Lingenfelter 2006-2011 Z06 Corvette
For those of us with a heartbeat and even a vague interest in anything Chevy, Lingenfelter has become known as somewhat of an icon in the Corvette world. So, it should come as no surprise that Lingenfelter has come around once again to throw down some serious power down from the Z06, lest anyone forget the powerhouse that emanates from Decatur, Indiana. In their impressive lineup of ridiculously powerful, yet completely street drivable cars, the single staple that we can always count on from Lingenfelter is the Corvette. Coming 
from a company who was founded on the blazing speed and power that came from their original Lingenfelter Corvette, nothing should be discounted on their new endeavors. After all, this is the same company founded by the guy whose 2001 Corvette managed a 1.97 second 0-60mph. Most people on planet earth haven't had the opportunity to accelerate that fast.
The package Lingenfelter Performance Engineering -or simply LPE- put together for the C6 Z06 is a complete teardown and rebuild of the LS7. This means you drop your beauty off (where it will initially be dyno'd for the "before" numbers), to be massaged and reconstructed at the loving hands of the team in Indiana; then pick your beauty back up, with a new snarling beast under the hood. The fellows at LPE first pull your engine, and disassemble it to CNC port and polish your cylinder heads for a better flow, optimized for components soon to be listed. After the porting and polishing, the LS7 gets a multi-angle valve job, and resurfaced for a slight bump up to 11.5:1 compression. Then things begin to get reassembled and prepped to be ready to rock on with some brand new components. Ferrea high performance dual valve springs are chosen, along with titanium retainers and valve locks. A Lingenfelter Z06 GT19 camshaft is implemented, crafted by none other than Competition Cams. To feed the beast, Lingenfelter has designed a high flow induction system coupled with a LPE 4" ID mass air flow sensor. All of this flows into a port-matched LS7 intake manifold controlled by a ported and polished LS7 throttle body. Mating everything together are official GM head gaskets and head bolts. To keep everything running smoothly and coolly- is a 160 degree thermostat. This whole beauty gets assembled by a LPE tech in house, and then tested and tuned. This means, not only is the whole package placed back into your beauty, but then it gets tuned, and tested to perfection by the hands that crafted it, and know it best- inside and out, literally. This team of engineers wrestles- gently but firmly- with your newly tempered beast, to extract somewhere in the neighborhood of 630bhp, and 570 pound feet of American muscle.
This build by the best, comes with a three year/36,000 mile warranty, and a certificate of authenticity. The whole package comes in at $10,146, and overall for the level of work, and the power it outputs is a pretty great deal. The team at Lingenfelter has become 
renowned for maintaining and incredible level of drivability on their builds, while being able to muscle up at the right moment and output tremendous amounts of power. The highway mileage for the Z06 remains the same as it was the day it left Bowling Green, but puts out another 120 hp. Granted, their test car had long tube headers on it by American Racing, which if you're truly looking at putting out this kind of power; it would be silly not to implement the use of long tube headers. The turnaround time for the entire installation is 3-4 weeks with prior notice to LPE.

The crew over at Automobile Magazine also had the chance to drive one of the Z06's LPE has put together and matched it up against a Dodge Viper SRT-10, if you would like to read the article check it out here.
