Read the entire instruction manual before beginning installation. Some stock parts will
be used in reassembly.
In these installation instructions, torque specifications are given in both in-lbs and ft-
lbs. Verify that the torque wrench is set to the proper setting before torquing the bolt.
Failure to do so could lead to either loose bolts or to bolt heads being torqued off.
Installation of the Edelbrock E-Force supercharger on to the C5 Corvette requires
permanent modification of the supercharger casing in order to provide the clearance
needed.
If your vehicle has an aftermarket oil cooler installed, make sure that the heat exchanger
and the oil cooler still allow sufficiant air flow to the radiator.
The E-Force supercharger will not run on the Original Equipment Manufacturer (OEM or
“stock”) C5 fuel pump. The OEM Corvette C5 fuel pump does not provide enough fuel
flow to maintain the correct air-to-fuel ratio. You will need to increase the fuel flow. Two
recommended solutions are voltage boosting the stock fuel pump, via a Boost-a-pump kit
(PN: KB89067) or changing to a high flow replacement fuel pump (PN: L710650197).
This kit requires the replacement of the OEM spark plugs as the OEM spark plugs are
not designed for the high cylinder pressure and heat that is created with the addition of
a supercharger. LPE recommends using LS9 spark plugs (PN: 41-104) or plugs that are
equivalent in heat range.
LPE has found that valve float tends to occur on LS1 and LS6 engines when a
supercharger or turbocharger is added to the engine. LPE recommends springs with
higher seat loads and spring rates to overcome the problem. The recommended valve
springs are listed in the Additional Required Components parts list.
Installing this supercharger will significantly increase engine performance. Due to this
significant increase in performance, it is recommended that the vehicle be inspected
before installation of the supercharger system to make sure the vehicle can handle the
increased performance. This includes checking the clutch condition and performing leak
and compression checks.
This supercharger kit requires premium fuel levels. LPE recommends using 93 octane
fuel. Use the highest available octane fuel if 93 octane fuel is unavailable.
This kit is currently not designed for top post batteries. Cars equipped with top post
batteries will need to be converted to a side post battery.
This kit is currently not designed for 1997-1998 model year vehicles due to fuel system
differences. Additional components would be required to adapt this kit to a 1997-1998
model year vehicle.
Installation of this kit requires the installation of an aftermarket hood to provide
clearance for the supercharger. The OEM C5 hood does not have enough clearance
under it to allow for the supercharger. LPE recommends the C5 Corvette SCIC Hood (PN:
L850060197).
