Valve Cover Restraints To Be Mandatory
Courtesy of NHRA
Pressurized Bottles Also Addressed
Effective Oct. 21, commencing with the start of the O'Reilly Fall Nationals,
all engines in the NHRA Funny Car and Top Fuel classes must be equipped with
a valve-cover restraint capable of restraining components such as head
studs, spark plugs, and pushrods in the event of engine failure (see
official rule revision below).
NHRA has petitioned the SFI Foundation, Inc. to develop a minimum
specification for these valve cover restraints. NHRA anticipates this
specification will be in place, and that all such restraints will be
required to meet the specification effective Jan. 1, 2000.
Questions regarding product availability should be directed to Mr. Jeff
Giovino of the NHRA Technical Department in Glendora, California at (626)
914-4761 Extension 286.
NHRA also is asking all teams to verify that all pressurized bottles on the
race vehicle are stamped with a DOT-1800-pound rating. Inspectors have seen
a few onboard fire extinguishing systems in tech that had non-rated
containers. Check yours now and avoid problems in tech inspection.
