What is the life expectancy of the e-Ram device, and does it require maintenance?
The only moving parts are the instrument quality rare earth electric motor which is rated for over 800 hours before recommended service (brush replacement) and a metal impeller. It is highly resistant to heat and has sealed no maintenance ball bearings. Because of the low duty cycle (on the race track it is only on for 20 to 40 seconds a lap depending on the road course such as Laguna Seca or Sears Point where testing is done), the e-RAM unit should outlast your engine. We have many e-RAMs in the field since 1998 that are still going strong.
