine oil tank is actually part
of the gearbox casting, rather than there being a separate oil tank
(the current Audi uses a similar arrangement).
The gearbox we chose as our race unit for last year's Rolex 24 was a
relatively new casting, rather than one of our older, more proven
units. During the course of the early hours of the race, pockets of
silica casting sand that had been trapped
within the gearbox metal during the casting process began to leak
sand into the tank, contaminating the engine oil. This sand was
duely filtered out by the oil filter. But more sand was present than
could be held by the filter, and when full
it bypassed (as it is designed to do) directly to the engine - thus
sending sand-contaminated oil directly into the motor - with the
inevitable consequence of damaging the engine, causing it to seize
and fail shortly into Sascha Maassen's opening stint. There was no
fixing this problem and the car was retired. And now you know, "the
rest of the story"...
Stay with us for news and developments as we continue to prepare for
the 2002 Rolex 24 at Daytona.
