2011 Gt First rwhp dyno test

[06GTMustang89]

If you bother reading the article they have pics of the engine bay and it is stock...

I did read the article...someone can easily take a picture of the engine..then switch something out then take a video from the rear so no one can see...

Your taking it as im putting it down...im just being realistic...it is impossible for a production car like ours to have 4% drivetrain loss...unless like mentioned above it is underrated at 412 at the crank...

dont believe everything you read, and only half of what you see! lol
i HOPE its real, but smells a tad fishy to me.

 

[07TGGT]

Yes because Ford Racing already made a CAI for the 5.0 that hasn't even hit showroom floors yet...

 

[bolivianpimp]

Wow it almost seems too good to be true! Stangs will run the streets !

you just said it right there...now the 395rwhp is believable if they used that... joke..

We will have to wait and see if those numbers are true i hope they are...but don't be surprised if they aren't...

 

[07TGGT]

I hope you caught the sarcasm

 

[Vapour Trails]

I'm not buying it. That would equate to 464 chp and 93 hp/L. I suspect a generous dyno.

 

[06GTMustang89]

i really hope you caught mine since i said "joke" right next to it....

 

[DDTCM]

I doubt its underated.The only reason they underated the Terms IMO is because everyone that bought a 99 Cobra including myself got.....for lack of better words.....Fucked on HP and had to do the recall plan.Im just not seeing 395.

 

[KrisR]

I hope it's true.

Seems a little high, but even the 4.6 3vs are underrated...mine made 275rwhp stock on a Dynojet, which is obviously a lot more than the 240-255rwhp it 'should' have made assuming 15-20% driveline loss.

 

[ArizonaGT]

4th gear pull, this is not 1:1, numbers are inflated

Right,I gotcha but every one is gonna be different.I was not happy after adding Kooks lts,catted H,cai and tune and only seeing 297WHP after 2 pulls on my S197.But it was a group dyno day so they were blowing through cars in under 5 min a piece.

if you did back-to-back pulls, you are probably looking at heat soak for low numbers. probably not as bad as you think

 

[Greg Hazlett]

Heat soak on a N/A engine??? I can see that on a FI car but not so much on N/A.

I already posted i was suspicious it was underated. The lead powertrain engineer stated it had over 100% VE through 6500 rpm.

390 lb-ft of torque at 110% VE

Over 100% VE at 6500 rpm according to the lead powertrain engineer.
Assuming 100% VE that equates to roughly 355 lb-ft of torque.

355 lb-ft x 6500 / 5252 = 439 bhp

439 bhp x .88 = 386 rwhp.

412 bhp would only be 333 lb-ft or roughly 94% VE so either they are under-rating the engine or making incorrect statements about the VE.

Disclaimer: This is an Oversimplification but you get the point of why I suspect something is up.

4th gear pull, this is not 1:1, numbers are inflated

Actually when you pull in a lower gear it reduces the horsepower figure. Just like higher numerical rear gears.

 

[Dr Wu]

Was the 412 HP an SAE certified rating by Ford?

 

[Gene K]

If your talking about the new 2005 test I dont know. I would assume so as Ford is supposedly using that test.

I still want to know how it could only make 412 bhp @ 6500 rpm at over 100% VE.

 

[STACYSTANGZ]

I have heard by a reliable source that this is a pre-production 2011, meaning the #s will not count.

Here is a link to another Edmund video involving Dynos. They take a 2010 GT500 540HP, and it puts down 511RWHP stock. Which seems high as well

It looks like the same dyno to me. Dyno could be very generous

What he said. If it were to be dynoed it 5th, the numbers would be slightly higher
