there are 3 of them there the 1st is the first run on a loaded mustang dyno, the 2nd is another loaded run on a mustang dyno and the third is an unloaded dyno on a mustang dyno. enjoy.

 

What were the numbers they are kinda hard to see.

 

why such a difference between 1st and second runs

 

first run is pretty good for an auto, 2nd and 3rd runs are a little low if im reading them right, numbers are hard to see

 

I think the higher number was the unloaded dyno run

 

what does loaded and unloaded mean?

I want get mine done on a dynojet.

Can you tell us the numbers--I can barely see the graphs.

 

The first two pulls were mustang dyno numbers, On the third pull were dyno jet numbers, thats why the one set is higher.

 

I can't really make out the numbers on those sheets. What gears were these done in?

 

1st run = 142whp / 126 wtq
2nd run = 144whp / 125 wtq

3rd run = 172 djhp / 147 djtq (dynojet)

i think the dynojet rates the whp but the rollers have no load on them like resistance like the normal mustang dyno does, i guess the mustang dyno adds resistance to simulate real raod conditions

 

1st and 2nd differance is due to the engine warming up and the fan being added to simulate the wind

 

these were all done in "L" gear from 35 to 65 mph

 

i can;t read the numbers, can u re post it bigger?

 

1st run = 142whp / 126 wtq
2nd run = 144whp / 125 wtq

3rd run = 172 djhp / 147 djtq (dynojet)

 

nice numbers.. 2.4 right?

 

yeah auto 2.4

 

nice

 

so the mustang dynos seem pretty realistic...that would add up to about 180ish crank hp

 

So when GM says the 2.4L has 171hp, which is it saying, the wheel hp or the flywheel hp? Which of these numbers above, ~143 hp ~172 hp does the car actually make on the road??

Why do we realy care about the flywheel hp? What we want to know is what it actually puts out while driving... on the road. So which is it??

 

on the road the car i think will be making 144whp / 125 wtq as celicacobalt said based on the loaded dyno

Those numbers seem pretty good for the mods he has and being an auto

 

good for the auto. The 5 speed should pck up a few hp and tq

 

Yeah, the man who dyno'd us said the 5 speed gained about 10 over auto.

 

pretty damn good, congrats.

 

all factory hp ratings are listed at the crank due to the different drivetrain losses associated with fwd, awd, rwd, auto, manual, etc.

in essence, no you really shouldn't be concerned with flywheel hp...there would be no point since its not being put down to the ground.

 

Nice numbers man!
