@pakk: that sounds strange and for sure too long! Which speedo was that exactly (there is no just "SXX"...) and to which distributor did you send it for repair?
@ark: this is a standard SXX TC V2 in Ronald's car.
For indoor races some drivers are lazy to mount the fan as the SXX TC V2 can work without if all is set right even in modified, but it's at it's limit and I keep reminding the guys that cooler is better and that they should install the fan... for outdoor the fan is a must have!
@M3dreamin2008: yes, the SXX TC V2 (80955) is the right speedo for you.
