The rpm range is right.. go to the VDO site and snoop around?
The seller is Summit Racing. In the ad they list a phone number: 800-517-1035 begin_of_the_skype_highlighting**************800-517-1035******end_of_the_skype_highlighting. They might know the answer to your question.
Apparently that is a Skype number. I have no idea whether it will work on a regular phone. If not, their web site will have a number to call.
