 The LS7 oil cooler is replaced...  The LS7 oil cooler is replaced with one from the LS9 engine. Edelbrock includes the oil cooler in the kit.  Our test vehicle was equipped...  Our test vehicle was equipped with an early edition of Kooks long-tube headers, and the oil cooler had no problems clearing the primary tubes. According to Howard Tanner, the newer-style Kooks, American Racing Headers, and some other popular systems will have no issues clearing the LS9 cooler.  Our kit had a prototype valley...  Our kit had a prototype valley pan; Edelbrock has since changed the design.  The E-Force comes together,...  The E-Force comes together, minus some small stuff like fuel injectors, rails, and other ancillary items. It took both Tanner and Hotaling to hoist it up and get the unit on top of the engine.  The stock injectors are replaced...  The stock injectors are replaced with 74-lb/hr units, which are supplied by Edelbrock. The kit also includes the EV6-to-EV1 wiring adapters for the new injectors.  The fuel injectors are installed...  The fuel injectors are installed in the fuel rail, and the rail is bolted to the manifold.  Redline changed the spark...  Redline changed the spark plugs to NGK TR6 pieces, which are one heat range colder due to the supercharged combination. Hotaling gapped the plugs at 0.032-inch.  The OEM 90mm throttle body...  The OEM 90mm throttle body is carried over from the stock intake manifold.  The factory MAF sensor is...  The factory MAF sensor is inserted into the new Edelbrock cold-air kit.  15 The air-to-water intercooler...  15 The air-to-water intercooler utilizes a front-mounted heat exchanger to keep the intercooler-liquid temperature at reasonable levels.  One of the greatest advantages...  One of the greatest advantages of the E-Force system over other Roots-style kits is its ability to fit under the factory hood. This is accomplished thanks to a couple of spacers used on the engine cradle to lower it down.  Edelbrock finished off its...  Edelbrock finished off its supercharger system with a set of cast-aluminum engine covers that add style and a unique look.  With everything buttoned up,...  With everything buttoned up, Tanner cracks open the EFI Live tuning software to recalibrate the ECU for the newly boosted LS7 combination.  This graph shows the comparison...  This graph shows the comparison between naturally aspirated and E-Force supercharged. The torque is far more aggressive, and the hp is up considerably to 632 rwhp—putting it in ZR1-killing territory.
