I think for horsepower it is about 267-270 at the wheels for an auto, and about 273-275 for a standard, don't quote me on that but that is what i have read. Jord

255-260whp for Automatics
260-265whp for Standards

There are always factory freaks that will put down 270+whp.

I've heard 255-265, every car is different..

+1 around the 250 to 265 mark!

I've seen a couple go 240ish.

~260 rwhp for manuals. ~ 250 rwhp for automatics.

My mustang club did a dyno day and the 05+ ranged from 254rwhp to 269rwhp. remember the older the engine gets the less it puts down adn also somehthing as small as an oil change can add 3-5hp

I have to disagree since I've seen so many cars on the dyno. Just my 2008 Mustang has been made about 30 dyno pulls. I've never seen a stock 05+ Mustang put down 269 rwhp. I do not believe in factory freaks, it just doesn't happen anymore. The tolerances are so tight now a days that it just doesn't happen. Motors do not put down less hp as time goes on unless you're talking 100,000-150,000+ miles. Also no oil change is going to give you 3-5 rwhp. Remember that every dyno pull is not completely accurate. So many vaiables are at play that it is just simply not a controlled environment.

I have seen a STOCK 2007 5sp GT put down 269 on the same day and same dyno as another 06 spd GT put down 257hp. This was a mustang dynoat Murrillo motorsports in SA, TX.I know that the dyno is not always 100% accurate because every pull i have down is always 2-4hp difference. Also the thing about the oil has been proven i have seen it done. And i also think Royal purple has done it before.
