Turbo Engine Exhaust System

So intercooler are then used to cool the intake air to the engine from a turbo system.

Turbo engine exhaust system.

The compressor pressurizes the air going into the pistons. Tuning an exhaust system to a given application is a case by case basis challenge. The final step was to install the 4 0 inch race exhaust which pushed the power output to an even 919 9 horsepower at the same 6 400 rpm while peak torque rose to 807 lb ft of torque at 5 500 rpm. N a cars utilize exhaust velocity not backpressure in the collector to aid in scavenging other cylinders during the blowdown process.

Exhaust backpressure on turbo engines is one of the most misunderstood aspects in tuning to many people but it s pretty simple it s not good. The exhaust from the cylinders spins the turbine which works like a gas turbine engine. General rules of thumb are easy to grasp but applying them correctly is where things get tricky. On non turbo engines backpressure is a single issue the pressure in the exhaust system but on a turbo engine it s actually two issues pressure in the post turbo exhaust system and pre turbine backpressure in the exhaust manifold.

The exhaust system is a crucial part of any vehicle. Fwiw i m an turbocharger development engineer for garrett engine boosting systems. The post turbo back pressure dropped from 1 9 psi with the 3 0 inch exhaust to just 0 9 psi with the 3 5 inch system. An exhaust system is usually piping used to guide reaction exhaust gases away from a controlled combustion inside an engine or stove the entire system conveys burnt gases from the engine and includes one or more exhaust pipes depending on the overall system design the exhaust gas may flow through one or more of.

As most of you know the design of turbo exhaust systems runs counter to exhaust design for n a vehicles. An alternative placement for a turbocharger is to have it rear mounted as part of the exhaust system. 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. Many cars manufactured after 2005 might need a tune up or an upgrade of the exhaust system.

The displacement exhaust valve size induction system cam profile exhaust port design and rpm range all factor into deciding what form the exhaust system should take. The turbocharger is bolted to the exhaust manifold of the engine. One of the biggest challenges car owners and enthusiasts face is increasing their engine s performance. The turbine is connected by a shaft to the compressor which is located between the air filter and the intake manifold.
