Turbo Concepts Exhaust Gas Temperatures

Further comparing the Turbo Concepts Stage 1 turbochargers to the Borg Warner K04’s, the chart below is an illustration of how the exhaust gas temperatures compare.

The pre-turbo temperature is recorded via the car’s Exhaust Gas Temperature sensors which are RS6 units.

Post turbo temperatures are recorded via a temperature probe located at a pre-catalytic converter bung that is also used with a wideband O2 sensor.

Temperature readings at about the same manifold boost pressure are shown below.

With the EGT’s starting slightly higher on the Turbo Concepts turbo’s the higher readings throughout are expected.

Nothing notable jumps out at me from these results, both turbo’s look to perform about the same under the conditions that these readings were made.
