Synapse: According to PET their New CEA Turbine Wheel deliver: - Faster Spool-Up - More Horsepower "PRECISION TURBO AND ENGINE releases their all new ultra high-flow CEA (Competition Engineered Aerodynamics) turbine wheels! Specifically engineered to produce massive power gains over older turbine wheel designs, usage of Precision’s new CEA wheels typically results in an average increase of 30-45 horsepower over comparably-sized standard designs. Furthermore, spool-up time is improved when using PTE’s CEA turbine wheels to further reduce turbo lag. Precision’s current 62mm turbine wheels will be replaced by the new 62mm CEA version whereas the current 65mm turbine wheels will be replaced with a newly-developed 66mm CEA wheel. Utilizing an enhanced design, the new ultra high-flow turbine wheels will come standard on all of Precision’s 62mm and 66mm turbochargers that also feature the exclusive CEA compressor wheels, both ball-bearing and journal bearing versions, including the 5862, 6262, 6266 and 6766 units." ---PTE
