To build the perfect turbocharger you must understand the desires of the customer and understand the dynamics of the engine itself. The 1.6 EcoBoost motor has no better home than Pumaspeed, with 20+ years of experience, race engines being built every week to power levels of over 460bhp you couldn’t be in better hands.


The X57 series of turbochargers has been designed from the ground up with a no-compromise attitude. They feature the very latest spec genuine K04 / K16 Motorsport internals and state-of-the-art billet 7 blade extended tip CNC compressor wheels. The exhaust housing has even been manufactured from one of the most advanced materials, D5B Niresist, which is used on the bomb-proof Garrett turbo range so these truly are high spec units. These turbos have been testing on road and track since late 2018 and have easily proven themselves durable and without compromise on power, reliability, and response.

Fully cast in the UK and hand-finished with all genuine high-grade K04/16 components these custom-made units come fully guaranteed to blow the competition away.

325 whp (370bhp dyno jet) and 430 nm of torque!
Is the new X57 entry model turbo too good for the stock fuel system?
There are many customers asking us for safe maps, in fact, the number one question we have at Pumaspeed is, ‘Can my stock engine handle this power?’, ever happy to answer, we took a decision to build the first in the new V57 map structure around the stock injector flow limits and dial in sensible boost limits and let the power find its own happy level.
The Fiesta ST has weaknesses in the gearbox and various other hardware areas, all these had to be taken into account when mapping, so with almost all MAXD-OUT maps we prefer to keep the torque at around 420nm or 310lb-ft.
Maximum Boost: 1.62 (23psi of boost) (Stock Boost is 1.55)
Maximum Power: 365bhp at 6600rpm
Maximum Torque : 300lb-ft at 4000rpm
Air Fuel Ratio: set at 11.5:1 on stock fuel pump and injectors
All Power Measurements were made on Courtney Sport Dyno Jet dyno on Ford Fiesta 2017 ST200 with less than 20k miles


What’s the next step for this setup?
The simple answer is to add extra fuel, by using the larger set of Bosch injectors. With another 30% more flow, we know the X57 will be able to boost a little higher and add a little more ignition and show its true potential

The X57 was designed to be made is a few different internal sizes to suit various power requirements.
The 3 sizes Pumaspeed have chosen work to give that perfect balance between spool and power depending on how far your fuel system and engine internals will allow you to push.

Please select the unit that most suits your application and hardware already fitted to the vehicle.

To run the power below reliably please ensure your car’s build specification is close to the Pumaspeed Recommendations below.
A fully Forged and Linered Block ( Pumaspeed Blue Top Engine ) is not essential,  415 bhp has been achieved on a totally Stock motor in the UK and 410 whp on USA spec Fiesta ST. However for repeated track and motorsport use above 380bhp ( U.K. bhp rating ) the limits of the stock Rod and Piston combination is very questionable, so we do advise these are swapped for engine longevity.
