105.
Cycle the ignition to the ON position again and repeat until the sound of the electric pump is continuous without any
pulsation and the fluid level is met at the filler cap.
NOTE: During water pump start-up, it is normal for a
slight pulsation to occur. Once the pump has reached its maximum cycle speed, no pulsations should
be present. If any pulsations occur, there is air in the system.
NEVER GO WOT UNTIL AIR IS BLED OUT!
106.
Several drive cycles may be required to completely purge the air from the intercooler system. During a drive cycle,
the intercooler system will build up pressure as the supercharger temperature increases. Any residual air trapped in
the system will have to be bled out when the cap is removed. Use a rag when removing in case there is excess
pressure.
TIP: Never go WOT until air has been bleed from IC system, engine failure could occur if not
bled properly.
107.
If your system included a flash tool, follow the included instructions to reflash the PCM.
108.
Install the radiator shroud cover using the factory push pins.
109.
Reinstall the grill shell in the reverse order.
Verify proper clearance to the intercooler hoses added,
specifically the 180 deg heat exchanger feed hose as it will be close to the front grille. If interference
is found, loosen pinch clamp and rotate hose away from grill shell.
110.
Turn the Ignition key on, do not start the engine (this will turn ON the fuel pump for 2 seconds). Inspect for leaks
such as fuel, coolant, and intercooler coolant, correct as required.
111.
Start the engine and let idle. The engine should idle normally between 600-800 rpm at normal operating temps.
Inspect for leaks. After running for 2 minutes turn off engine and inspect the level in the engine radiator and the
Intercooler tank. With the key in the ON position engine off, inspect the coolant in the intercooler tank, the coolant
should flow in the tank. If it does not, the coolant circuit has an air pocket trapped in it. To remove the air pocket,
with key off, remove the IC filler neck cap and fill with coolant to mid-level. Reinstall cap, turn key on, for 15 seconds.
Turn key off, remove fill cap and repeat until all air is bled.
112.
Before driving, make sure that you have 91 or higher-octane fuel in the system. Not ½ tank of 87 and ½ tank of 91,
all 91 or better fuel in the system. Whipple does not recommend octane booster for low octane fuel. The system
adapts to higher octane fuel when it’s available.
113.
Test drive vehicle for the first few miles under normal driving conditions. Listen for any noises, vibrations, engine
misfire or anything that does not seem normal. The supercharger does have a slight whining noise under boost
conditions, which is normal. If you chose the 132mm billet throttle body, idle may take a few minutes to learn. Using
the Tomahawk tool and the data logging options, use the Whipple List and check the MCT reading while operating.
This is the Manifold Charge Temperature. This is post intercooler, normal temps are 0-40deg F over ambient under
normal conditions.
114.
Re-check the radiator and intercooler reservoir coolant level regularly over the first 1,000 miles, top off level as
needed. Do not operate at WOT until IC system is bled properly.
115.
Re-check SC oil level regularly over the first 1,000 miles, level may drop very slightly as it fills the bearings and
cavities.
116.
Inspect belt system, readjust if necessary. It’s common for the belt to stretch after first use.
WARNING: Always avoid removing the filler neck cap when the system is hot. The hot coolant is under
pressure and may spray out causing burns.
WARNING: Triple check that the intercooler system is properly bled. Failure to do so can result in engine
damage. Turn ignition on, let the pump run for 60 seconds, there should be zero cavitation during this
test.
