The dyno results below shows the stock VF37 turbo against our own spec Mitsubishi twin scroll TD06 turbo and a Garrett GT3071 ball bearing twin scroll bolt-on kit. The dips in the graph are due to the variable cam timing on this engine.
Note: our turbo is journal bearing, yet it still out performs the Garrett ball bearing turbo and at a fraction of the cost. With more time to fine tune, we expect even better results. This test was done on pump gas 18lbs boost.
