what would the speed be for an '07 Pantera with Nitrous c cams, shoot thru, 30" draw length set at 70# pull using a 380 grain total weight arrow, NAP 360 rest, g5 meta peep and BCY loop material is only thing on my string?

I wouldn't even venture a guess. I know when I had ine it was doing 287fps shooting 5 gr/lb at 27" and 53#.

Depending on whats on your string ( peep, nocking point, loop, etc ) I guessed 15 gr and that gaive about 305 fps and 78.6 KE.
Also guessed at your bows rated speed, here's the link to the Energy and Speed Calculator. :)

There was never an IBO speed advertised for this bow as it's not a standard production bow. The bow was produced with the MPro cam on it. The Nitrous X systerm was either a custom order or changed after it was bought. Martin does not publicise IBO speeds for custom order bows. The IBO is what it is. Rest assured, with the Nitrous cams on it's way faster than that with a MPro cam.

I told you the speed I was getting. That was with the module at it's shortest setting. Shooting a longer draw length will definitely produce more speed as more of the bow's efficiency is being used.

I know and never said there was an advertised speed.

You owned a Pantera with Nitrous too? Gets me thinking......... :)

Yes, I ordered it for my 2007 bow. I sold it to Alec (Flytier17). I don't know if he still has it and he's been hiding so can't chime in.
