Thus, the added complexity of wastegate
, variable valve actuation, and electronic throttle controls in these engines may change the conditions under which an increased volumetric efficiency is observed or remove this effect altogether.
The fixed wastegate
has the benefit of being relatively inexpensive and trouble-free, but also Vis the least efficient.

We wanted something more outdoors friendly, however, so we called upon Troy Downey at Wastegate
Technologies to give the truck a new look.
A one-piece serpentine block furnishes extra strength and rigidity, while a wastegate
turbocharger provides better bottom-end response and less heat rejection.
With the wastegate
turbo, a small turbine housing is used to increase the pressure to the turbine wheel at low exhaust gas flows.
The turbocharger has a wastegate
system that diverts exhaust gas away from the turbine when required.
8 with 74 hp (55 kW) rated output at 2400 rpm features the latest generation of Cummins wastegate
turbocharger specifically sized for the engine to ensure rapid engine response to load demands at all engine speeds.
A new solution has also been implemented for the wastegate
valve (which stops boost pressure rising too steeply at high engine output) based on an electronically controlled electric actuator developed by Continental.
Cracked and blown-out cockpit windows were the subject of several reports, as were cracked Bendix mag housings and distributor blocks, loose horizontal and vertical stabilizer attach bolts and cracked wastegate

The company uses a modular approach for an assortment of all makes, sizes and model engines including wastegate
and variable geometry turbochargers.
