Pacettr, the educated s197forums troll. :naughty1:

Yeah, I'm as much a troll as you are. Really?

Figures you would start another internet fight :stooges: I was headed towards the Kuro spot but your in the lead..haha


dynos dont lie..

What do you see at 4175rpm? It looks like 310-320hp to me.

So SEER is convinced it "looks like" 305, you think it "looks like" 310-320, I KNOW it is a computer that uses a mathematical formula that says if engine X makes 427 ft/lbs it makes 339 hp at the same rpm.

To argue otherwise is foolish.


To argue that the dyno might be "happy" is not a stretch.

happy by giving him about 50rwtq over most other 5.0s with similar mods...happy is an under statement. But keeping HP in line, hmm.

That's where you show your naivety. Its obviously not 339HP at 4175rpm.

LOL


In most dynamometers power (P) is not measured directly; it must be calculated from torque (τ) and angular velocity (ω) values or force (F) and linear velocity (v):
or

where
P is the power in watts
τ is the torque in newton metres
ω is the angular velocity in radians per second
F is the force in newtons
v is the linear velocity in metres per second
Division by a conversion constant may be required depending on the units of measure used.

For imperial units,


where
Php is the power in horsepower
τlb·ft is the torque in pound-feet
ωRPM is the rotational velocity in revolutions per minute




As I have stated, even if the dyno is reading the tq high, dynos don't measure hp, they CALCULATE IT. Unless Dynocom uses a different formula than the one from physics class, the respective hp/tq values HAVE TO BE ACCURATE, at least relative to each other.

and this dyno did not measure or scale either properly. I've shown you where you're wrong, and you keep beating your head against the wall.

Now I am going to be irrational here for a second. If S197 GT's car is making an equal amount of HP and torque at their peak figures, then he has a rare car. It should be sold back to Ford as an engineering sample, as he is the only reported case of this ever happening in existance.

You have SHOWN NOTHING. You have GUESSED at what you THINK it LOOKS LIKE. I am using FACT. :highfive:

No you haven't. You're the only one here with your opinion. If a tach read isn't placed on the car properly, or comes loose that alone can cause the torque figure to miscalculate throwing off the entire run.

All you're doing is quoting equations you don't even understand from wikipedia lol.

When others have broken down this dyno run apart and have all chalked it up to an error on the dyno. Get over it, it happens. Even if the dyno showed him making 650hp/655tq, the ratio of the peaks is incorrect.

You're not using any kind of fact, all you are doing is taking a bad/unvalidated number and using it as your constant. I'm glad you're not in any type of engineering field.

This could go on for days. :chairfall:

I'm holding back what I do for a living and throwing out the advanced degree card (hint, all of my degrees are in engineering and fields that require advanced mathematics). I've learned how to spot when a measuring tool fails by trend analysis.

I'd rather keep it civil but I'm at the point I don't care what pace says about the dyno. Some people just don't understand.

It just seemed off to me just from shear fact one of the ducks is not like the other concept.

Also pacettr, don't take offense i was just fucking with you. :highfive: You seem(ed) flustered.

I'm going to go with Indian for $500 Alex:highfive:


As a full blooded descendant from Europe (France, Spain, Italy), yes I am white American, I resent that shit. I kicked those stereotypes (Asian and Indian), in almost every engineering class I took...including graduate school. Graduate school was the worse shit. They tried bumming answers from us, to make themselves look good.

I was pretty much the only American born in my doctoral program at my school.
