APS TSR 70 TWIN SCROLL ROTATED MOUNT

APS has designed and produced what is arguably the ultimate in bullet proof extreme flow Twin Scroll turbochargers for the Subaru Impreza enthusiast.

Unencumbered by the limitations of current off the shelf WRX turbochargers, APS has totally engineered a "no-compromise" turbocharger from the ground up to match the exact requirements of extreme performance Subaru Impreza engines.

APS has utilized extreme flow Ball Bearing Turbochargers, rotated to avoid the restrictive standard intake duct, in its race cars for many years.
The twin scroll design of the APS TSR turbocharger permits separate exhaust gas pulses from each cylinder firing order pair to effectively drive the turbocharger's turbine with the maximum exhaust gas energy possible. This results in quicker turbocharger response and higher horsepower than an equivalent non-twin scroll design.

The APS TSR turbocharger incorporates innovative anti surge ports that effectively broaden the turbocharger compressor's operating range particularly near the surge line of the compressor map. At the surge point, compressed air is permitted to pass through the compressor wheel and into the anti-surge slot and ports, thus drastically reducing compressor surge.
Unlike turbochargers designed to suit the stock position and orientation, APS TSR Series turbochargers are supplied as a comprehensive and complete bolt-on system.

To coincide with the release of the APS TSR70 turbocharger system, APS has designed the ultimate Twin Scroll up-pipe that delivers a double blast of separate exhaust gas pulses to the turbocharger. The true twin scroll design completely eliminates the mixing of exhaust gasses from each of the cylinder firing order pairs. This delivers a huge amount of energy (hence horsepower). In addition, the APS up-pipe included with the APS TSR 70 turbocharger system incorporates a remote wastegate connection. TiAL 44mm Wastegate Included.

Why Twin Ball Bearing??

Demands for improving acceleration response and for the reduction of so-called turbo lag are popular amongst performance enthusiasts who wish to take advantage of the enormous gains in power and torque delivered by turbochargers. In addition, bullet-proof reliability is required particularly at high turbocharger boost pressure levels as well as at extreme exhaust gas temperatures commonly found in high performance turbocharged engines.

In order to achieve crisp turbocharger response, a number of advances in turbocharger design have been utilized over the past decade. Primarily through the use of modern metals/ceramics in order to reduce the mass of the rotating assembly. However, significant gains have been made by reducing the friction of the rotating assembly - and this has meant a departure from traditional turbocharger designs.

Traditional turbocharger design employs a conventional plain bearing that runs on a film of oil. This is known as a floating metal bush.

APS turbocharger rotating group above is a true twin ball bearing unit that not only delivers huge power and torque, but is also extremely robust and incredibly compact in size.

APS Equal Length Header

Header design is a very precise and complex process that demands the highest levels of engineering and a thorough understanding of the STI engine if the optimum header is desired.

APS has designed and manufactured what is arguably the ultimate STI header system on the planet. Designed specifically for high-powered STI engines, the APS Equal Length Split Pulse Header system delivers an outstanding improvement in power and torque, particularly in the mid RPM range.

By dissipating the hot exhaust gasses more efficiently, the APS High Energy Header System lowers the thermal load on vital engine components such as pistons, combustion chambers, valves etc., particularly at high horsepower levels.

Careful attention to detail in key areas is critical in order to deliver the highest possible performance and maximum component durability. From smooth flowing Y couplings through to internally and externally precision TIG welds where tubes meet flanges, APS' high attention to detail ensures the optimum results and powerful operation.

All flanges are internally and externally precision TIG welded to ensure smooth flow and the highest possible component durability.

For extreme horsepower applications where individual EGT sensors are required APS now supplies the APS Equal Length Split Pulse Headers with threaded sensor bosses right up near the manifold flange - One sensor for each exhaust port - for perfect performance.

Smooth flowing Y couplings result in smooth flowing exhaust gasses and the maximum performance possible.

The stock plastic splash/aero tray is retained to deliver un-compromised protection and under-hood airflow dynamics

The comprehensive APS High Energy Header system includes all mounting hardware, stud, and nuts for easy installation.

APS recommends that the APS High Energy header system be wrapped with robust heat shielding in order to minimize exhaust heat loss and heat transfer to the engine bay.

any proven results from this set up?

Yes. I'll poke around for some graphs, but for those that are willing to pay the pretty penny for the APS name... this is one of the most sought after kits out there.

PS> As far as I know, these are the ONLY APS header in the country right now.
