Introducing the all-new 8391, 8691, and 8891 Next Gen Pro Mod turbochargers from the world leader in turbocharging technology. This expansion of our Next Gen turbocharger lineup fills the gap between our largest Sportsman turbochargers and our Next Gen XPR Pro Mod turbos — providing a huge upgrade for customers who want to step up their projects and need more airflow without moving all the way up to a 103mm turbine wheel. This lineup carries forward a winning legacy that has powered racers to low 7-second and high 6-second passes in 4-, 6-, and 8-cylinder applications. With new 83mm and 86mm options added to the range, racers can now tailor performance to their specific combination and goals. Each turbo incorporates an advanced 7x7 CEA® compressor wheel, delivering enhanced strength and optimized airflow. In testing, these units surpassed our previous Gen 2 models across all configurations. It’s time to go 6s!
