9:2 DATA RECORDERS
Data recorders may be used (per Class Requirements) to record
functions of a vehicle so long as they do not activate any
function on the vehicle. All data recorders manufactured after
Jan. 1, 2006, must be NHRA-accepted. A current list of NHRA-
accepted data recorders is available on NHRARacer.com.
Fifth-wheel sensing devices prohibited on all vehicles (includes
wheelie-bar wheels). All lines sensing flow, pressure, etc. of fuel
or oil must be metallic or steel braided. Ride height sensors
prohibited unless specifically permitted by Class Requirements.
Cylinder pressure sensors prohibited in all classes.

Any device (mechanical, hydraulic, pneumatic, electrical, optical,
etc.) other than OEM-type that assists in determining track
location of the competitor’s own vehicle or opponent’s vehicle
is prohibited. Only OEM-style mirrors, mounted in conventional
fashion, permitted.

For non-OEM data recorder applications, the transmission or
display of any vehicle performance data (e.g., wheel speed,
driveshaft speed, vehicle acceleration, etc.) gathered or
processed by the data recorder, to the driver or any remote
location, during the run, is prohibited. This data may be reviewed
(printout, replay, etc.) only after the run. Discovery of a device
that displays, indicates, or transmits “on track,” “track location,”
or “elapsed time”-type data will be grounds for immediate
disqualification from the event, loss of all NHRA Camping World
Drag Racing Series or Lucas Oil Drag Racing Series points for
the season, and suspension from all NHRA Championship Drag
Racing events for remainder of season. Additional penalties may
be imposed at the discretion of NHRA. Devices may be removed
at any time at the discretion of the NHRA Technical Department.
