1999 Chevrolet Corvette Lingenfelter Twin Turbo Test Drive

After 2 years of development, master tuner John Lingenfelter hit a horsepower wall with the naturally aspirated LS1 aluminum v8. The compromises necessary to keep the v8 emissions legal in running properly under the watchful eye of OBD2 government regs limited the possible modifications. That didn’t stop Lingenfelter from trying, however, and his 383 cubic inch, 450 horsepower LS1 is no slouch. Installed in a C5 Corvette, the 383 pushed the car to 60 MPH in 3.9 seconds and through the quarter mile in 12. 1 seconds at 120 MPH.
