Has anyone seen this kit from Garrett yet?
http://www.turbobygarrett.com/turbobygarrett/products/Accessories_continue_speed_sensor.html#That is very cool, to be able to monitor and even potentially log the shaft speed of your turbo to match to the compressor map. This way you could ensure that you never overspin the turbo and determine the efficiency by comparing the PR and shaft speed to the map.
Anyone know what it costs?
