Presentation of the Upgraded Turbocharger by RTMG PERFORMANCE

What is a hybrid turbocharger, and how did it become popular?
The hybrid turbocharger became known many years ago when turbocharger repair shops, in order to fix damaged turbos, started using larger compressor wheels and shafts to cover up the damage caused by wheel-to-housing contact. That's how it all began. After a proper repair, many workshops noticed an increase in power, while some experienced a decrease due to poor workmanship or lack of knowledge.

What is a hybrid turbocharger?
It's essentially the same factory turbocharger but with larger compressor and turbine wheels, allowing for greater airflow. More airflow, combined with more fuel, equals more power. The greatest benefit of a well-built hybrid turbocharger is that it doesn't require additional modifications for a larger turbocharger, such as custom manifolds, oil lines, water pipes, air pipes, or exhaust system modifications. These are huge benefits that make the hybrid turbocharger an ideal upgrade when done by professionals with the right CNC machines, reinforced bearings, dynamic balancing with a VSr machine (which balances dynamically to 0.01 g), and performance testing before and after. It is the best value-for-money improvement.

Our Expertise
Our team has a dedicated group of engineers with 15 years of experience in turbocharger repair and upgrades. We own brand-new CNC machines, use advanced CAD-CAM design software for simulating forces, and design high-performance components such as bearings. We also have the latest generation 2024 precision balancing equipment, which measures and tests the performance of the turbo before and after the upgrade in cubic feet per minute (CFM). This is very important because a wrong choice of wheel size that doesn't match the housing can disrupt the energy balance, performance, and spool time of the turbocharger.

Why Choose Our Hybrid Turbochargers?
One of the most important aspects of our services is the perfect fit we achieve with our CNC machines between the turbine and the housing, as our machining precision reaches 0.001 mm. This is crucial, as we follow ISO 9001-2018 standards, which ensures repeatability in every product we manufacture. Another advantage of our hybrid turbochargers is the low-speed balancing done before the VSr balancing, which measures up to 300,000 RPM. During this process, we test the components' behavior under near-real conditions, checking for oil leaks and other issues.

All these steps are included in every RTMG PERFORMANCE turbocharger, and we provide documented results. This, combined with our passion for improvement, has earned us many records and a legacy of satisfied customers worldwide. We never stop researching and developing, as this continuous improvement process allows us to push the boundaries of automotive performance.

Attention: Factors for the Proper Operation of the Turbo

a) Ce turbo nécessite une admission d’air froid de plus grand diamètre pour fonctionner efficacement.
b) Un intercooler capable de gérer un débit d’air supérieur à la capacité du turbo est nécessaire.
c) La pression d’huile doit être maintenue à 5 bar.
d) Un réglage approprié de l’ECU est crucial pour les performances et la fiabilité. Un calibrage correct empêche la fermeture du papillon, garantissant un fonctionnement fluide.
e) Le catalyseur doit supporter plus de puissance que celle produite par le turbo. En général, un catalyseur métallique 100 cellules est recommandé. La spécification de la ligne d’échappement est optionnelle mais doit être adaptée à la capacité du turbo.
f) La qualité et l’état de l’huile doivent répondre aux exigences des hautes performances.
g) Il est essentiel de vérifier régulièrement le circuit de pression d’air, en maintenant au moins 2 bar, afin d’éviter le survitesse du turbo.
h) Une soupape de décharge mécanique est recommandée, car les soupapes d’origine peuvent ne pas se fermer correctement, entraînant une survitesse du turbo.
