2011 Mustang V6...motor rated at 305hp...to verify they put it on a dynojet. 308rwhp...s***. There's no way that it made almost as much hp to the wheels than a 2010 GT's motor is rated at.

[Razi]

Why do you think that's impossible?
Many v6s make around 300hp.

[MellowZ32]

[vikesfankevin1986]

I'm not hating...I kinda want one. But correct me if I am wrong...When they advertise a motor being rated at 305hp that is at the crank. At the wheels it should be around 260. If they made 308 to the wheels, the MOTOR would be rated at around 360 or so...right? To verify if the motor is really rated at 305hp, you wouldn't stick it on a dyno.

300hp or 300rwhp?

[simmode1]

Why not? Didn't the auto industry call for changes in horsepower ratings a few years ago? I thought I remember reading that they were gonna start publishing their hp at the wheels as opposed to their power at the crank...

Plus, they used the K&N Airfilter dyno... isn't that the same dyno the SCC and Modified Magazine have used for years in the USCC and Tuner Car Shootouts?

I agree though, it is a little hard to believe. Those numbers in the video might be the variable corrected figures.

[AppleBonker]

Or they're underrating it to avoid cannibalizing the GT and up sales...

So my friends 2010 GT rated at 315hp only made 325rwhp after intake, exhaust, straight pipe headers and cams? All that stuff only gave him 10hp?

[vikesfankevin1986]

Did find this...

and this...
http://www.youtube.com/watch?v=418g2F_Q5dg

First one is a 2011 V6 racing a 2010 GT. Close race...one being rated at 315hp and the other being rated at 305hp, that makes sense.

The second video is a V6 dyno. He said it makes 260rwhp. That sounds about right.
I beat my friends 2010 GT with intake, exhaust, straight pipe headers and cams. I have catback exhaust, CAI, DPs, JWT ECU 12.5 psi and light weight flywheel.
I am going with they probably make 260rwhp. And I'm not hating, I'm being realistic.

[Razi]

I believe there have been changes made to the way HP figures are published now, it's measured at the wheels rather than the crank.

s*** son...Ford is notorious for underrating their motors...

Z guys help me out...My Z was rated at 305hp...a stock Z makes about 260rwhp...My car has been dyno'd as high as 305rwhp and as low as 284rwhp. Yet I beat my friends GT? I also beat a 2010 Dodge Challenger RT (rated at 375hp.) So I am I the greatest driver of all times and I have some kind of miracle car?

Kinda, but it's disadvantage is that it's a lead sled, thing weighs a ton.

Hell if I know.
Did you dyno it before all those modifications?
What the car maker published and what the car actually makes on a dyno will vary.

[hvp014]

Your comparing the 2010 to the 2011

Ford up'd all the mustangs engines for 2011.
Including brining back the 5.0L which makes around 415 WHP.
http://jalopnik.com/5429269/five+oh-201 ... 0+liter-v8

And what the 370z, which is a 3.7L same as the mustang v6 makes what 330WHP now?

So their on the same playing field, I think were all stuck in the mentality that v6 mustangs suck. Which now they don't.

[vikesfankevin1986]

You know I really wish I wouldn't have posted this. I spend a ton of time on Mustang forums and unless someone can show me that they measure hp at the wheels and not the crank, I think you guys are on crack. Do you know how many times I have seen the question "how can I get 300rwhp?" in the Mustang forums? IF MUSTANGS ARE RATED AT OVER 300HP WHY WOULD THEY NEED TO GET THERE? Do Mustang owners not know anything about their cars? Are they using some kind of dyno we have never heard of?

I think the V6 Mustangs are amazing. 2011 GTs DO NOT make over 400rwhp without a tune. 370Zs make under 300 rwhp stock.

[AZ89two4Tsx]

None of this stuff is accurate at all.

The only way to prove it is to get them ALL on the SAME dyno. Specualtion, specification, and "I beat this,I beat that" does nothing except misinform.

Every dyno result I have ever seen for a stock 2010 Mustang GT is right around 270rwhp. That clearly exceeds their 315hp rating doesn't it?

Yea you are right. A race from a roll is not an accurate measure of car performance

[Mr1der]

Kinda, but it's disadvantage is that it's a lead sled, thing weighs a ton.

your Altima is right there in the same ball park with it weight wise.

the Mustang should come in around 3600lbs.

[vikesfankevin1986]

A total of seven pulls were done with the final few runs laying down 395-hp at 6600 rpm and 365 ft-lbs of torque at 4350 rpm. InsideLine claims that due to the solid rear axle the ‘Stang will only see a drivetrain loss of roughly 11 to 13 percent power. And it doesn’t take a calculator to figure out that the 17-hp difference between the claimed flywheel number and the dynoed wheel horsepower number is far less than that. So what gives? Well, there are two possibilities. The first is that the pre-production models are pumping out more power than stock. The second option is that Ford has underrated the car’s 412-hp number – always a smart move.

Normally a car with 412-hp would lay down numbers closer to 360 whp. Instead, with 395 tested whp, it looks like the new 5.0 ‘Stang makes closer to 440-hp. Not bad!

That is from here...

See boys and girls...The Mustang IS UNDERRATED but is still rated by CRANK hp.

It isn't.

It's going in a straight line and THAT'S IT. Even from a stop it would be better.

You're retarded. Quit posting and keep street racing BRO.

[Mr1der]

racing from a roll is the weakest s*** I've ever seen.

it's for idiots that can't launch off a tree.

as for the topic, go and research Ford under rating their motors.

the only one I can ever remember them overrating was the '98 Cobra.

[vikesfankevin1986]

Hey guys we need to tell all the guys at the strip to stop racing. Racing in a straight line tells us nothing. Pull your cars off the strip and go find a dyno. Maybe we should let the experts know that when they test 0-60 times and 1/4 mile times they need to be on curves or on a dyno.

You don't know the first thing about me retard. You assume I f*** run around looking for street races. Where did I even say I was street racing? How do you know this wasn't at a track or a strip? Don't assume you know me BRO.

Since I need to tell my life story, I will. The only roll race I did was against my friends GT. I have actually not raced many cars at all. The challenger I raced was from a stop. The reason I raced from a roll is I had just got a new clutch and new clutch line. The clutch felt very different. I cannot launch with my new clutch yet and I don't want to try considering you need to break in a clutch. I don't want to break the thing to prove a point.
