B8/B8.5 S4 & S5 DOUBLE PULLEY KIT OVERVIEW
This Audi S4 & S5 Power Kit offers a complete all-inclusive power upgrade by combining IE's top of the line performance hardware with the matching IE motorsport-inspired engine and transmission tunes. You will enjoy track-ready performance while retaining factory comfort and reliability. At the core of this kit is the IE Powerlink cable, providing an easy interface to upload your new tunes and maximize the performance of your 3.0T engine. To take full advantage of the supercharger, boost is increased with a smaller diameter supercharger pulley and larger diameter crank pulley. These modifications combine and release the true monster hidden in your bay.
INCLUDES MULTIPLE OCTANES
IE's Double Pulley Tune is Available in 91, 93, 100, and 104 octanes along with a specialty E40 (pump plus E85 mixed) blend. A heat exchanger is required for this modification. If you intend to use the E40 blend, a high-pressure fuel pump upgrade is also required.
E40 ETHANOL FUEL BLEND (DUAL PULLEY & ABOVE)
The IE Stage 2 Dual Pulley Tune offers you tons of power potential on multiple octanes options including support for E40. The S4 B8/B8.5 factory fuel system cannot safely support the amount of fuel needed for full E85 even with an HPFP upgrade, however, it can support a maximum blend of ethanol to E40. E40 is an ethanol mix of E85 with regular pump 91/93 fuel (about 2/5ths E85 and 3/5ths 91/93 with E10 premium gas). To run this fuel safely, it must be pre-mixed and verified before filling into an empty tank. You can read our blog article on how to safely blend ethanol HERE.
EXTENDED RPM RANGE
The Audi 3.0T engine continues to make power beyond the factory rev limiter, especially when pullies are added. Our tune files allow the engine to access all of that power by increasing the rev limiter.
Stage 1 RPM limit: 7200 RPM*
Stage 2 single & dual pulley limit: 7350 RPM*
*DSG Calibration will shift slightly before these cutoffs
INCLUDED IN KIT
IE Dual Pulley Tune
Ready to unleash serious power? IE's Stage 2 Double Pulley ECU calibration is for owners running both the smaller supercharger charger pulley along with an additional larger crank pulley. These two pulley's combined create the optimal supercharger ratio resulting in up to 534HP and 520TQ!
IE DSG Transmission Tune
A great deal of sportiness is added to the tune while maintaining factory smoothness and driveability that you love about the S4. More aggressive launches and faster shifts are guaranteed to put a smile on your face. Also, expect acceleration and 0-60 times to improve dramatically from a larger useable powerband provided by the higher shift points. The purchase of an IE DSG file grants you access to customization of launch points. With several launch points to choose from you can pick what works best for your setup!
Available Launch Control RPMs:
- 3400 RPM
- 3600 RPM
- 3800 RPM
- 4000 RPM
IE Supercharger Pulley Upgrade
The pulley functions by increasing the supercharger RPM throughout the full powerband. At redline supercharger speed is increased by 1800 RPM. The IE pulley is 57.50mm in diameter, making it one of most aggressive and powerful on the market
IE Crank Pulley Upgrade
The IE Overdrive Crank Pulley Upgrade is designed to work in-hand with the IE Overdrive Superchager Pulley Upgrade Kit. When installed together the charger speed will increase by 26% resulting in higher boost levels and more power. Also required for proper operation is a stage 3 tune and intercooler upgrade. Healthy power gains will be realized from running a dual pulley setup, however, gains will vary depending on the ECU tune used. This pulley also removes all supercharger torque from the OEM Damper unit, greatly decreasing the chances of damper failure.
