CONGRATULATIONS
Your new Whipple Supercharger is engineered to significantly increase your engines power across a broad range of RPM’s.
It is Whipple’s goal to improve your driving experience for many miles and years to come.
Whipple Superchargers operate as an air pump and contain internal rotors that are driven by the engine’s crankshaft and
serpentine belts. The supercharger compresses outside air and channels it into the engine’s intake ports. Because of their
design, superchargers may generate some additional noise over the standard, normally aspirated induction system.
At idle, you may hear a medium-pitch rattle from the supercharger main housing. This will diminish at about 400-500 rpm
above idle.
You may also experience a muffled high-pitched whine during acceleration. This is caused by the pumping action of the
supercharger compressing air and only occurs during boost conditions. It is inaudible during part-throttle acceleration.
These are normal noises associated with any supercharger and have no effect on supercharger performance or engine
durability.
Your supercharger is warranted by Whipple Superchargers, please see your terms and conditions on the back of your invoice
for more information in regards to the limited warranty. NOTE: Whipple Superchargers will not authorize any warranty
repair work or supercharger replacement for normal noise.
IMPORTANT INFORMATION
CHASSIS DYNO
Due to the 130mph speed limit, one must always run in a gear that will not limit the engine rpm below 7000rpm. Therefore, 5
th
gear is
the preferred gear. 7
th
gear is 1:1 and gives the highest power results, but is not available due to drive shaft/ tire safety and thus will
reach a limit far before peak power is made. Never run back to back runs without a proper cool down. You must let the engine cool down
for 5 minutes between runs as you won’t have adequate airflow to keep the vehicle in proper temperature ranges.
BOOST LEVELS
All Whipple kits are shipped with boost levels that Whipple feels achieves maximum power while maintaining reliability with stock engines
(@ sea level). Higher boost levels must run higher octane levels and are not supported.
EXHAUST
Cat-back exhaust systems help reduce heat and minimize exhaust back pressure. They do not affect the calibration and are always a
good idea for added safety and performance. Long tube headers and/or high flow cats require custom calibrations and are not supported
by Whipple nor emissions legal.
FUEL OCTANE
Never run a fuel octane that is below 91octane, (RON+MON)/2 and never run fuel with more volume than 10% Ethanol. It is
recommended, when available, to run 92-94 octane. Never mix mid-level (below 91) with 91+, this is very dangerous and can cause
severe engine damage. Do not attempt to increase octane ratings with generic octane boosters, these are very hard on spark plugs and
many brands do very little to the actual octane rating (1 point is .1 octane). For emergency situations and racing applications, the best
octane booster found to date is Boostane (#1 choice). Some other brands are hard on spark plugs so constant use will require increased
spark plug maintenance. The PCM constantly adapts, if it senses better fuel, it will increase power accordingly.
ENGINE COOLANT
Whipple recommends running a 50/50 mix of distilled water and coolant. The engine temp should run between 195-215deg F under
normal driving conditions. We also recommend 1-2 bottles of Red Line Water Wetter coolant additive. This will reduce air bubble
insulation, which increases overall engine temp.
FUEL LEVEL
Never operate at WOT when the vehicle fuel levels are below a 1/8 tank. Low fuel levels could cause the fuel pump to cavitate and you’ll
have fuel flow spikes resulting in lean conditions and consequently detonation.
