The boost pressure that tuners can achieve with an engine having a compression ratio of around 10:1 can vary based on several factors, including fuel type, tuning, engine design, and the specific goals of the build. However, there are some general guidelines:
1. **Fuel Type**: Higher octane fuels can tolerate more boost without knocking. For example, using premium fuels like E85 or racing fuels allows for higher boost pressures due to their
