Stall Test
#28709 from Chris Doodson · Rule change · TB 20-06 (2020-06 Fastrack)
In Appendix F., SIR testing procedure:, change as follows:
"The system is to be tested as is and the result is considered “as qualified or raced”. It is the
responsibility of the competitor to present a system that can withstand every possible scenario that
would or could result in a failed SIR stall test. The intake system shall be visually inspected for devices
and design that could result in induction of additional air that did not pass through the SIR. Introduction
of air behind the SIR by any means is prohibited. All inspections must be done in "as qualified or raced"
condition."
