14% uplift ?  Does that make sense ?

 

[StealBlueSHO]

At 14% that would convert to ~340hp/436tq

 

[StealBlueSHO]

Which is about what others are putting down with AJPTurbo... slightly lower on the HP.. could have been heatsoak after the 160mph run...

 

[ajpturbo]

I would've guessed 360/460 since your spark was around 20 degrees in your logs...wonder what it was when you did your pulls

Hopefully you can run it at the track

I know they call mustang dynos heart breakers but why do they read so low?..stock numbers must be embarrassing

So if a stock sho put down 250 that would be like a 33% loss through the drivetrain...that is far from what people use as acceptable loss of 20% for automatic cars

 

[TopherSho]

Dynos are fun things, even running on the same type  dyno in two different places we can vary. 

340ish vs 360ish is less than 5% margin so it may be more or right on /shrug/

We ran 4th gear, had to compensate the roller resistance.. etc. 

1/4 mile NEXT WEEK will be very telling!

Heat soak you think?

Not sure which run they pulled the numbers from... these cars take forever to cool down...

 

[TopherSho]

It was pull 5 after failing in 5th twice and a recalibration run.

*But* the numbers under 5k were very similar.  Were within 5% so humidity, elevation, fuel quality, temp and circus mimes in Texas could have a cumulative effect.

For 92 octane.. as well and not 93.  So there is that too.

I mean. Really with fuZy napkin math were at 500ftlbs at the crank.  That is amazing for a family hauler

I am thinking it might be tied to the fact that he and I have CRAP options for fuel out here, highest anyplace around is 92octane, they have a habit of messing with it in the winter too...?

I am happy to see him put those numbers down with that in mind.  Crossing fingers, I woudl like to hit the 450 mark.

And here is the PDF...  Redacted the Plate and Name.

Nice...i like starting the pull lower so you can see when the power comes on...its impressive to see over 90% of your torque at 2500 rpm..it just spotlights where this motors shines.

And i think their afr sensor was calibrated for stoic of 14.64 for pure gas because your afr line is leaner than your data logs...stoic for e10 pump is about 14.08 so your afr is low 11's

Did they put it in the tail pipe? That could make it wrong to because of the cats

Wow yeah they did start it up in the rpm range.  I will make a note of that for when we get my tune dialed in and I do a Dyno run.  Pull from low as possible RPM and in 4th..

Topher - Did you run logging during the pulls?

Negative,  they had their HPTuner module hooked up.  I have the HP logs.. but i obviously cannot open them .

If you post those I am betting one of us can open them and post graphs maybe?  Tunes are usually locked up, but I think graphs can be shared..?  I have HPTune for my GM rigs and be willing to try opening them to share if you want.

Why would they have the HP device hooked up if you dont own a device and why would they stick an 02 sensor in the pipes if you have cats? Especially if they were logging with hp?

Any particular reason they hooked up the HP device to your car?

That's messed up...

Well the shop couldve at least gave you a free dyno session

No idea.  I *assume* to sync the rollers and the tail type enema ?  But i suspect mostly to get the HP graphs for highlights and possible sales points?

I attached the HP logs in a zip.. the forums rejected the file types.
