Background: Previous posts have discussed measuring turbine inlet pressure on the Shuenk IS48 turbocharger with a 5+5 splitter turbine wheel. To compare the standard IS38 turbine wheel with the 5+5 blade splitter wheel, I removed the turbocharger and swapped the center section back to the IS38 turbine. With the IS38-equipped turbine wheel CHRA installed, I […]

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
