|Daytona 1989, practice. The high downforce 956 derived nose was tried. Also note the diveplanes and very high rear wing flap angle; evidence of an alternate theory to achieving lap times around Daytona.|
for the race it was decided to use the low drag setup (note rear wing
flap angle and compare to above) and the corresponding stock
1989’s Daytona 24 was unfinished business. The year before the Busby team had come to within a lap of winning the race after having qualified on pole. In 1989 the team lined up for the start in 12th position overall, though leading the field were the wickedly quick Nissan GTP ZX-T and Jaguar XJR-9. At the start and throughout the first half of the race the battle was between the Nissan GTPs, Jaguar XJR-9s and #86 Bruce Leven Havoline Porsche 962. The #86 Porsche would drop away from the lead group by ╝ distance but rising into the background, if not into contention, was the #67 Busby/Miller car driven by Bob Wolleck, Derek Bell, and John Andretti. The 1989 race was unique because just before half distance fog dropped over the circuit leading to a red flag period that ended up lasting four hours. With the restart the lead (and only remaining) Nissan resumed in first place but by hour 19 retired with a blown engine letting the #67 Porsche 962 past and into the top spot. But the #60 Jaguar XJR-9 of Price Cobb, John Nielsen, Andy Wallace, and Jan Lammers gave hard chase and but for a spin by Cobb and rising engine temperatures they ultimately fell just 2 minutes shy after 24 hours of racing.
