Since the IDRC’s inception in 1998, the IDRC has taken pride in the development of the heads-up classes of import and sport compact drag racing. As new organizations have come and gone in the modern drag racing arena, the IDRC’s rules and classes have in the past and will for the future serve as the standard for all other organizations. We are not better people, we are just racers making rules for the benefit of the racers.

Recently, another compact drag racing series made a rule change to split the PRO class into a PRO Class and a PRO V-8 Class. Although we understand the pressure exerted by some of the racers and sponsors involved with this class, the IDRC does not agree that the other organization’s program change is the best for the sport.

The other organization’s solution will result in at least one and possibly two incomplete fields of vehicles. Incomplete fields have always plagued the Pro Class, as there are only a handful of Pro Class cars in existence. For 2002, the IDRC has contacted a number of Pro Class racers and looked at all possible solutions. We believe that our solution is the best solution for ALL of the racers.

Effective immediately all V8 competitors will be assigned a maximum turbocharger compressor wheel inducer diameter based on their competition weight. Heavier V8-powered vehicles will be allowed to use slightly larger compressor wheels in their turbocharger compared to the lighter . The intent of this ruling is to bring parity to the Pro Class without shrinking the field size.

2350 pounds 63.5 mm (twin) / 89.8 mm (single)

2400 pounds 64.5 mm (twin) / 91.2 mm (single)

2450 pounds 65.5 mm (twin) / 92.6 mm (single)

2500 pounds 66.5 mm (twin) / 94.0 mm (single)

2550 pounds 67.5 mm (twin) / 95.4 mm (single)

2600 pounds 68.5 mm (twin) / 96.9 mm (single)

2650+ pounds 69.5 mm (twin) / 98.2 mm (single)

Comp Weight = weight of driver plus vehicle @ scales after run

All national IDRC protest procedures will be followed for inspection and verification.

Nitrous-only V8-powered vehicles will still need to weigh a minimum of 2250 pounds with driver. These above compressor limitations were obtained through both real-world and predicted performance considerations. The IDRC will adjust these as needed to establish additional parity if needed in the future.

For positive-displacement type superchargers or blowers, future overdrive percentage and blower displacement limits will be set as more real-world performance data is gathered.

· A Separate Pro-V8 Class

This is other organizations solution to the V8 dilemma. Another organization created a second Pro class just for V8s. In our opinion, this solution, as any solution has its Pros and Cons.

The Pros: An separate Pro-V8 class eliminates the parity issues for the remainder of the Pro Class racers.

The Cons: There are currently only four known Pro V8 type vehicles in existence. Until there are more of these cars built, the Pro V8 class will never make a full field. It may also be hard for the original Pro class to muster a full field.

· Boost Limits for V8

The Pros: A way to effectively limit the power on V8 competitors if correct boost limitation is in place.

The Cons: Every vehicle would need a mechanic boost limiting pop-off valve and/or a tamper-proof data logging device to verify boost limits were not exceeded. This could be difficult to implement and enforce.

· Compressor Inlet Restrictions

The Pros: A way to effectively limit power on V8 competitors if correct size compressor wheel diameter is selected.

The Cons: Some additional cost to Pro Class racers to retrofit a second set of turbochargers.

· E.T. Breakout for V8s during eliminations

The Pros: Adds instant parity.

The Cons: Takes away the all-out, heads-up aspect to the class. May be hard for the fans to follow if a V8 racer were to lose on a breakout.

· Additional Weight for Pro-V8

The Pros: May be able to gain additional parity if V8 cars are heavier and the other cars are lighter.

The Cons: V8 would probably need to add an excessive amount of weight. Could possibly decrease the safety to driver and sport.
