Hondata's peak numbers are a bit inflated relative to others because he ran his car on Church Automotive's Dynapack dyno (load-based) which reads about 10% higher than a Dynojet (inertia-based), typically a more consistent dyno type than others. In addition, he was running a velocity stack (i.e. no filter) which I bet netted him another 3-5whp. As a result, Doug's 338whp on the Dynapack would translate to only about 304whp on a Dynojet. I mentioned this in one of Doug's thread and he confirmed it. When comparing peak dyno numbers, you have to compare apples to apples because all dynos can be calibrated differently (though less so with Dynojets). Ultimately, the main comparison should be between baseline and modded numbers to determine overall gains.
Based on his (and my) experience, I believe that the max output with S/C + bolt-ons is around the 310-320whp range as the M62 is already at it's peak efficiency at 9-10psi. I'm currently at 310whp (on a Dynojet), but my water/meth injection is on the conservative side. If my car was tuned more aggressively, I'm sure I could extract another 8-10whp, but I don't think I'm willing to risk a blown motor in the event of a pump failure for such a relatively small gain.
