DragPro Eliminator

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 Competition Class Weights and Factor Chart

(Actual Cubic Inch x .75) + 150 x Intake Valve Diameter x Gross Valve Lift = Engine Performance Factor

Example: An engine of 468 c.i. with a 2.195" intake valve and .728" lift equates as;
468 x .75 = 351.00
351.00 + 150 x 2.195 x .728 = 800.58
Round this number to 801

An Engine Performance Factor of 801 falls under F-6 and would have a minimum weight of 2800 pounds.

Pro/C is technically formulated around a 9.40 base index.
Actual performances will likely be in the high 8 to low 9 second range depending on hosting altitudes.
Power to Weight Formula Minimum Weight Engine Performance Factor   Power to Weight Formula Minimum Weight Engine Performance Factor   Power to Weight Formula Minimum Weight Engine Performance Factor
F-1 3300 928-956   F-6 2800 783-811   F-11 2300 638-666
F-2 3200 899-927   F-7 2700 754-782   F-12 2200 609-637
F-3 3100 870-898   F-8 2600 725-753   F-13 2100 580-608
F-4 3000 841-869   F-9 2500 696-724   F-14 2000 551-579
F-5 2900 812-840   F-10 2400 667-695   F-15 1900 <-550

Body:

Pro Competition vehicles must currently meet hosting facility's safety guidelines.

Chassis:

Must currently meet hosting facility's safety guidelines.

Suspension:

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

Engine:

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/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.

Fuel:

Gasoline

Interior:

Must currently meet hosting facility's safety guidelines.

Tires:

Unlimited.

Electronics:

Delay boxes are prohibited.
