Not necessarily Sloppy. The issue is that our stock turbo's make power very early and run out of breath up top. If you can HOLD 400TQ all the way to redline, you'll make a ridiculous amount of HP. Simply, HP is a function of TQ x RPM. Therefore if you can maintain high TQ at a high RPM, your making a lot of HP.

So...

All we need is a turbo that doesn't run out of breath up top. Then we are golden.
