Thank you for your letter. Data obtained at the 2021 June Sprints shows that the three Stohr chassis that were equipped with
AiM data boxes—the referenced 1615cc car, a 1455cc car, and the 1355cc car that won the 2021 P1 National Championship—
had acceleration rates that were very closely matched and were at no disadvantage to the two 2500cc Elan DP02s and the
converted FA 1615cc Swift 014a that were fitted with the data boxes. The national championship race at Indianapolis refutes the
notion that a Stohr cannot compete with a "high downforce" DP02. An individual car's deficits in braking power, cornering
performance, and right/left transitional handling capabilities are not subject to the SCCA's BoP process and are not remedied by
increasing the car's restrictor size. If concerns remain about the referenced 1615cc car's weight and restrictor size despite the
acceleration rate data, then the engine table provides an alternative: a car using the 1455cc engine has the option to run
