This customer drove in from Georgia for our Purple Belt Performance Package, along with the new Caddy Issues turbochargers and Tapout Stage 2 cams. Using the industry standard SAE correction factor he put down 744 whp and 816 wtq on E87 fuel. This is the most torque ever produced by an LF4 engine. And the area under the curve is monstrous. Notice how the torque and/or horsepower was above 700 all the way from 4,000 to 6,800 rpm! Switching to STD correction factor boosted the numbers to 761 whp and 835 wtq. Engine block, rotating assembly and cylinder heads are all still stock.
