BoP Rationale
#32321 from Club Racing Board · Member advisory · Minutes (2022-03 Fastrack)
All Mini's were required to run a restrictor when the BOP change was made 2 years ago. The BSAC reluctantly allowed the 07-10
Mini's which did not utilize the header to run without a restrictor. The BSAC was advised that these cars would be "completely
uncompetitive" without the header. Shortly after this change was implemented the ECU was hacked which permitted improved
tuning. Current evidence suggests that a non-header car with no restrictor would still have an advantage over a header car with
a 40mm restrictor. Past experience suggests that header availability is a temporary issue. Also, favorable changes take effect
sooner than unfavorable ones allowing competitors time to acquire a header (if that is their choice) in advance of the rule taking
effect.
