Here is my current Owen Developments Turbo setup compared to how the engine was previously with my VF37 turbo on my 2.1 engine, run with a mix of race fuel (33%) and V-Power.

On Zens dyno it produced 399lbft @ 3550rpm, 354BHP @ 5925rpm with the VF37.



Here is the waste gate duty plot, to show you how much more this turbo could be producing if we could go past the limit of the OEM MAP sensor.
