We work on all things fast but we cut our teeth on high-performance Mazdas. With years of experience, we’ll get every ounce of performance out of your Mazda. We have the ability to perform compression test on rotary engines, handy for Formula Mazda cars. Compression numbers can be separately seen for all rotor faces. The device also corrects for the Mazda specified cranking rpms of around 250. Before you buy a rotary, we highly suggest getting it tested.
