2004 3.9L V6 Mustang on Dyno

[caleb20091]

yes because like every car there reading you numbers from the crank not the rw my 02 gt stock pulles 220 rw with my bolt ons i have 260 ans thats dynotune headers full exhaust throttle body

[tpvalley]

a 3.9 should have at least 250bhp?

[Elmo187]

@tpvalley Engine displacement doesn't constitute power.

@Elmo187

Thats not really what I am saying, I am saying that a 3.9 litre engine with only 160bhp is fairly low tuned; even the torque isn't that great.

[Lochinvar111]

From what I've been told the early '04s had 3.8 V6 engines and the later '04s had 3.9 V6 engines...

[killepilot]

nice but why u say 3.9L is a 3.8L and doesnt matter if is tunned is a 3.8L tunned

[mandrgalvan]

because the 04 v6 mustangs were 3.9L

[Nagakilo]

In 2004 they added .1 liters. So he correctly labeled it.

[kickflipdemon]

yea i have one of the 2004 and on the hood sticker it says 3.9

[raul9505]

how big was the difference?? with 7more hp aprox?

[AoDLongbow]

@raul9505

yes about 7 hp to make it an even 200 at the crank instead of 193 like the 3.8

[smiley00341]

what do you run in the 1/4 mile

[mandrgalvan]

Auto or Stick?

[sctlivewire]

sweet me and my mom has 400hp in r 3.8l mustang. u should add some power adders

[PeteyPolo73]

I'm assuming thats stock except the exhaust.

Is it normal for there to be a 23 horsepower discrepancy between stock stats from ford and actual dyno results?

[tjames57]

that HP is to the wheels. the stock HP is measured at the crank. so 190 HP to the crank and around 163 or so to the wheels stock because of paristhetic loss. so 169 is pretty good for only having exhaust and a CAI with no tune

[PeteyPolo73]

oh, thanks alot.

[pahsons]

HP has not been measured at the crank since the gas crisis of the 70s

[immortalwearsd]

169 hp at 3rd or 4th gear?

[blknismo180]

this was urs i think?
