I think you might have misunderstood my statement about the MN12 part.
I was saying that the Coyote in stock trim with supporting trans and rear/suspension mods could pull of 12's. No MN12 that I'm aware of in stock form with just trans, rear, suspension mods can even come close to that. You have many mods done to your motor and are in the 12's NA which is impressive, but a Coyote in stock form can do it just by figuring out how to get it in there.
Hope that clears it up some, we do basically agree on everything else lol.
I don't have many mods to my motor as Robert pointed out. I have switched to stock PI heads to bump the compression on a stock NPI shortblock and a small set of cams. I do have the bullitt intake and TB to help induce airflow. So its nothing really special and has 2 less valves and less compression.
A stock Coyote has what 415 HP? A stock NPI MN12 96-97 version had what 205 HP? Stock 4.6 had maybe 9.4-1 compression. A Coyote has 11.0-1 or so. 2V vs 4V. Technology!!! I agree with that.
Also take into account parasitic drivetrain losses. Again Technology.
Robert is correct. There have have been stock NPI cars run down in the 13's-High 14's with no engine work other than tunes, converters, gears and a better exhaust. The Mustang in its form has in some way implemented all that in the drivetrain with better gearing both trans and rear, Manual option of course, and a solid axle generally robs less power than a IRS and is much more stable for track purposes. I read somewhere that the heads on the coyote are the most efficient that Ford has ever produced. A lot different than an NPI 2V Bird/Cougar.
Again, I'm not disputing the technology and I think we all agree on what Kris said about that. But I also agree you can make a 2V more efficient by upping compression, adding better heads, cams exhaust and refinining the drivetrain to a point that they run well.
Mine is proof of that, BUT, IT AINT NO COYOTE!!
