Question on restrictor plate

by Andy Y » Wed, 05 Apr 1995 04:00:00

I was just wondering, what is the restrictor plate for in Nascar.  Do they use
them in real life.  And why is talladega the only one with it on?  

I also looked at the lap record and it was about 216.  Now I'm quite sure that
this is impossible with the restrictor plate on so should it be off anyway?

I would be grateful if someone could satisfy my curiosity.
Cheers!

The restrictor plate is an aluminum plate with four 7/8 in. holes in it.
It is placed between the carbeurator and the intake manifold on a real
Winston Cup car.  The plate was mandated by NASCAR in 1988 at it's two
superspeedways, Talladega and Daytona, to keep the speeds below 200 mph
and hopefully keep them on the ground.

This came about as a direct result of Bobby Allison's crash in the 1987
Winston 500 at Talladega.  Allison spun after cutting a right rear tire in
the tri-oval.  The car became airborne and crashed, vertically, into the
spectator fence about 100 feet from the start-finish line.

The original plate had 1 in. holes, and has progressed to the 7/8 in.
plate now in use.

The record is 212.809 mph, set by Bill Elliott in qualifying for the race
mentioned above.  It would be impossible to get this speed with the plate on.

Yes, there is really a restrictor plate in NASCAR and a "similar" thing on
the simulation.  Edit the taladega.txt and change the 1 to a 0 in the
speedway line (about 3 or 4 lines down).  You will zooooooooom!  The track
record 212+ was set by Bill Elliot several years ago with  more horsepower
than is possible now.  BTW, get the 1.2 patch.
