1985 Ford Mustang, racing in NASA's Camaro-Mustang Challenge class, during the Saturday afternoon race. This was my first time ever racing @ LSIR, having a total of ~35 minutes of total track time prior to the green flag being dropped that afternoon.
Running on 17x9 rims, with Toyo R888 275.17 tires, as I recall (my apologies, but it's been a decade). I was dyno'd that day, showing 250hp/280tq. This was 10hp and 30tq UNDER the maximums allowed for CMC of 260hp/310tq. Weight was 3160, as the car came off the track, minimum allowed was 3150.
This laptime was set during the race, on lap 7.
