Beskrivelse

FVD Spec. Billet 911/ 930 Turbo Cylinder Heads:

• Interchangeable fit with 911/ 930 Turbo standard cylinder head
• Fully CNC machined from solid billet for maximum geometrical accuracy
• Made from Aerospace grade 2618 aluminum alloy, as commonly used for F1 & GT race pistons which has the highest possible material strength at elevated temperatures
• Machined for Intake and exhaust valves
• Optimized combustion chamber reduces squish crevice volume - the effect of which increases chamber turbulence and results in higher flame speed, which improve's power, torque and efficiency.
• 15mm outside diameter sintered steel valve guides for reduced wear & improved valve support at high temperature
• Sintered steel valve seats for maximum life & heat rejection from valves
• Advanced Intake & Exhaust port design (Optimized for high velocity)
• Solid lower fins for maximum strength around cylinder seal
• Small diameter spark plugs to reduce stress around plug holes
