To ensure complete impartiality, the cars were qualified and race lap times recorded back in January, long before teams selected their cars. Once selected, the cars in the field were inverted by qualification time and the starting grid was set.
Starting grid for SIP round #3 at Shelby-Hendrix Speedway:
1st) #1 Chaparral 2F - DMS Racing
2nd) #8 Ford GT40 - D&D Racing
3rd) #50 Lola T70 MK3B - CAT Racing
4th) #6F Ferrari 512S - Slothead racing
5th) #57 Porsche 917 - T-County Lug Nuts
6th) #6L Lola T70 MK3B - Racing Bandit
7th) #3 Ferrari 330 P4 - Downundathunda
8th) #4 Chaparral 2F - Oregon Donors
The computer based race simulation was set for 40 laps with each car’s recorded time for that lap being used to determine when it moved from its current track location to the next location. Three of the seven track sections (turn 2, hairpin turn, and loop turn) are no passing zones where cars can catch up to and follow, but not pass other cars. In the other sections (start straight, turn 3, back straight, and finish straight) cars can make passes and gain or lose positions.
DMS Racing’s # 1 Chaparral took the green flag to start the race and with no traffic to deal with got out to a decent lead. The first pass took place on lap 1 when the #3 Ferrari of Downundathunda overtook the #6L Lola of Racing Bandit on the back straight to move into 6th place.
Despite close battles for position, the next pass didn’t take place till lap 9 when the 3rd place #50 Lola of CAT Racing got by the #8 Ford GT40 of D&D Racing to move into 2nd place. At this point the DMS Racing Chaparral had a 1.7 second lead, but the CAT Racing Lola was on the move and got past the DMS Chaparral on the back straight to take the lead on lap 10.
Lap 15 race order: 1st - CAT Racing, 2nd - DMS Racing, 3rd – D&D Racing, 4th – Slothead Racing, 5th – T-County Lug Nuts, 6th – Downundathunda, 7th – Racing Bandit, 8th – Oregon Donors.
The field maintained this order till lap 24 when the #1 Chaparral of DMS Racing got out of shape and ran back to back slow laps allowing the entire field to get by it. On lap 25 the #6F Ferrari of Slothead Racing passed the #8 FordGT40 of D&D Racing to settle in 2nd place. But while the Ferrari had been battling with the Ford GT40, the #50 Lola T70 of CAT Racing had obtained a large lead and could not be caught. The rest of the field became very tightly packed together but none could muster the speed in passing sections to get by cars they trailed through no passing sections. No other passes took place during the final 25 laps of the 40 lap race.
Final race order:
1st) #50 Lola T70 MK3B – Cat Racing
2nd) #6F Ferrari 512S - Slothead Racing
3rd) #8 Ford GT40 - D&D Racing
4th) #57 Porsche 917 - T-County Lug Nuts
5th) #3 Ferrari 330 P4 - Downundathunda
6th) #6L Lola T70 MK3B - Racing Bandit
7th) #4 Chaparral 2F - Oregon Donors
8th) #1 Chaparral 2F – DMS Racing
With this type of simulation an inverted field can become nearly completely flipped in a 40 lap race. But, when the cars are very competitive with each other (as in this field) a few cars can become so tightly packed together they create a traffic jam other cars cannot get past. The data shows that the #8 Ford GT40 of D&D Racing and the #57 Porsche of T-County Lug Nuts were separated by less that a quarter of a second from lap 26 on. Despite being able to turn faster laps the Porsche was not able to get by the Ford GT40, and these two cars battled so closely the rest of the field was held at bay behind them.
The lap 9 pass by the #50 Lola T70 of CAT Racing when it got past the #8 Ford GT40 of D&D racing proved to be the move of the race, allowing CAT Racing to pull away and win the race.
I don't have an online image posting account, but if anyone wants me to send them photos of the track and cars to post for me, let me know. I can send you a few using a PM.
