NHRA TECH BULLETIN
GLENDORA, Calif. (Feb. 18, 2010) --NHRA's technical department made two announcements today effective at this weekend's NHRA Arizona Nationals in Phoenix, Ariz.
ELECTRIMOTION SHUTOFF RECEIVER
NHRA has temporarily suspended mandatory use of the Electrimotion Shutoff Receiver while NHRA works with the manufacturer to meet driver requests.
Top Fuel and Funny Car teams, after the just concluded Pomona event, raised certain concerns about the automatic shutoff process, including potential wear on certain engine components, and a desire among some drivers to keep their traditional routine in place at the end of the track and manually shut down the car when they were fully capable of doing so. As a result, NHRA and Electrimotion are currently working to develop an override to the Shutoff Receiver when both parachute handles have been enabled. When both chutes have been pulled, the driver will be able to shut down according to his or her normal procedures rather than having the automatic device shut off the vehicle. The override kit is expected to be available prior to the Gainesville, Fla. event which begins March 11.
The automatic shutoff procedure was implemented as a safety measure to stop a vehicle in the event of driver inability to do so. NHRA still encourages the use of the automatic shutoff even during this time period when its use is not mandatory. Therefore, NHRA will install Electrimotion Shutoff Transmitters to accommodate those teams wishing to continue to use the shutoff receivers.
The Electrimotion Safety Shutoff Controllers on Top Fuel and Funny Car vehicles, activated in the case of burst panel rupture, fire bottle activation or activation by the driver, will remain mandatory.
ALAN JOHNSON PERFORMANCE ENGINEERING (AJPE) SUPERCHARGERS
The NHRA Technical Department impounded superchargers on Top Fuel and Funny Car vehicles at the NHRA Winternationals last weekend at Auto Club Raceway at Pomona. This week in Phoenix, NHRA inspected each impounded supercharger with a representative from the applicable team. It was determined that certain AJPE Superchargers do not meet certain NHRA specifications. In addition, the NHRA Rulebook states that all engine component development, including superchargers, must be submitted to the NHRA Technical Department for review. The subject AJPE Superchargers were not submitted to NHRA Technical Department for review. Therefore, AJPE Superchargers that do not meet the current specification cannot be used in competition. This information has been conveyed to all affected teams and to the manufacturer, and NHRA is informed that they are working to resolve the issue.
