After a very successful run with the Turbo Technics S242 revo turbo upgrade, revo has literally taken hybrid turbos to an all new level with their newest offering.
The ultimate Turbo upgrade option for the Fiesta ST, Only Revo completely redesign the entire compressor and turbine housing to give you a driving experience like no other. Exhilarating top end power coupled with the responsive driveability low down means you get best of both worlds.
The limitations of the housings on stock turbos means that they can only be machined to a safe thickness to allow a slightly larger compressor and turbine wheel. The issue with running larger wheels in smaller housings is the increase in temperatures, this is one of the biggest issues with the turbine side of ST hybrid turbos. Increasing both wheels allows for a power increase with higher boost pressures, however, they cannot constantly maintain power due to these increases in temperatures.
The Revo RT330 offers a significant upgrade over the stock KP39 turbo, with completely bespoke castings of both the compressor and turbine housings. Without being limited by the OEM turbo housings, superior flow characteristics are achieved by increasing the wheel size, eliminating heat issues and providing constant high performance. The custom turbine housing has been designed specifically for the Fiesta ST and offers a direct OEM fitment.
Strength is the key, an exclusively designed thrust bearing assembly allows for the higher thrust loading requirements of running increased flowrates and boost pressures without compromising on reliability. The K04 frame upgrade incorporates a larger diameter shaft and bearings, which provides increased strength at high power levels. Integrating the recirculation system with swirl-assisting minimises shaft deceleration on gear changes.
The following testing was carried out on a Ford Fiesta ST running stock engine and fuel system, on Shell Power 99ron Pump fuel. Revo RT330 Turbo Kit, Performance ECU Software installed, fitted with a Revo Air Intake System, Airtec Stage 3 Intercooler and Milltek Turbo back exhaust system with sports Catalytic convertor.
The Revo Turbo offers significant performance gains over any stock turbo setup, with peak gains of up to 158HP and 177NM torque over a stock Fiesta ST, recorded on a Maha Dyno. Compared to the KP38ETR Hybrid setup, the RT330 offers an additional peak gain of 34HP at @ the hubs and 37NM
