Background: The CC Design downpipe I use was custom-built with an O2 bung a couple of inches downstream of the turbocharger turbine housing. The intent was to allow measurement of the exhaust gas temperature (EGT) as it exits the turbine housing and to measure backpressure in the exhaust system. Setup: To measure EGTs, I installed […]

Background: As discussed in the last post, an exhaust measurement system was installed in the IS48 turbocharger to measure the turbine inlet pressure. During the first test, the exhaust was catless. For the next test, a GESi catalytic converter was added to the exhaust system to assess the effect of the high-flow cat on turbine

Background: A previous post discussed installing equipment to measure exhaust backpressure upstream of the turbine inlet. With the measurement equipment installed I took the GTI for a test drive to record pressure levels in the turbine housing upstream of the turbine wheel, what is referred to as the Turbine Inlet Pressure in the charts below.
