An evolution model from the Bel Vector Europa 966 which I used in the Swede Demon.
The 966Rshould give a better more sensitive range and less false alarm at the same time.
After law changes per 01-01-2004 this device is no longer being used.
Subaru boost gauge.
The gauge uses Mpa indication instead of bar.
Sorry for the fuzz, will post better picture later.
