Why Choose the Boost Lab BL6662X Billet Turbocharger?
Engineering for Maximum Efficiency
The BL6662X features a point-milled billet 66mm compressor wheel and a newly engineered 62mm Inconel turbine wheel, providing exceptional airflow and reduced exhaust restriction. This results in faster spool, improved transient response, and superior top-end power.
Dual Ball Bearing Durability
Built around a dual ball bearing, oil & water-cooled CHRA, the BL6662X offers outstanding reliability and high-boost capability. Water cooling is required for optimal performance and long-term bearing life under extreme conditions.
Assembled & VSR Balanced In-House
Every Boost Lab turbocharger, including the BL6662X, is VSR balanced using Turbo Technics equipment at our facility in Dade City, Florida. This ensures minimal vibration, reduced noise, extended bearing life, and maximum performance consistency.
