Event 5 was the final MirrorCross of the
season, held at the large and fast Mineral
Wells Airpark site in Mineral Wells, TX. This
is where we run parallel courses, with side by
side drag-race-style starting lights. In the results
you can see how close to a perfect 0.50-second
start or red light breakout was happening, and
our fastest 60-foot times were turned in by the
Boxster GTS (due to its quick-shifting PDK
transmission), the GT3 (due to its horsepower),
and the 914 2.0 (due to its good gearing).
Eleven of the 83 cars at this event were
Porsches. Class P1, the early 911 and 914
class, saw a hard-fought battle between the
super fast 1972 911S driven by Ed Mayo and
the super handling 914 2.0 driven by Mark
Schnoerr. Times were very close, but the win
went to the 914 this time. In class P3, Fran
Ussery and Carolle Liu traded places and each
P1 - 'PCA 1'

won on one side. Fran just
edged our Carolle for the win.
Class P4 saw two
new drivers sharing
a Boxster GTS: Jake
d’Fonseca and Daniel
Finckbeiner, making
Doug Edney work his
996 hard enough to
decide that it’s time for
a suspension upgrade.
Jake took first, Doug second, and Daniel
third. Class P5 saw Owen and Holli Coulman
driving their 996 GT3 and 996 Turbo Cab.
Owen pulled out the win.
The Performance index-adjusted times
ranked the top three Porsches as Owen, Mark,
and Ed this time. Owen was also sixth in overall
event PAX time. In the Ladies’ Performance
indexed classes, Sigrid and Holli came in third
and fourth overall respectively.
