Pipe assembly 84492718 can be purchased to obtain the quick connect fitting for custom builds.
Variable Camshaft Timing
This engine has the ability to vary the camshaft position versus the piston position. If you chose to use the Chevrolet Performance
engine controller kit, then it will vary camshaft timing to improve emission and fuel economy, while still producing great power. At
idle, for example, the cam is at the full advanced position, allowing exceptionally smooth idling. Under other conditions, the phaser
adjusts to deliver optimal valve timing for performance, drivability and fuel economy. At high rpm it may retard timing to maximize
airflow through the engine and increase horsepower. At low rpm it can advance timing to increase torque. Under a light load, it can
retard timing at all engine speeds to improve fuel economy. A vane-type phaser is installed on the front of the camshaft to change
its angular orientation relative to the sprocket, thereby adjusting the timing of valve operation on the fly. It is a dual-equal cam
phasing system that adjusts camshaft timing at the same rate for both intake and exhaust valves. The system allows linear delivery
of torque, with near-peak levels over a broad rpm range, and high specific output (horsepower per liter of displacement) without
sacrificing overall engine response, or drivability. It also provides another effective tool for controlling exhaust emissions.
Intake Manifold/Supercharger Assembly
The LT5 Roots-type supercharger is a positive displacement pump that consists of 2 counter-rotating rotors installed into the lower
intake manifold housing. The rotors are designed with 4 lobes and a helical twist. The rotors of the supercharger are designed to
run at a minimal clearance, not in contact with each other or the housing and are timed to each other by a pair of precision spur
gears which are pressed onto the rotor shafts. The rotors are supported at each end by self-lubricating non-serviceable bearings.
The drive belt pulley is pressed onto the input shaft. The input shaft is coupled to the rotor shaft. Both the belt pulley and shaft
coupling are also non-serviceable.
The upper intake manifold housing has an integrated intercooler system. Cooling the air enhances the effectiveness of the
supercharger. The intercooler uses conventional coolant in a separate system from the engine cooling system. The intercooler
system includes two charge air coolers/heat exchangers, a water manifold assembly, and a variety of sensors to monitor air
temperature and pressure. The water manifold, located at the front of cover transfers coolant to the cover via four internal transfer
tubes. The transfer tubes and water manifold are sealed with O-rings and press-in-place seals. Coolant enters the inlet port of the
water manifold assembly, is directed into and through the two charge air coolers/heat exchangers, and exits back into the water
manifold. Coolant then exits the water manifold outlet port returning to the separate cooling system. The two charge air coolers/
heat exchangers are not serviceable.

•
Lower Intake Manifold Housing, to include rotors, gears, bearings, shaft coupling, and drive belt pulley
