He was racing with a broken right index finger and his race craft was finally run a supercharged while during wither his team had prepared a supercharged/turbocharged engine. Though the Japanese rules allow only the use of the OEM waterbox and the particular one could not withstand the pressure of the twin charger engine. Since reliability was in first priority Kuriharas team selected the single charger option. Last years spec gave a top speed of 96mph.
