If you're familiar with the diesel performance industry, you know that not all turbos are built equal. Some are designed for the street, others for towing, and then there are the ones built for the track. We offer a wide range of turbos, but Tha Donk is one of our most popular options. Now, let's talk about why…

As the largest single S400 turbocharger in the Stainless Diesel lineup, THA DONK isn't just a turbo, it’s a statement piece. Designed for high boost competition setups, nitrous monsters, and high horsepower diesel builds, this turbo delivers massive airflow with the distinctive, aggressive whistle that only our 5Blade Mafia wheel technology can produce.

What Makes THA DONK a Different Animal?

Building a high horsepower single turbo setup requires balancing massive airflow at the compressor with enough exhaust flow on the hot side to prevent destructive backpressure. Here is how THA DONK handles business under high load:

• 95mm Billet 5 Blade Compressor Wheel: Our signature 5 blade design moves unmatched volumes of air while drastically improving spool up time over traditional wheel designs.

• The "G" 4" Turbine Wheel: This is the absolute largest turbine wheel that fits into the S400 footprint. It provides the exhaust flow needed to support big horsepower without choking your engine.

• T-6 1.32 A/R Exhaust Housing: Engineered specifically for top tier flow rate and maximum exhaust energy delivery under heavy boost.

• .71 A/R Race Cover & 5" High-Flow Inlet Bell: The high flow bell feeds smooth air straight into the cover, minimizing lag and keeping air velocity high all the way up to max boost.

Key Performance & Setup Specifications

Important Performance & Tuning Notes

Because THA DONK moves so much volume, it requires a setup built to handle extreme flow:

1. Requires Full Flow (T-6 Only): Do not attempt to run THA DONK with a choked down 1.15 A/R housing. This turbo demands a maximum flow exhaust setup to run safely and efficiently.

2. Wastegate Recommendations: If you plan on spraying nitrous, running an external 45mm–50mm wastegate is strongly recommended to regulate drive pressure and protect your engine components.

3. Respect the Boost: Capable of pushing upwards of 80 PSI, this turbocharger can easily push stock engine components past their limits. Ensure your bottom end and head studs are ready for serious cylinder pressure.
