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.

Background: During a discussion about the effects of exhaust back pressure in the turbine housing, it was suggested that the O2 sensor in the turbine housing could be removed so a pressure sensor could be installed. I thought that was a very good idea. When CC Design made my downpipe, I requested they add a
