J & J Racing, Ltd.
has been serving the motorsports industry since 1972. Below is
a list of a few of the services we specialize in. We are dedicated
to being the best at what we do...
Gearbox Dyno...When a transmission is on our dyno,
utilizing infrared pyrometers, we monitor temperature at a
minimum of 12 key areas. This allows us to see potential drag
problems in the gearbox before we ever take it apart. Once the
gearbox has been completely blue printed to our specifications
we are able to run the gearbox again on the dyno to document
the decrease in drag. In addition, this is also a useful
quality control tool to insure that the gear box runs properly
in all gear selections and has no leaks.
