Because we race at both NHRA and IHRA tracks, we must abide by rules for both organizations. IHRA states that any car running 8.49 or quicker must be equipped with a "fire system with one nozzle on the driver and one nozzle on the engine". We think that this is a good safety feature (particularly with nitrous) and require it on all PRO 5.0 cars. The bottle size is not specified in the IHRA rule book. These systems are available through the Summit catalog for under $300.
