    Weistec Twin Turbo System Gen 2 Audi R8

  • Advertised gains are estimates of HP and Torque “at the engine” calculated from gains as measured on a Dynojet Dynamometer in ideal conditions and typically show the largest possible change.  Actual gains are dependent on the following: Learn More about Crank HP Vs Wheel HP

    Model – Manufacturers use the same engine in multiple model vehicles and often times they are in a different state of tune, for example: 2008 C63 and a 2008 CLK Black Series.  Both have the same engine, but the C63 has 451hp while the CLK63 has 500hp.  Naturally the C63 will show more gains as it starts at a lower level.

    Model Year – Similar to above, as time progresses, Manufacturers tend to slightly increase power output via software from one year to the next or offer “Performance Packages” with increased power.  The engines remain largely unaltered and as a result, final tuned output remains the same, while the gains are lower as the starting point is now higher.

    Fuel – Fuel quality is HIGHLY important with performance vehicles.  Low quality and/or low octane fuel will greatly impact engine output and potentially even engine health.  Top tier brand premium fuels should always be used to achieve the best results possible.

    Drivetrain – All wheel drive has higher drivetrain losses than rear wheel drive.  This results in lower numbers when testing on a chassis dyno.  Wheel/tire size and weight will also impact chassis dyno results

    Weather/Conditions – Temperature, humidity, altitude, and air density all impact engine performance.  Heat, high humidity, and thin air will all work towards reducing engine output

    Engine Health – Higher miles tends to result in increased build up and lower compression which can and will impact engine output.  Properly maintained engines will have better performance than abused or neglected engines.

    Supporting modifications – The highest power levels require supporting modifications.  Depending on the engine, this could mean forged internals, built transmission, upgraded fuel system, 110+ octane race fuel, etc.

Product Description

* Allow 2-4 weeks for orders to be shipped. Turbochargers are made to order.

The Weistec Twin Turbo Kit for the 2nd generation Audi R8 is designed and manufactured for those that want to have a well thought out, quality kit installed by their local preferred shop in less than a week. The complete kit includes all major components and hardware to allow for quick and straight forward installation by an experienced and qualified shop. As designed, the kit does not require engine/transmission/fueling upgrades but it certainly has room to grow well beyond the ~900HP it makes with the included ECU tuning for minimum 91 octane gasoline. Should you choose to upgrade the engine/transmission/fuel system at a later date, the turbos can support up to 1600hp, so those that eventually want more power can get it.

Twin Turbo

Maximum Performance

The Precision PT6266 Gen 2 turbos effortlessly make ~900HP at 7psi in this application. The standard boost level makes for good performance and consistency on California 91 octane fuel. Those that want more can certainly get more with higher octane fuel and further supporting upgrades.

Quality And Finish

All exhaust components are tig welded 304 stainless steel construction and flanges are CNC machined to ensure best quality. After welding, exhaust plumbing is brushed for a clean finished look.

Turbo Pipe Inspection

Heat Shield


Turbo blankets are included to keep heat in the turbine housings for better turbo response and to help reduce radiant heating of other components. A large heat shield is also included to protect the bumper from hot exhaust piping.


The Twin Turbo Kit features an intercooler system designed to be as effective as possible without requiring body or chassis modifications. All the coolant lines for the intercoolers are -12AN sized stainless braided lines that are also shielded. Each intercooler has its own side mounted heat exchanger with an aluminum shroud featuring dual Spal fans. The fans ensure that there is always good airflow across the heat exchangers to help keep intake air temperatures under control. The intercooler recovery tank bolts in behind the engine oil tank and has an integrated stainless steel heat shield to protect against radiant heat from the downpipes
