THE POWER OF A RACE-BUILT 5.0 V8

The entire top end of the engine was developed with race bred technology. Free breathing cylinder heads with large intake and exhaust ports ensure greater power output. Higher lift camshafts increase valve opening, and together with a larger diameter electronic throttle, allow the engine to gulp huge volumes of air.

PERFORMANCE THAT REALLY PUMPS

For durability, an oil scavenging pump (pure race bred technology) captures oil forced to one side of the engine by the high G-forces of fast cornering, and pumps it back into the sump.

LOWER WEIGHT, HIGHER REVS WITH TITANIUM VALVES

Conventional valves begin to 'float' at faster engine speeds, restricting ultimate performance so Lexus engineers installed larger titanium intake valves. This allows increased air and fuel into the cylinders and reduces heaviness so they perform better at higher engine speeds.

DUAL VVTi OPTIMISES PERFORMANCE AT ALL ENGINE SPEEDS

For enhanced output whatever the engine speed, the timing of both the intake and exhaust cams is continually retuned by Dual Variable Valve Timing with intelligence (VVT-i). On the intake valves, Electric motor driven VVT-iE which responds much faster, delivering further gains in performance.

A FREE BREATHING DUAL INTAKE SYSTEM

A dual stage cold air intake optimises airflow into the engine according to engine revs. To increase air velocity into the cylinders at lower speeds for increased torque, only the primary intake is used. Above 3600 rpm, the larger secondary intake opens for increased high end performance, also contributing to the IS F's distinctive high speed howl.
