Turbo Master

Proper waste gate management is vital to achieving maximum potential turbocharger airflow. Each Turbo-Master model is designed to deliver that control and allow your engine to take full advantage of its fuel curve to make maximum power for any given exhaust temperature. Quick and easy to install, these products deliver results!

Model -12 Turbo-Master
The model -12 Turbo-Master is designed for the '94 to '98.5 12-valve Dodge-Cummins. The -12 is also ideally suited for use on the 14cm upgrade Cummins turbine housing. With its wide range of adjustability and smooth waste gate control, the -12 is a perfect companion to typical pump and injector modifications on the 12 valve Cummins. The Turbo-Master is a direct, bolt-on replacement for the factory boost canister and fastens using the same mounting bolts. The -12 is more compact than the factory part taking less of the same space it occupied. Installation involves removing and reinstalling the turbocharger and typically is accomplished in 1-2 hours without special tools or talents. All necessary parts and gaskets are included in the kit. The installation instructions detail making the preliminary boost setting. Boost pressure range of adjustment is 14 - 50 psi.

Model -24 Turbo-Master
The model -24 is designed for the '98.5 - '02 24 valve trucks with manual transmission. It is a direct, bolt-on replacement for the factory boost canister on these engines. Installation involves removing and reinstalling the turbocharger and typically takes 1-2 hours using basic hand tools. No special talents are required. All necessary parts and gaskets are included in the kit. A preliminary boost setting procedure is detailed in the instructions. The -24 range of boost pressure adjustment is 14 - 39 psi. This means that the -24 can be used with an otherwise factory stock engine without setting ECU codes. Simply follow the recommendation for setting the boost limit at 20 psi.

The -24 is perfectly suited to be combined with any of the aftermarket performance-enhancing computer boxes. In our experience, the boost elbow supplied with these control boxes will raise boost pressure to somewhere in the 26-31 psi range. In those cases where the box is set to one of its higher output levels, the boost pressure and airflow created by the boost elbow falls short of being sufficient for the fuel delivery being prescribed. The result is that during a hard pull, the egt will be too high and the driver will be forced to back out of the throttle to prevent running the pyrometer needle beyond a practical limit.

With the Turbo-Master boost control, the boost pressure can be set to a limit of 37-39 psi. This boost increase over that created by the 'boost elbow' is accompanied by a significant increase in airflow through the engine, which results in more pulling power and speed for a given egt limit.

Model -GM Turbo-Master
The model -GM was originally created for the '92 and '93 GM 6.5 with mechanical injection. It is a direct, bolt-on replacement for the factory spring loaded canister. These engines respond nicely to the addition of the Turbo-Master accompanied by a fuel delivery adjustment. Modifications to improve breathing will further enhance performance.

The high compression 6.5 is well matched to the factory turbocharger, which is efficient to 15 psi boost. The -GM is designed with a range of adjustment of 3-17 boost.

Recently, because so many are retrofitting the '94 and '95 model engines with earlier mechanical fuel systems, we made changes in the design of the -GM to make it fit these turbochargers as well. This is the perfect solution to turbocharger control in these applications.

The -GM also works well on the computer controlled '94 and '95 models as a replacement for a failed factory canister / vacuum pump. In these applications, the boost can be set to match the factory 4-6 psi range. We are in the process of developing Turbo-Masters for other Cummins applications as well as for the Ford PS and GM Duramax. We also plan on introducing the model -24 Auto soon. Stand by-we will advise you of their availability.
