Exhaust Manifold with Turbine Housing

By popular request, BorgWarner K04 turbine housing attached to the stock and AWE exhaust manifold on the flowbench.

This is a follow-on to the exhaust manifold flow test of the AWE tubular manifolds and stock manifolds.

AWE Exhaust Manifold attached to K04
AWE Exhaust Manifold attached to K04
Stock Exhaust Manifold with K04 turbo attached
Stock Exhaust Manifold with K04 turbo attached

Results, along with results of just the K04 turbine housing without any exhaust manifold.

Not too surprising, but not much to take away from this chart either, other than the fact that the turbine housing is a significant flow restriction, which makes sense given what the part does.
