people abused it..... Admin got tired of the crap
Dynos measure power. I've stated it a few times. Without gear ratio information the only torque measurements it can spit out is tire torque which is after a gearbox's effects on torque. This is why a tach signal is important for correct torque measurements. Its needed to dropout gearbox ratios from the torque calculation.
Let me ask you a related question which I'm feeling has a lot to do with why you aren't understanding this.
Without using google, what do these three equations equal?
(moment of inertia) x (angular acceleration) = ?
(torque) x (angular velocity) = ?
(torque) x (angular distance) = ?
Also, you don't need a 1:1 gear ratio to get accurate numbers. Thats another myth thats derived from dynoing automatic transmissions but thats for another day. I simply used them to make it clearer to understand rear gear ratio's effect's on tire torque and to avoid the 1:1 myth from coming up.
With a brake dynamometer, the torque that the wheel applies to the drum is found more directly by applying a regulated counter-torque, using transducers to measure the braking force, which must be calibrated and which can be a significant source of error if not done properly with a good understanding of metric processes.
As far as I know with Mustang and Dynocoms, its still recording a unit of power by measuring the force it takes to hold the roller in a steady state vs. roller speed, great for tuning Speed Density cars. When he mentions measuring force you have to assume the roller speed in also a factor in the equation.Couple of questions, attempting to remain technical and engage in relevant discussion...
If I am reading this right, a brake dyno (like the Dynocom used in the dyno graph being discussed) actually measures torque (force) and if calibrated improperly would yield inaccurate readings (i.e. a bolt-on 5.0 making 425 rwtq).
And on an inertia dyno, gears etc don't matter because it is measuring work over time, i.e. 1st gear 0-30 mph in 3 sec ~ 5th gear 60-120 in 6 sec for example?
Ya, wtf happened to that? When I first registered I could have sworn it was active but haven't posted here again until recently and notice its not.
Man, that was the longest dyno pull ever... LOL J/K
A little birdy told me the OP is running around with a stock tune now. The engine didn't blow.
Dead serious, the OP is local to me.
that's hot.
Googling more catfight pics now.
Well fuck OP for throwing a big hitter down under the bus when he never even blew the motor!
Lastly, to simplify, "Horsepower is what torque does".
This guy is a new member on another forum I am on and never posted this over there. He also owns a New Edge GT....not a 2011, so why would he even post this. He has recently disappeared from our site also.
He is an active member on svtperformance, and it does look like he owns a 2011 also. The new edge is his build car, the 5.0 is his driver.
I don't think he was trying to mislead anyone, probably wasn't expecting all of the attention.
He also needs to publicly tell Jon Lund he is sorry for starting this shitstorm.
