With a Stock LS9 no Less

Lingenfelter Performance Engineering has done it again. Using a stock LS9 with factory exhaust manifolds, no less, LPE has managed to run 9.81 at 145mph. Lingenfelter's supercharger upgrades along with a few bolt-ons as well as slicks and skinnies helped their development vehicle become the fastest in the land. The Decatur, IN group says the ZR1 makes 739-rear wheel horsepower and 740 lbs-ft of torque at the wheels taking advantage of LPE's catalogue of new Corvette parts.

"The track is the ultimate proving grounds to showcase Lingenfelter's years of engineering expertise and to test the performance capabilities of our ZR1," said Ken Lingenfelter, owner, Lingenfelter Performance Engineering.  "We are excited to continue developing product that pushes this sports car to the limit."
