Kinugawa Turbo Ball Bearing 3" Anti-Surge TF06-18K Stage 2 for HYUNDAI Genesis Coupe 2.0T BK1 BK2

• Priority: Highest
• Impact on Spool Time: The A/R ratio directly influences the exhaust gas velocity and energy reaching the turbine wheel. A smaller A/R ratio generally leads to faster spool-up due to increased exhaust gas velocity, but it can also limit top-end power. A larger A/R ratio results in slower spool-up but can support higher power levels at higher RPMs.

2. Turbine Wheel Design:

• Priority: High
• Impact on Spool Time: The size and design of the turbine wheel affect its inertia and how efficiently it extracts energy from the exhaust gases. You can check their turbine maps to determine their performance capacity. A smaller and lighter turbine wheel will typically spool up faster, but it might have lower peak power potential. The blade design also plays a role, with some designs optimized for faster spool-up.

3. Compressor Wheel Design:

• Priority: Moderate
• Impact on Spool Time: While the compressor wheel itself doesn't directly impact spool time, its design and size influence the overall balance and efficiency of the turbocharger. A larger compressor wheel requires more energy to spin, which can slightly increase spool time. However, a well-matched compressor wheel can improve overall efficiency and reduce backpressure, indirectly aiding spool-up.

1. Touch:  Anti-Counterfeit filaments, randomly allocated on the Anti-Counterfeit Tag, are solid and 3-dimensional. Consumers can touch, feel and look at the Tag to verify its authenticity.

Precisely balancing our turbochargers is a key critical factor for longevity and performance. Good balance also improves acoustics. Subsequent great care is taken with all Kinugawa turbochargers in this regard. Firstly parts are balanced at slow speeds up to 2800 RPM in multiple planes using our single-parts machine. These parts assembled to cartridges (C.H.R.A) are dynamically balanced yet again, but this time at up to 100,000 RPM in multiple planes using our in-house VSR machine to acquire the ultimate equilibrium to a standard far higher than OEM. We supplied a balance test result document.
