Jacob White of High Tech Turbo returns to the Diesel Performance Podcast. In this episode, Jacob explains the pros and cons of big, single turbos. He also describes the differences between the s300 and s400 chargers and apparently how size does matter when it comes to driveability. The turbo-talk also dives into the difference between sea level and high altitude turbo performance, something you may need to consider if you live in the mountains.  To learn more about High Tech Turbo - check out the company's website: www.htturbo.com
