DragPro Eliminator

Pro Modified  is reserved for naturally aspirated full bodied factory production body styles.
Nitrous oxide, superchargers, and/or turbochargers are prohibited in Pro/M.

Pro/M is formulated on an 8.60 base index.
Use the 8.60 Naturally Aspirated Gasoline Weights Table to find minimum weight for your particular vehicle.

Pro Competition (Pro/C)

Pro Competition  is open to all naturally aspirated full bodied, altered, and dragster type vehicles.
Nitrous oxide, superchargers, and/or turbochargers are prohibited in Pro/C.

Pro/C is formulated on an 9.40 base index.
Use the 9.40 Naturally Aspirated Gasoline Weights Table to find minimum weight for your particular vehicle.

Body:

Pro Modified/Competition vehicles must retain full body exterior appearance.

All body components such as roof, hood, doors, fenders, bumpers, etc. must remain in place.

Fiberglass and/or aluminum body components permitted.

Doors must remain functional.

Must currently meet hosting facility's safety guidelines.

Suspension:

Air bags may not be used to replace coil springs, leaf springs, or torsion bars.

Any make engine permitted.

Minimum gross intake valve lift must be equal to no less than 31 percent of the intake valve diameter.

Example: If intake valve diameter is 2.02" then multiply 2.02 by .31 and round to the nearest thousandth to find minimum acceptable gross valve lift of .626" or

2.02 x .31 = .626

Engines having valve size/lift combinations where the gross intake lift does not meet the minimum specification will not be disallowed from competition. In these instances vehicles will be factored using the minimum valve lift specification for the intake valve diameter being utilized.

Example: If running a 2.02" intake valve with less than .626" gross lift, .626 will be used in the Engine Performance factoring formula to assign the appropriate minimum weight to the vehicle.
