My stock 1M on a Mustang Dyno

[pearlwhites]

Hey Folks,

So I dyno'd my stock 1M today and came up with some impressive results (especially for a Mustang Dynamometer) that I thought I'd share.

I did 2 runs while monitoring AFR/boost manifold pressure. The first run was without the M-button pressed. The second run was with the M-button pressed. As you can see both runs are nearly identical hp/tq/AFR/PSI wise, so I think that's a bit more evidence that the M-button is good for gaining up throttle and little more. Another interesting note was that the shop owner recently tested a stock 335is on the same dyno and was shocked to see that I made 40 whp more than the other car. The assumption was that the two tunes were exactly alike... I guess not.

For those too lazy to look at the graph: 340 whp and 400 lb/ft were the average of the 2 runs with peak boost of 12.6 PSI and min/max AFR of 11.5/18.9.

Seems like this mustang dyno was reading at 12% drivetrain loss, normally mustangs are within 12-15% loss. Dynojet is 10% so thats why your seeing numbers close to a dynojet, because its only a 12% loss not 15%.

Sorry 1rider I'm a bit lost. How do we know what drivetrain loss the dyno was reading? Is that 12% based on what other 1Ms are putting down?

Excellent results, are you going to be modding your 1M?

+1 How do you know this M///1rider?? Maybe I'm blind but I don't see anything that would suggest this.

Even considering this he's still laying down around 385 whp and 450 wtq which is nuts

Nice dyno btw pearlwhites.

That wheel tq is kind of surprisingly high. Tuned 1M's are only in the 400-450 range...

Thats what i was thinking...450 for stock is nuts!!!

Is this what people are normally seeing with stock 1Ms, or is this a factory freak?

[RnmEvo9]

It could be a high reading Mustang dyno (they are all not the same). The important thing is, that he has a baseline and that if he should start modding the car, he will see exactly what he is gaining granted he goes to the same dyno again.

The dyno seems suspect to me especially for the low max boost numbers. The only way to validate is to have another 1M do some pulls on the same dyno. Are the numbers SAE adjusted?

Practically your "stock" 1M is putting down 380+ hp and 600+ nm flywheel, though good news they seem really high; the other dynos I recall in this Forum were in avarage closer to 360 hp and 550 nm torque.

Also that much difference from a 335is is interesting.

Other than a possible high reading dyno or a freak engine from factory, could you tell us what type of fuel was used?

Sorry i meant to say this must be reading at 12% drivetrain loss.

Dyno jets are normally 10% so they read the highest,

Dyno dynamics normally read 18% so there the lowest.

Mustangs are normally in the 12-15% range and seeing how high your numbers are id say it was a Mustang dyno at 12% drive train loss.

And no he is not 380 whp he is 380 crank hp. About 440 crank torque as well.

All in all very nice numbers!

380 crank hp not wheel 445 crank torque. !!!

Sunoco 93 octane.

Yeah we were all surprised by the tq numbers. Dyno owner said it dyno'd higher than many jb4 cars he has run. It was a cool 57 degrees F that day and other than the cool air, the car is 100% stock.

I'm in NYC if you are interested maybe would could compare our cars.

yea i also saw a stock tune on a full exhaust car, he made 350 wheel and 380 wtq, the tq loseis because it does not have a tune but it its still putting down the same amount as a jb4 map 2 which runs 14.5 psi, the thing about the 1ms tune is it boost very high in the midrange, i dynoed 450 wheel tq which is what a jb4 meth would do and thats because my boost numbers in the mid range. im boosting 17.7 psi midrange which is equal to a jb4 meth boosting 17-18 psi

but it tapers to a jb4 map two boost down to 14psi around high rpms

if you all understand how im putting this together you will understand haha

I'd be happy to, unfortunately I'm over 6 hrs away from NYC.
