“My Miata build has been non-stop since I purchased it in 2017. Initially, I just wanted a track toy with less expensive consumables than my Mustang GT, and this ticked that box. After a while, I just wasnโ€™t getting any quicker and knew I wanted more power. After a lot of research, I chose the Track Dog Racing Rotrex supercharger kit (highly recommended). After some setbacks, the car is now at the top of its game. Iโ€™ve managed to put down laps at The FIRM in the 1:15s, and 1:14s look to be a real possibility in cooler weather. At Sebring, 2:25s are within reach.

In the future, I hope to add a full cage and then a built transmission with custom gearing and a 3.9 final drive. With those additions, I may be able to call it โ€˜doneโ€™.”

Sharing is caring!
