2023 Road Atlanta Impound Report


Date:

Car Number:  176

Event:

Road Atlanta

Team Name:  JSK Racing

Event Director:

Dana Morrison

Team Captain:

Tech Inspector:

Protest Details: 

 

 At the conclusion of the 2023 Road Atlanta Race ChampCar Officials measured the bore and stroke of the top three finishers. A discrepancy was noted with the stroke of the engine in the JSK Racing car 176.

 ChampCar Officials asked the Team Captain about the discrepancy. The Team Captain claimed he had welded and re-ground the crankshaft rod journals to “re-profile” the motor’s stroke. During several additional conversations, ChampCar Officials asked about the impact of the additional stroke on other items in the rotating assembly. The Team Captain stated that the original replacement pistons were no longer available for the engine. He ordered aftermarket pistons and specified a different placement of the wrist pin to account for the increased stroke and re-position of the height of the piston in relation to the block deck height.

 

 

Tech Inspector / Event Director Final Findings:

 

Rule 4.7.1 states:  Teams may replace any worn, broken, ventilated, impaled, defective, or bent beyond all recognition parts on their car without affecting their total points so long as it’s an OE or OE equivalent part for that car’s specific model.

 

ChampCar Officials determined that the altered location of the wrist pin in the pistons violated the OE specifications for the part.

 

ChampCar disqualified the team and removed them from their finishing position.
