PPE 45/40 Compound Twin Turbo Kit for GM Duramax 6.6L LBZ & LMM
The key is how the strengths of the Garrett GTX4508R and GT4094R are linked and then how both turbos work together at all times. Both turbos are made by Garrett and are oil and water cooled (just like the OEM turbo charger) and ball bearing to ensure they provide unparalleled reliability as well as drivability. Each turbo has their own specialties and do their jobs very efficiently. The GT4094R spools up quicker resulting in an excellent low to midrange power, but once the engine hits mid-range and above the TiAL Wastegate diverts more of the exhaust pressure to the GTX4508R. It is the GTX4508R which supplies the mid to high-end power that will really put your duramax into overdrive. PPE combines the turbos with a custom 3 inch intake bridge and features a 4 inch crossover tube and Race High Flow Exhaust Manifolds with Up-Pipes. This combination provides the engine with drastically enhanced intake and exhaust actions which create an unrestricted flow for the dual turbo system. Speaking of flow, the PPE High Performance Intercooler cools the air before it is pumped into the engine via the 3 inch aluminum boost tubes. The result is a virtually seamless delivery of power that works especially well with PPE's electronic and fuel upgrades. The PPE compound turbo system does all that and still retains its A/C and heater functionality. This way, you can even be comfortable while smoking the competition!
