Tuning the ST 225 Focus just got serious.
The new X-48 420bhp plus Hybrid Turbo has arrived with the capability to push over the 400 bhp mark every single time.

X37-400 vs X48-420
The older X37 Hybrid had a 12 blade Turbine Wheel so had 12 blades to promote quick spool, the New X48 has 9 blades so allows more gas to pass in between the blade to allow more power
The older X37 had a 7 Blade compressor Wheel, the New X48 has 1 more blade and is a larger diameter.

The New Pumaspeed X-37 400 Stage 2 Hybrid for the ST225 Focus has a unique turbine shaft and Billet 7 blade compressor wheel that can power over the 400 bhp mark. Far superior to any other small frame K04/K16  Hybrid available.
The same internals inside Golf R units has powered well over 420bhp!


For many years the Focus RS mk2 turbocharger has been the logical next level of tuning for the Focus ST225 owner, the Focus RS Mk2 K16 turbo was virtually a direct fitment with the addition of some simple water and oil pipework. But now that has all changed.
The bespoke manufacture of a new design turbine shaft and wheel has allowed the exhaust side of the turbo to be enlarged from 50mm in the stock st225 to 54.1mm which is virtually identical to the Focus RS Mk2. So you have all the flow and power from the RS Mk2 but inside the small frame housing and stock pipework.  Far less cost far better spool and 390-400 bhp.

The New X-37 400 bhp 7 Blade Hybrid Turbo is unlike no other,  Built to outperform all the competition with a huge Focus RS Mk2 Exhaust wheel and full 7 Blade CNC Billet Compressor wheel it has proven time and time again that 400 bhp is a genuine possibility for any Focus ST225 owner.
