94-02 Dodge Ram 5.9L Cummins PDD HX Super 9 Turbo Kit Bundle (550 - 800HP)

This is the HX super 9 with an HX40 flange turbo kit. It is the highest horsepower capacity, quickest spooling turbo that still uses a t3 turbine inlet foot. On our chassis dyno, this kit made more torque per rpm with the 60mm compressor wheel than the k27 turbo, which is rated to 400whp.

The turbine outlet has been modified to fit HX40 downpipes. We use the HX40 as the standard because it is popular, easy to get for the end user, fits, and is the lowest cost pre made downpipe.

PDD 60mm billet compressor wheel supports 550whp Great Towing turbo

PDD 62mm compressor wheel supports 650whp 10k or less towing

PDD 67mm compressor wheel supports 800whp not recommended for towing

These numbers are plus or minus 50whp.

We have learned how critical it is to select the proper sized compressor wheel for your application. The 60mm is the best for tow/600whp trucks. It is an absolute monster of a turbo at 50 psi on a 5.9L motor. We rate the compressor to 3500 rpms. The 62mm is a good compromise for tow/hp capacity and a rpm bump to 3700rpms at 50 psi. It does lose some torque in the low to mid vs the 60mm compressor, but when a little more running room is needed rpm-wise and/or capacity, it is a great choice.

The big bad 67mm max-effort compressor wheel has most surface area, has the highest blade loading, and as such is the slowest spooling unit. It is still faster spooling then the 62/68/.70 sxe turbo. Just slower then our 60mm and 62mm compressors. With a whp capacity of 800whp and 4000 rpms at 50 psi, it is an absolute monster with the widest rev range out of the three compressor sizes. We usually use this turbo for 600whp verified minimum motors to properly drive this monster.

The 67mm turbine wheel can support up to a sustained 60 psi (we do test to much higher pressures then 50 psi, we have pushed upwards of 76 psi gauge verified, but for longevity and reliability we recommend 50 psi). We only use the 67mm turbine wheel on all of our turbo chargers due to thorough testing on both the dyno and in competition. This wheel produces the most power, best response, and best egt control out of all the turbine wheels and turbos we have tried.

This kit also comes with our spring gate to net the boost pressure. That being said your own boost pressure will vary based on fueling, tuning, and elevation. If you’re unsure of what’s safe, we recommend a maximum of 50 psi/4000 rpms for reliability. We run our turbos and products in competition on a 13mm p7100 powered pull truck that we compete with, as well as other heavy haul and high powered street rigs. We believe in what we sell.

Current lead times may be 1-3 weeks. These things have taken off like crazy and we work as hard as two guys can to get each order big or small taken care of to our standard of hand crafted parts and components. We care about all of our customers and products to a extreme degree.
