I posted the same video in the Camaro/Mustang thread. If it's a regular GT, it's not great news for 392 owners.

We don't know if it was a stock Mustang either. I agree that the back wheels & tires look seriously wide for one thing, which might suggest other mods have been done too. A simple tuner could add 25-30 HP. Not sure if the Mustang was an auto or a stick either.

While the auto 392 has the advantage out of the hole, once rolling the 392 manual has closer spaced ratios and less parsitic loss and just might win a roll-on against a 392 auto (and thus do better against that Mustang).

It did look like the 392 held him in one of the roll-ons from a lower speed. Looked pretty even all they way out to the let-off.

Anyway, the Mustang GT is no push-over and I wouldn't recommend taking that car lightly or you just might be looking at his tail lights.

Considering how rich Dodge runs these engines at WOT and how much spark advance is left on the table, I'm pretty certain a Diablo CRM tune on a 392 is going to yield a serious power/torque increase - like 30-35 HP and TQ on 93 octane.

We have no idea if that Mustang is stock. A more telling video is the Mustang GT/CS 392Pusher ran against in his bone stock auto 392 with a green engine.

That Mustang had a CAI, X-pipe, exhaust, and a 91 octane tuner (brand not specified) and was making around 450 crank HP (412 is stock).

He got the jump on 392Pusher by 1/2 car length because he popped the aftermarket clutch and got a nice hard launch whereas 392Pusher has the ESC light flashing and it was pulling power. Once the ESC turned off, the 392 strongly pulled back even and it was nose-nose out to 110+.

Based on what I know intake, tuner and exhaust can add to a Mustang GT (which is to say a bunch - probably 0.4 in the 1/4-mile easy), I'm pretty sure 392 owners will walk a stock GT unless they totally blow the launch. I'm not saying it will be a cake walk -but it should be a win.

Another way to look at it - wait until 392Pusher adds a CAI, exhaust, and a Diablo tuner (or better yet a CRM tune) - and let's have a re-run of that same race against a similarly modded GT. Game over.

I'm a big Mustang fan too - respect the heck out of Ford for bringing the best bang for the buck on the domestic performance front and the Coyote 5.0 is one hella strong engine. As an side, I am a little peeved all the car magazines are rating the Boss 302 at 444 HP with the TracKey enabled though - it's 490 HP. I think C&D is the only one who tested it off and it ran 12.7 (right where it should be) and everyone else is running 12.3 with it enabled. Big difference - basically like adding a tuner.

Ford is charging $302 for the TracKey mode, and I think Dodge should respond with a $392 track tune for the 392 Hemi. There is a lot of untapped potential in that engine and I'm sure Diablo and CRM will eventually demonstrate.

Yep, could have and didnt. By the way, my buddy has a new manual 5.0 with custom tune, CAI and exhaust. He is putting down 417rwhp and 405rwtq with no bottle and makes well over 500 with the 75 shot. I know once he finds out I have a new 392 he will want to run me. Unfortunately he runs 12.40's @ 119 with the above mods on the STOCK TIRES without the bottle.

If you get CAI, LTs, exhaust, and a CRM tune then it will be a fair fight. Until then you will be bringing a knife to a gun fight. If you do make those mods and run him, make sure he pulls the bottle so he's not tempted to tickle the juice when you start walking him.
