The Focus Mk4 1.5t engine is almost identical to the Fiesta ST Mk8, as we have developed the Hybrid turbo for the fiesta ST it made sense to carry that over into the Focus Mk4 1.5.
The X37 unit is a very sensible Hybrid that builds on the stock unit and still has very quick spool specifically for road use. The X37 hybrid turbocharger to suit the Mk8 Fiesta ST 1.5T was dyno proven to make 295-300bhp and 410nm torque so with the correct mapping the Focus can benefit too.
The original X37 hybrid on the Mk7 ST was a true 300bhp unit and without doubt ruled the power game with a sub 13 second drag run. On the road, the turbo delivered a beautifully driveable torque curve, delivering the power progressivley through the rev-range, preventing early wheelspin, and letting the driver really enjoy the performance potential of the ST spec.
This new X37 hybrid turbocharger to suit the 3 cylinder 1.5 engine found in the Mk8 ST and Puma ST has pedigree in its blood and a lot to live up to, and we know it's done it! Down to the specifics then... to achieve 305bhp the X37 needed to allow the 1.5T dragon engine to breathe fully. Adding more exhaust gas flow is the key to increaseing power.
The more exhaust gas you allow to escape, the more power will follow. On the X37 therefore we have engineered the use for motorsport spec cut-back turbine blades to allow the gas to escape, meaning a higher flow at higher RPM. With this half of the turbo sorted, we moved onto the "cold side" where we have fitted our unique 7 blade extended tip design CNC compressor wheel.
Having seven blades with extended tips over the standard six blades, more air can be 'grabbed' and passed down through the hot side pipes and eventually into the engine.
This extra air is mixed with the petrol and ignited into bigger boom, thus more power! Internally, the core of the turbo is fitted with a modified seal plate to match the high-flow compressor wheel, and a heavy duty thrust bearing to allow for more lubrication and therefore more longevity than the genuine Ford core.
