Turbo Exhaust System Design

Some turbo back and header back systems replace stock catalytic converters with others having less flow.

Turbo exhaust system design.

A performance exhaust system is a characterizing element for any internal combustion conveyance. 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. 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. 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. 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. Not to mention the poorly designed exhaust system will cause unwanted turbo lag meaning an unresponsive and unexciting driving experience. N a cars utilize exhaust velocity not backpressure in the collector to aid in scavenging other cylinders during the blowdown process.

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.
