SEMA 2012: Lingenfelter Performance Engineering Knows the LS

It’s always fun visiting with the guys from Lingenfelter Performance Engineering – there’s always something new and interesting to see, and this year’s SEMA show was no exception. LPE develops scores of new products for late-model Chevys every year, and we’re not talking about new shift knob applications, either. LPE is staffed by hardcore enthusiasts and racers, and it shows.

LSA to LS9

A good example of the kinds of goodies they typically churn out is the LSA to LS9 supercharger conversion front cover shown above. As you probably know, one of the differences between the Corvette ZR1’s 638 horsepower LS9 and the less-powerful LSA under the hood of the Camaro ZL1 and Cadillac CTS-V is the size of the supercharger. This new component from Lingenfelter allows the use of the LS9’s TVR2300 blower on an LSA without changing the accessory drive layout or the throttle body location. Speaking of throttle bodies, it allows the use of up to a 105mm TB, and the pulley is compatible with LPE’s line of 10-bolt overdrive pulleys.

For those running a centrifugal supercharger or turbo(s), LPE has this very tidy intake manifold with an integrated air-to-water intercooler. It’s available in versions for both cathedral port and square port heads, and will support as much as 1,600 horsepower, according to Lingenfelter.

  • Low pressure drop design
  • Stacked double pass core
  • Core dimensions: 8″ wide x 15.5″ long x 3.5″ tall

Of course, making big power with a pressurized LS means you’ll have to beef up the rest of the drivetrain to get those ponies to the ground. Lingenfelter has you covered there too, with parts like this 9.5 inch differential assembly for the 5th Gen Camaro.

  • Custom cast aluminum housing
  • TracRite helical limited slip differential
  • OEM GM truck ring & pinion in 3.42, 3.73, 4.10, or 4.56 ratios

LPE also offers the differential set up with either a preload bias set for street/strip applications, or no preload for road racing. The differential doesn’t require any body or frame mods, and uses OEM or aftermarket differential bushings.
