For street use only, the Accusump's only merit is as a pre-oiler if the car has set for a while since last running the motor. That in itself if probably not worth the cost of investing in an accusump. However, for taking the car out on an open track day, Auto-X or whenever pushing the car hard with heavy lateral G's, I feel it is well worth the money. In such situations, the
oil pump can run dry when the
oil pick up gets low in lateral G's, and at a time the motor is already stressed. An Accsump will deliver
oil for up to 60 seconds if the oil pressure drops.
For just street use only, I would recomend adding the thermostat and NOT the Accusump.
