"Official" hp and torque numbers have not been released by Ford yet. Those are the projected numbers that have been out there for awhile now.

According to this. 2.3 EB will get more than 310 HP and max torque from 1500 RPM.

 

[86GT]

I'm going to guess the 2.3 EB ends up making 325hp/325ftlb. I also expect a 13.5 @ 104.5 mph in the 1/4

I'm down with that. What's interesting with these motors now that i've seen dyno figures on somewhat similar new engine offerings from bmw/vw after being tuned out is that usually it appears like their can be alot more torque massaged out than horsepower.

yeah go check out some dynos for the Focus ST. The torque gains are huge with just a tune. I won't be too shocked if bolt-on 2.3EB cars make similar torque to the 11-14 5.0

 

[DivineStrike]

Honestly it will probably make more tq than the V8. A tune and turboback exhaust on my 2.0 GTI increased tq by over a 100tq. Stock specs were 200bhp/207tq. With tune and exhaust 270bhp/320tq (using a 15% drive-train loss in relation to the dyno). On a mustang dyno it got 232whp and 280wtq.

Looks like an equivalently modded st (with my gti minus the intercooler) got 240whp and 353wtq and it's still only a 2.0. Also looks like it's got a bigger turbo than my GTI. Looks to me though like they should have gotten more power out of all that if stock is 253bhp. So bhp/tq adjusted at 15% drive-train loss is 282bhp and a whopping 415tq!

Yeah I can't believe how much torque these little motors make.

 

[S550Boss]

The ST has a tiny turbo, as does the 2.3 EB fort the Mustang. That will be the ultimate limiting factor. Tuners like Cobb will get a bit more HP, a lot more torque, but even then the turbo will quickly need replacing. And it won't be cheap.
The next limitation is the injectors. Mountune sells a replacement set - and tune - in Europe. Cobb isn't that far along yet.

The Mustang specs are probably very close to being published: the other user of the 2.3, the new Lincoln MKC, makes 285 horsepower and 305 lb.-ft. of torque.

BTW, here are 31 super high resolution pics, allowing you to see each part of the Mustang 2.3 EB engine in very high resolution. Most of the pics are over 5000px wide.

2.3eb in Mustang will be 310hp/312ft-lbs of TQ @1500 ~

That'll be a little disappointing if true. I was really hoping for at least 320/320, if only to further separate it from the 3.7

It shouldn't be disappointing. A turbo 2.3 Ecoboost at 310/310 would feel completely different than the N/A 3.7 V6 at the exact same power and torque. The turbo will bring the torque in much earlier and will feel more powerful not to mention have more power on tap with a competent tune.

How much torque does a coyote have at 1500 rpms?

How much torque does a coyote have at 1500 rpms?

It's difficult to find definitive specs on this as most dyno data doesn't start until at least 2000 rpm. But I did see some results that seem to indicate that a stock current gen Coyote makes ~250lb-ft at 1500 rpm. 300lb-ft isn't reached until somewhere between 2250-2500 rpm. So at low rpms the ecoboost will probably actually have more grunt than a current-gen 5.0.

Obviously it remains to be seen how the changes to the motor and tuning in the S550 will affect the GT in this regard. I personally predict that it will be a bit better than the current 5.0, but still not quite as good as the ecoboost.

I mean, I know that, and enthusiasts know that, but I'm not sure the general public will understand it. I'm really hoping the 2.3EB takes off and sells a ton, and a higher power difference would hopefully help that happen.
