Hi Ryan,

Let me respond to your question. (Excuse the verboseness)

First, regarding the technical specifications that I know of and at times
speculation from what I do know.

1) MP2x000 (I believe the stated speed by Apple was either 161 mHz
or 162 mHz.

MP2x00(STK): 44 x 3.686 mHz = 162.184 mHz

MP2x00(TUR): 44 x 5.000 mHz = 220.000 mHz

Depicted here in my Turbo Hack Diagram:

219.46444440616 mHz 162 mHz = 57.46444440616 mHz Increase
57.46444440616 mHz / 162 mHz = 0.35471879263 so it is approximately
equivalent to a 35.5% increase in speed (so I stand corrected that it's not
33% by around 35.5% which if rounded up would be 36%) hopefully my math
hasn't degraded to the point that I need a refresher course and my logic
here is valid ;-P

MP2x00(CRZ): 44 x 6.250 mHz = 275.000 mHz *the crystal speed is an
approximate guess here.
In an example on the internet that proved that in an extreme case it could
be exceeded to a faster speed and one such proof was this photo of a MP2x00
running at a blazing 275.229999951988 mHz

2) eMate 300 (Since we know that Apple Spec'd the eMate 300 at 25
mHz)

eMate 300 (STK): 6.8 x 3.686 = 25.0648 mHz

eMate 300 (STK): 6.8 x 5.000 = 34.0000 mHz *Sorry I do not yet have a photo
of my eMate 300 with a speed calibration shot. Never did have a camera handy
back then. But I will try to rectify that in the near future.

34.000 mHz 25.000 mHz = 9.000 mHz Increase
9.000 mH/ 25.000 mHz = 0.360 so it is a 36% increase in speed

So the Turbo Hack for the MP2x000 & eMate can be stated as approximately 36%
increase in speed.
I'm not sure where you got the 50% increase in speed from Ferdi's site, but
if it is stated there then I'd doubt the correctness of that statement.
Of course there is always the possibility that he is using a different
crystal.
HTH
