“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 wasn’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. I’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 ‘done’.”

Sharing is caring!
