A 'good' pit stop at Indy was less than one minute at that time. The first pit stop fuel only was timed at 17.9 seconds. The second fuel only stop was 24.9 because there was less fuel pressure in their gravity feed system. The car needed no tire changes, but the Woods made sure the rims and spinners were carefully prepared for that possibility. Tread depth was also checked during that pit stop.
BTW, the Lotus 82 had a 58 gallon fuel tank. Wood felt it could optimally fill the car in about 15 seconds- meaning they had a 4 gallon a second fuel rig.
Gah! Lotus 38!!!! ^_^
Dad raced a 1/24 slot car BITD of one of those. Had a T-Car in a Heinz Happy Soup livery- got the label off one of my cans, and then the white and orange race car. Built a Black one for a friend.
They were VERY popular for those purposes BITD, no real body, all chassis.
