Does anyone know where to get HP numbers of the '03 MX-Zs?

Well from what ive heard, here are some numbers from (from 02, except the HO). MXZ 500= 97hp MXZ 600= 108hp MXZ 700= 122hp MXZ 800= 134hp MXZ 600HO= 121hp compare that to F5= 104hp F7= 138hp (more then the mxz 800) from what ive heard, its quite hard to believe this, but someone claimed to have seen it at a dyno 4 times.... RX1 AT THE TRACK YES AT THE TRACK= 146HP. a little hard to believe.
