SDM racing pumps come in both the SDM 249 (8″ impellers) and the SDM 649 (8.5″ impellers).

SDM trim nozzles are available for the older Scott junior, as well as the 8 1/4″ and 8 1/2″ racing pumps.

The new racing pumps have shown better top end speed while retaining all the performance values of the original race pumps.

They also come with the new trim nozzle which has been beneficial to race drivers in improving their track times.
