Jaguar XJR Dyno Pulls

My XJR on the Dyno. Only modification is a upper supercharger pulley for 1.5lbs more boost. 7500 miles on the oil when these pulls were performed. 21500 miles on the car itself. The car was running rich as well. I will follow up a new dyno video once my ECU has been tuned. I am expecting gains of over 25rwhp from the tune. If you are wondering how I calculated the 425.5 HP at the flywheel, this is what you do: Take the RWHP and multiply that number by one-hundred. Then divide that number by the efficiency of your transmission. My car is automatic so I factored in a 20% drivetrain loss. The number after you divide is your flywheel horsepower!
