PJR was established in 1984 in Worcester Park Surrey, initially rebuilding Weslake push rod and SOHC Godden engines. Our first experience in World Championship speedway was in 1985 preparing GM engines for Kelvin Tatum, for his first world final. In 1986 we did the same for Marvyn Cox's maiden world final. In 1990 Per Jonsson won the World Final in Bradford (although we got no credit for it!)  In 1996 we prepared the GM engines Jason Crump used to win his first GP.

We moved to our current site inWarwickshire in 1996.

In 2003 our Schenck engine dynamometer was installed.

In 2013 we took delivery of our Hurco 5 axis machining

centre.

We built all the GM engines that were used to win the

2012, 2013, 2014, 2015 & 2016 Speedway World

Championship GP series. We also supplied the runner up

in 2014, 2015 & 2016.

To date we have built the engines that have been used to win 38 SGP rounds
