After upgrading the engine valve springs, adding a second fuel pump, and going with 100% over-flow injectors, this beast is now at the next level with a third turbo that works in conjunction with the hybrids I had before. It makes nearly 750hp/1000lb-ft of torque at the engine and the wheel numbers are very close to 600whp and 800wtq. Clutch was slipping a lot so that will be upgraded soon.
