The brand new 2.3 EcoBoost Focus ST has a small but very efficient turbo direct from the factory, iot can make a solid 400bhp on a high specification car. The design brief from Ford wasn't for the stock turbo to make power, it was to make torque and ecconomy. It's very simple to see whilst custom mapping the car that exhaust gas flow is diminishing higher up in the rev range.

There is only one solution for this and that's to increase exhaust gas flow by machining the exhaust housing and adding a turbine shaft plus exhaust wheel with a larger diameter.

ENTER THE NEW 440+vPUMASPEED FOCUS ST MK4 X37 HYBRID TURBO

Top end power is all about exhaust gas flow and ignition values, so what do we do to this new X37?

We follow the tried and tested route by making both sides of the internals of the turbocharger larger, so we add the following:

- X37 custom turbine shaft with 9 blades (not 10) and 4.5mm bigger outer diameter
- Custom machined exhaust housing to accept this larger wheel
- Larger thrust bearing to aid reliability and cope with the added loads inside the unit
- We replace the inlet wheel with a new 7 blade rather than the old 6 blade and we increase the size of the wheel from 
- 46.00mm-59.00mm to a 50.8mm-66.00mm 
- The alloy compressor cover is machined to add extra flow and accept the new larger wheel
