Revo IS38ETR Enhanced Turbo Upgrade
Software not included
The Revo IS38ETR Enhanced Turbo offers exhilarating performance like no other. With over two years of extensive development and global testing, Revo offers a reliable package capable of over 500HP without the need to upgrade engine internals or DSG clutches.
Only Revo Enhanced Turbos are specifically designed to work in harmony with your vehicle and Revo Software. Engineered to directly replace the stock turbo, the Revo IS38ETR is a high-quality upgrade, precision balanced to levels above OEM specification to improve performance and ensure reliability.
A direct replacement for the IHI Turbo found on 2.0 TSI EA888 GEN3 engines, the IS38ETR is an enhanced version of the OEM IS38 housing, providing over 45% more flow capability offering the potential of over 500HP. Revo Hardware and Software are the key to achieving this performance and have been developed to work in harmony with the ETR upgrade.
- Capable of 500HP +
- 45% More Flow Capacity
- Bespoke uprated bearing system
- Enhanced compressor and turbine wheels
- Designed in harmony with Revo Software
The high-performance Revo IS38ETR offers a significant upgrade over the stock IS38 whilst maintaining the original fitment and compressor and turbine housings. The compressor and turbine housings have been CNC re-profiled to match the larger wheels and stronger shaft, also allowing room for a bespoke heatshield matched to the increased internal diameters. Strength is a key factor to the IS38ETR, a replacement back-plate machined from a billet piece offers a greater resistance to warping. The larger bearing housing has also been upgraded to make room for a specifically designed bearing system, incorporating a reinforced thrust bearing. Precision balanced to levels above the OEM specification reduces vibration to the lowest possible level and improves performance and reliability of the turbocharger.
The stronger construction of the compressor wheel, which is machined from solid billet aluminum, features a slimmer nose, hub and back design along with thinner longer blades and tapered tips. This lightweight construction of the compressor wheel ensures low inertia, in turn increasing performance. The 3D image shows both the compressor wheel (larger) with turbine wheel and shaft.
TURBINE WHEEL AND SHAFT
The precisely engineered turbine wheel and shaft provide sufficient power to the compressor, converting the engine exhaust gas into mechanical energy to drive the compressor, without the need to cut back blades or compromise efficiency. Incorporating a larger diameter shaft provides increased strength and durability at high power levels.
INTEGRATED RECIRCULATION SYSTEM
The integrated recirculation valve is fundamentally a blow-off valve integrated into the compressor housing. When the throttle valve is closed and the pressure in the inlet drops, the valve opens and air from the discharge side of the compressor is diverted back into the inlet of the compressor. This helps to avoid the compressor going into surge.
TURBO MUFFLER DELETE
The Revo Turbo Muffler Delete offers a high-quality single piece replacement for the OEM part which allows for smoother uninterrupted air flow, increasing throttle response and providing improved turbo acoustics. Its single-piece design allows air a more direct path when exiting the turbo, smoothing flow to offer enhanced throttle and boost response. This part comes complete with a high-temperature gasket to ensure a secure seal when installed.
The following testing was carried out on a VW Golf MK7 R running stock engine and fuel system, on Shell Power 99ron Pump fuel. Revo Stage 3 ECU & DSG Software installed, fitted with a Revo Carbon Series Air Intake System, Revo Intercooler, Revo Intercooler Pipe Upgrade kit and a 200-cell sports cat downpipe and exhaust
The Revo IS38ETR offers significant performance gains over any stock turbo setup, with peak gains of 171HP at the hub and 185NM torque over a stock IS38 VW Golf R. That’s over 450HP at the hubs and maximum increases of 173HP @6500rpm and 215NM @2800RPM, all recorded on a Dynapack Hub Dyno. However, over the two years of global development, numerous vehicles have been run on various dyno types, running between 470 to 520BHP, depending on dyno setup, hardware and fuel quality.
