D-Max Type-R update: 09/30/05
Exhaust Manifold Design and Production
There have been many small tasks performed on the Type-R lately as the Banks Race Shop crew thrashes to finish the truck. The list of tasks being tackled is as long as your arm. Some of the details are shown below.
Banks’ Chief Designer, Bob Robe is shown measuring D-Max Type-R exhaust manifolds. Robe designed and fabricated the exhaust manifolds from 321 stainless steel, which is a high grade of stainless that can handle elevated temperatures longer than other grades of stainless. During a 25-hour race, there is a strong possibility of cracks occurring. Robe considers exhaust manifolds “expendable” and will have several sets available.

Twin-Turbocharged Duramax Engine Development
Testing of Banks’ twin-turbocharged Duramax racing engine program is well underway. Banks has run the test engine in various states as shown. First, the stock Duramax engine was run and horsepower and torque numbers were baselined. Next, the engine was run controlled by Banks electronics with exceptional results. After this data was logged, Banks twin-turbochargers and Big Hoss intake manifolds were installed and run. See above.
Shown is a 2006 GM Duramax LLY V-8 turbodiesel undergoing testing in one of Banks dynamometer cells. After horsepower and torque numbers were baselined and recorded, Banks installed its electronics and recorded the horsepower and torque gains.

It took an incredible amount of stainless-steel tubing to plumb Banks new twin-turbocharged Duramax LLY V-8. Over 75 hours of dynamometer time has been logged on Banks Duramax racing engine program so far.
