Brian Tooley Racing (BTR) – the story
Brian Tooley has been in the performance racing game for nearly three decades.
Starting his own business back in 1992 called Total Engine Flow, Brian was using a Flowdata flow bench. Shifting to Holley Performance Products shortly afterwards, he helped develop the SysteMax head, intake and camshaft packages.
Going back to working on his own in 1996 until 2004, Tooley then built Total Engine Airflow into an industry titan.
Since then he sold his business to Summit Racing Equipment and stayed on until 2010 when he decided to be closer to family and friends.
As his BTR webpage revealed, it wasn’t long before Brian was back after seeing a need for quality spring kits at affordable prices.
