Precision Engineering & Balance
Achieving optimal balance is critical for every TTE turbocharger, ensuring both longevity and peak performance. Properly balanced components not only enhance reliability but also improve acoustics. Each TTE turbocharger undergoes meticulous balancing at every stage:
-
Component Balancing – Individual parts are balanced at slow speeds up to 2,800 RPM in multiple planes using our dedicated single-part machine.
-
CHRA Dynamic Balancing – Assembled cores are dynamically balanced using our in-house VSR machine, reaching up to 250,000 RPM depending on application. This ensures ultimate equilibrium, far exceeding OEM standards.
Every TTE680 turbocharger is delivered with a serial-numbered balance test report, certifying the precision and quality that define TTE upgrades.
