The University of Texas continued to host the event from 1982 to 1984 as the popularity and number of participants grew. In these subsequent years, UT moved the Formula SAE competition to other parking areas that included elevation changes and driveway aprons that forced the use of functioning suspensions. The event became international in 1982 with the entry of Universidad La Salle team from Mexico City. The significant rules changes for 1982 were: 1) a displacement limit of 600 cc (300 cc for Wankels), but the 1 inch diameter restrictor rule was retained, 2) a requirement for 4-wheel independent suspension (Mini-Indy did not have any suspension rules), and 3) the addition of a temporary “B&S” class of vehicles that were originally designed for Mini-Baja, had to retain the 8 hp Briggs & Stratton engine, and did not need to comply with the 4-wheel independent suspension rule. Formula SAE continued to be an international competition when the team from Universidad La Salle returned. With the only engine restrictions being a displacement limit of 600 cc and a 1-inch maximum diameter for the intake, creativity flourished. Also in 1983, the temporary B&S class was eliminated, the University of Texas at Austin entered the first composite Formula SAE vehicle and Marquette University entered the first turbocharged engine. The rules allowed a Formula SAE car to compete for two years in recognition of the effort required to build and test a quality car. This also allowed students the experience of re-engineering and improving on design elements that did not work. The rules for 1984 specifically allowed turbochargers, superchargers, and use of nitrous oxide but the engine had to breathe through a 25.4 mm exit bore of the carburetor casting (1984 was well before electronic fuel injection). Engine intake restrictors were later tightened as cars became faster year over year as knowledge was passed on within and between teams. Also, a 65-100 inch wheelbase rule was promulgated, as was a rule requiring all vehicles to have a “body that resembles a formula car”. The Formula SAE field had grown to eleven cars in 1984, so the University of Texas at Austin decided that the competition had matured sufficiently that it was safe to pass it on to other hosts.
