2004YellowStang

I have a 2004 Mustang I just got with the 3.9L V-6. I was just curious what the stock horsepower/torque ratings were at the crank?

Also would a MAC cold air intake and a GT takeoff with a magnaflow cat back be a good place to start for mods? Roughly how much real world horsepower should that net me?

193 hp/ 225 tq...I'd tell you more right now but I'm bout to fall asleep...

specs are the same for the 3.8, A CAI and an exhaust, would probably give you 10 rwhp at the most, i would say go with flowmasters though. You might be able to get a little bit more if you dont do GT take-offs and get an actual exhaust system.

There is no 3.9L V6......

NewMexMustang

yeah, the specs are the same as the 3.8 except that the 3.9 has ~5 more lb-ft torque.
Yes there are 3.9L

I guess I thought it had a little more power than that, the salesman lied to me! *GASP*. He told me it had around 260hp..... Oh well, it still has some get up and go to it regardless of HP ratings.

And as far as the exhaust I found a kit on some website that has the true dual conversion for the V-6 so you can run a aftermarket GT exhaust. That's what I was planning on doing. Although I'm not sure what brand to get, I just want to make sure it's all stainless steel.

260? hahahahaha...im sorry but you got HOSED man...if you dont mind me asking...i hope he didnt charge you as much as a GT would have been.
