2010 TORC/USAC SPORTSMAN DIVISION UPDATES
-
The 2010 TORC/USAC Rule Book will be available at
www.usacracing.com.
-
Rule changes are in bold, the old rule is strikethrough.
Please read it carefully. Below are highlights for the
Sportsman teams.
Formula 4x4 & Classix:
-
These classes will race at the same time for their own
purse and points. Work is ongoing to open up the rules in
Formula 4x4 to allow “Stadium Trucks” to compete. For now,
direct questions on this to the class rep. David Miah @
313-805-2679. Going forward it is very important to
cosmetically clean up some of these vehicles.
Enduro Truck:
-
Cross over exhaust is not allowed. All trucks must use
duel pipes with a 1 ˝” x 24” inch restrictor pipe. Exhaust
must be welded together and well mounted to chassis. If
the restrictor pipe is lost during competition penalties
may be imposed. Aftermarket headers are not allowed.
Anti-wrap up bars are not allowed.
1600 Buggy:
-
With the single port engine a carburetor spacer (carb. to
intake) of no more than 3/8” inch will be allowed, must be
straight bore only.
Super Stock Truck:
-
Any OEM steering box is allowed as long as the pitman arm
location does not change significantly. The fifteen year
rule will no longer apply. OEM cab floor and firewall must
match frame and be mounted in the stock location. Only
very limited trimming of material will be allowed. The
remainder of the OEM cab is not required. Updating of the
body is allowed as long as the stock body lines are kept
and it is done in a professional way. External wet sump
oil pumps are not allowed. Bypass shocks of any kind are
not allowed. All trucks must have a radio and a spotter.
Limited 2WD:
-
This class will continue in 2010 with no rule changes. All
cars must have a radio and a spotter.
Limited 4x4 (Ultra 4x4)
-
will be a separate class in 2010. They will use the 2009
rules but can now use the Limited 2WD engine package and
must be 10 pounds per cubic inch minimum. PRO 4x4 trucks
will be allowed to participate in this class. These trucks
must use an open front diff. and be 10.5 pounds per cubic
inch. They must also use the Limited 2WD engine package
with an automatic transmission and D.O.T. tires. Race
numbers will be 400-499 series. In the interest of
competition rules may be changed at any time. Limited 4x4
will run at the same time as Limited 2WD. Car counts in
2010 will impact the future of this class. All trucks
-
must have a radio and spotter.
Super Buggy:
-
Starting grids will use a twelve car inversion. All cars
must have a radio and a spotter. No other rule changes for
2010.
General rule updates for all Sportsman classes:
-
The competition yellow will be used with points awarded,
two for first and one for second. ALL classes must have
looped bumpers, body mounts and side bars.
-
-
Only SFI 45.1 roll bar padding will be allowed.
-
-
Mud flaps are required on all truck classes including
Classix. They must be at least as wide as the tire, touch
the ground and be made of semi ridged plastic, not rubber.
-
-
The maximum exhaust decibel reading of 100 (50 feet from
trackside) will be strictly enforced in all classes.
-
-
Brake lights will no longer be required. A minimum of one
taillight is required.
-
Windshield screens with a maximum of a 1 ˝” x 1 ˝” opening
will be required in all classes.
