Supertech peformance

Homebred Motorsport Technology.

Located in San Jose, California in the heart of Silicon Valley, Supertech was born from the same fertile ground as many other companies in this area utilizing cutting edge technology to fuel growth.

Beyond the technology, what impresses me most about Supertech has been their transparency & regarding their products and intended use. There's no room for BS when it comes to 20,000$ + engines.
