The dynoKRAFT MPS170 engine dynamometer offer exceptional high measurement precision together with best-in-class DAQ system and high speed Sport Devices PWS-HS eddy current brake power supply.

The dynoKRAFT MPS170 can be used to test combustion engines without the need for expensive engine test bed. Only engine specific adapter plates are required.

Another useful application is engine testing in snow mobiles and jetski.

It is fully adjustable and can be fitted to most engine stands with affordable clamping system.
