APR TTE625/TTE700 Adapter Ring
Los anillos de adaptador entrelazados forman una entrada ideal coincidente con portuaria al turbocompresor, mientras que los anillos más grandes (vendidos por separado) proporcionan soporte coincidente para actualizaciones de turbocompresores híbridos aún más grandes. Diseñado para usar con el turbocompresor TTE625 y Tte700.
El Sistema de Entrada del Turbo APR supera en flujo a los componentes de fábrica hasta en un 45%, y aumenta hasta un 60% al agregar el Filtro de Entrada APR. Esto se logra en primer lugar mediante la eliminación de la restricción más crítica en todo el sistema de admisión, el tubo de entrada del turbo. Debido a esta restricción, ningún diseño de caja de aire / filtro de admisión puede igualar físicamente las ganancias obtenidas al actualizar solo al Sistema de Entrada del Turbo APR. Esta entrada es el primer paso que se debe tomar al mejorar el sistema de admisión y allana el camino para obtener aún más ganancias al agregar el filtro de admisión opcional.
El sistema de entrada del turbocompresor APR utiliza un enorme tubo de entrada de fibra de carbono de 4" que se conecta a la caja de aire de fábrica o al sistema de filtro de admisión APR. Adjunto al tubo de fibra de carbono hay una entrada de aluminio fundido de 4" que tiene una forma orgánica para retener el área transversal más grande posible dentro de la tubería hasta la entrada de la cubierta del compresor del turbocompresor. A pesar de la forma visualmente extraña, mantener el área transversal lo más grande posible es la clave para obtener ganancias de rendimiento en la tubería y supera con creces los diseños de forma continua y suavemente cónicos.
Los anillos adaptadores entrelazados forman una entrada ideal con coincidencia de puertos al turbocompresor, mientras que los anillos más grandes (se venden por separado) brindan soporte con coincidencia de puertos para actualizaciones de turbocompresor híbrido aún más grandes. Un protector térmico de acero inoxidable grueso protege la tubería del colector caliente del turbocompresor, y una tubería externa de PCV de acero inoxidable proporciona una colocación adecuada del PCV sin afectar el diseño de la entrada.
Finalmente, agregar el Filtro de Admisión APR opcional transforma por completo el sistema de sutil a extremo. Nuestro masivo filtro de algodón de 9" de largo con apertura frontal se conecta a un tubo de entrada de fibra de carbono de 6" que gradualmente se estrecha hasta el tubo trasero de 4". Escucharás cada onza de la enorme demanda de flujo de aire del sistema de turboalimentación de 5 cilindros, y lo harás con una mejora del 60% en el CFM en comparación con el original. Esto solo fue posible con un sistema de filtro abierto, ya que las demandas de flujo de aire requerían un diseño sin caja. En pocas palabras, este es el mejor sistema de admisión en el mercado para satisfacer los requisitos de flujo de aire exigentes sin compromisos.
APR Turbo Inlet System with APR Intake Filter System
APR Turbo Inlet System
The Inlet Restriction
The factory cast inlet pipe is small. It has a maximum internal diameter of 2.8”, at the widest point, and is internally restricted as illustrated in the photos. This pipe is only capable of achieving a maximum of 490 CFM at 28” of H2O when tested alone. Attaching any intake system to this pipe will only result in a lower flow rate, and when using the factory back pipe, airbox, filter and inlet scoop, airflow drops below 430 CFM.
The APR Solution
Our cast inlet pipe is huge and on its own it achieves a staggering 710 CFM with the stock turbocharger adaptor! This is a 45% improvement over the factory part. When paired with the APR Intake Filter System, airflow only drops to 690 CFM, a 60% improvement over the entire stock intake system! When attached to the factory airbox, filter and frontal scoop, airflow drops to 575 CFM, which is 34% better than the stock system and 17% better than the stock inlet by itself with an ideal entrance. This further clarifies the point that no intake can outperform the APR turbo inlet if the factory turbo inlet is left intact.
APR’s engineers tested a multitude of other turbocharger inlet designs in pursuit of more flow and power. It was quickly determined the part could not act as an upgrade on its own because of the significant increase in diameter required. The rear inlet pipe also had to be upgraded to utilize this larger diameter. Other designs, which may look smoother, and offer a continuously reducing taper, are extremely limited. At 3.5”, 550 CFM is achievable. At 4” 560 is achievable. In contrast, our system achieves 710 CFM under the same test. Given how restrictive these other designs are, upgrading to our system, while still using the factory airbox, filter and frontal scoop, will outflow any intake system!
Dyno Testing
The APR Inlet System greatly outflows the factory inlet system, and for this reason, APR’s engineers have created a Stage 1+ ECU to take full advantage of the upgrade. While Stage 1+ is designed for use with an intercooler system, we tested the upgrade with the factory intercooler system to illustrate the gain from the inlet alone. In doing so, the APR Inlet system gained as much as 14 WHP and 11 WFT-LBS of Torque! When adding the APR Intake Filter to this setup, gains grow even further towards redline, adding up to a gain of 32 WHP and 24 WFT-LBS of Torque! When the inlet alone is combined with the APR Intercooler system gains grew further to 37 WHP and 29 WFT-LBS. Gains will continue to grow as higher demands are put on the system via higher stages of performance.

Further Data
APR’s Engineers fully instrumented the engine with pressure sensors and thermocouples (fast response temperature sensors) to further illustrate the affects this product has on the system as a whole. In the simplest terms, this upgrade allows the turbocharger to operate at a lower pressure ratio, which means it will operate more efficiently. It reduces the restriction on the inlet of the turbocharger, allowing the inlet to see closer to ambient pressure conditions. This directly translates to lower pre-turbine backpressure (EMAP), lower turbocharger shaft speed, lower turbocharger compressor discharge temperature, and for the ability to achieve higher boost pressure levels.
The following data was collected with ambient conditions sitting around 985 mbar, 29.4C with 66% relative humidity. The vehicle was setup as Stage 1 (93) with stock hardware, vs Stage 1+ (93) with the APR Inlet. The depression at the inlet decreased by 112 mbar, emap decreased 360 mbar, compressor discharge temperature dropped 14c and the engine was able to achieve 106 mbar more boost pressure by redline. This directly translated to more horsepower and torque, while everything ran cooler and more efficiently.
