Innovate LM-2

Remember Armo he is really stock so he is pretty close to normal but for sure you can not Dyno in 5th gear.That's a loooong pull with lots of blower heat generating so has to be in 4th and "M" mode.

ND to make a 100-200 pull on the Dyno or street ? No way there should be a "normal" Dyno run up to 200mph unless you planned on running that high on the street " Germany" or the track.

@SICAMG 100-200 on the street, and I mean in kph (kilometers per hour) Would be great if we can convert USA to metric system haha

I dont think this has been done

The dynorun. Last part of the video is dark, because I filmed with my phone with stabilisation turned on

SICAMG

Those pulls are way too long. They are probably in fifth....not good.
But sill I think it's pretty good.

nd-photo.nl

That was also my feeling when I looked back at the footage, they are quite long

UncleBenz55

Why is the dyno louder than the car though?

nd-photo.nl

I have no idea

SICAMG

I could show you my 4th gear pull so you can see the time difference but don't want to hijack your thread.

nd-photo.nl

@SICAMG I think thats valuable to the discussion, so please post it

SICAMG

Just to give you some insight this run picked up 75hp and 80lb's of torque in the mid range and 35hp up top from just a timing change and some leaning out with the fuel pressure regulator with the AFR from back to back Dyno runs.
For years I was running the same timing as I was told it was safe so even after many tunes with changes only in AFR I took a big step in a total timing remap and was rewarded big time.
Last week I went to the track and this tune gave me an official 156mph and 162mph running the car out further past the finish line. That's 6 mph over my best last year so moral of the story......tuning tuning tuning !!!
I believe every car has lots more power locked up in it and I am sure yours,and it runs good making those numbers, does too. Dyno again in 4th gear and log your runs for sure.
Remember too that more power always makes for a faster pull.

nd-photo.nl

That run sounds way different than my run...Also a lot shorter

UncleBenz55

Mine was also measured in 4th gear and max rev was 6700rpm

nd-photo.nl

Same comment, sounds different

Sulaco

If it makes you feel better mine has relatively aggressive mods with a 72mm pulley, full exhaust, cooling upgrades, and only put down 435 rwhp on a Mustang dyno that's famous for breaking hearts.

but performance on the street indicates the thing is stupid fast. on the highway its nearly hellcat fast.

nd-photo.nl

@Sulaco I would be happy if my dynorun said 435 rwhp haha. The reason for this thread is understanding where this low power figure was coming from

I have read more often that the mustang dynos are quite conservative with the power figures

SICAMG

ND I will say it again your numbers are pretty good. That's way over 500 at the flywheel on just a tune so to me it's a great start and you can work from there.
Plus since it's so strong from the start just imagine throwing a pulley on and headers...will be 500 for sure !!

nd-photo.nl

I know the car is more powerful than what was measured

With regards to your signature, can you keep the front cats with midsize pipes?

SICAMG

Yes you can. It requires cutting the mid pipe collector shorter and adding a larger/different down pipe to the cats. Then you can stay legal and no one will know anything was done.
It will take some time to get it all lined up but the cats will almost be right where they were from the factory.

cannot compare dyno's of different manufactures. use of the same dyno before and after modifications is the only way to compare, but must not compare numbers against other people's dyno's on another dyno manufacturer.

for example, some dynos on that side of the world are a rolling wheel dyno, but report out on crank power output which makes no sense. literally, reporting the crank output after you've loaded up the wheels on a rolling dyno and using the power at the wheels with conversion factor. not the say measurement as an engine dyno which outputs crank output.

nd-photo.nl

@eightysixtuned I'm aware of that, I just wanted to make sure that I'm not taking crazy pills. Again: I would expect that my dyno run would be at least in the ballpark of other experiences on here. But I think we have confirmed by now something in the measurement was off (operator error).

In summary:
Dyno reported 457bhp (at 5300rpm) at the crank (which is 20hp less than stock)
Dyno reported 717Nm (at 3400rpm) at the crank (which seems spot on)
Dyno report shows 356bhp at the wheels (which is way too low, should be above 400 rwhp)
My Dragy 100-200 kilometers per hour measurement of 8.99 sec corresponds with a stage 1 E55/CLS55
I raced a buddy with a CLS55 Stage 1 and we 100% even in a 2nd>3rd gear pull

In other words: there is nothing wrong with the car, but the measurement was done wrongfully (high probability: 5th gear instead of 4th gear pull combined with some heat soak)

eightysixtuned

so dyno gear selection only has impact for inertia dyno's like a dynojet or other non-clinical dynos. loaded dyno's like a Mustang Dyno, DynoDynamics, Dynapack, etc should not be impacted.

if numbers are a concern, i'd recommend seeking out a dyno of which they have other M113k engines in their database of which you can compare with. one thing also to mention is, sometimes, if a dyno machine has had its firmware updated to a newer firmware, dyno reading and output can change as well so post firmware and pre firmware dyno's may no longer be feasible for accuracy's sake.

SICAMG

I know my numbers are very close because other cars at the track at the same weight and horse power run around the same mph.
Although transmissions play a role along with torque curves and areo dynamics but it's pretty close non the less.
Also don't get cought up in numbers so much. It's a double edge sword...kinda like going on a diet and staying off the scale. You still need to know where you started moving forward and use it as a tool.

OP -

Just wait for the winter months, you will feel like you added a couple pulleys and/or headers to the car.

nd-photo.nl

Its already getting colder, but that also means less grip I swapped my 20" lightweight wheels to my 19" AMG wheels again, to save some thread for next spring & summer. The 19" AMG wheels also have summer tyres on them

Again, the car is fine, it's more that the run did not meet my expectation

SICAMG

It always amazes me how different the weather can play a roll with horse power and now I will ONLY race in the cooler weather and that's it.

Back in my Buick Grand National days ....in the heat of the summer with the AC on the car was an absolute turd after an hour of driving but winter...woo hoo !! LOL
