Sorry to kind of go off topic, but now I'm kind of curious about power levels on a single set of 1600s.

In that post Chris says they stopped at 600awhp because they maxed out a single set of 1600s. Given that was on e98, but can are you really going to gain much more power without knocking with e85?
Has anybody else heard of people maxing out 1600s before and what kind of power they were putting down?
