Turbo Exhaust System Design

As most of you know the design of turbo exhaust systems runs counter to exhaust design for n a vehicles.

Turbo exhaust system design.

Given the installed locations of the turbochargers custom formed exhaust pipes are required to route exhaust from the turbos to the remainder of the exhaust system. This includes the size s just figured that one out from the engine to the final exit type of muffler if any type of material for both the dry and wet side of the system and the. With design we mean the entire system from the engine exit point the turbo outlet in most cases all the way to where the exhaust leaves the boat. A poorly designed exhaust system will affect both boost control and peak power in any case so a larger turbocharger is required in order to compensate for this.

The turbo back or turbo back is the part of the exhaust system from the outlet of a turbocharger to the final vent to open air. This is an example of a twin turbo system fitted to an ls7 engine which increases rear wheel horsepower to 1 000 under full boost. N a cars utilize exhaust velocity not backpressure in the collector to aid in scavenging other cylinders during the blowdown process. Defining the acoustic profile and influencing the powerband exhaust design is a more dynamic science than stringing together a few pipes and tacking on some mufflers.

Fwiw i m an turbocharger development engineer for garrett engine boosting systems. Turbo back systems are generally produced as aftermarket performance systems for cars with turbochargers.
