Buddy filmed his night at the track w/ his 05 Mustang v6 auto w/ intake/ tune/ exhaust <duals and single have dynoed the same gain>. Oh, and an underdrive pulley also that dynoed at 0 gain, lol. Tracks at sea level, temp was about 84-86 degress, humidity 65%.

No, thats not a GT, he just has GT takeoff parts from Saleen, you can tell it's a six by the back emblem, GT has "GT" in the middle of it, six has a tri-bar pony.

Cool. Are people building up the V6s up engine wise? (e.g. cams, turbo/supercharger, internals)

jercho73

Yeah, this engine takes to mods very well...the first turbo 4.0 on mustangforums is running low 13's consistently, at just 8.5 psi and that's also with an auto. Auto is actually better then 5-sp for f/i as it uses the same tranny as the auto GT, and thus can handle alot more power. The v6 and GT manual trannies are different.

rhythmnsmoke

interesting, was he manually shifting the Auto Tranny?

jercho73

It's a straight 5-speed auto, no shiftstick or whatever. I assume you ask because he chirped 2nd and 3rd, depending which tune you run it firms up the shift points enough that the auto does that.

I didn't know that. That's pretty sweet

rhythmnsmoke

Sorry, that was me talking. Somehow it switches to my fiances screen name.

Ford needs to learn how to make an engine.

jercho73

Um, ok? The engine is made in Cologne, Germany, not a US Ford plant.

jercho73

You're turboed? Cool, what kinda times do turboed Tc's run?

RollTide

Out of curiosity, does the German plant design and tune them as well? Seems to me that the Germans could extract substantially more power from 4.0L than 210bph. What gives?

rhythmnsmoke

Depends on which turbo manufacture you go with. ZPI tC's will do low 13's high 12's on a Stage 1. Every other turbo kit out is like a Mid 13. The only tC's that are street driven and the fastest on the track come from ZPI.

Subcompact Culture

Ford doesn't want to make the 4.0 outperform its V8. That's probably one reason.

Plus, look at Scion. I'm sure they could get more power out of 2.4 liters on a tC.

There's a lot of aspects to look at than just how a company can tweak the hell out of an engine to produce a buttload of power. Fuel economy, other models in the lineup, drivability, etc. I'd bet 99% of Mustang V6 owners are fine with that much power. Others will opt for the GT.

jercho73

The 4.0 engine is detuned from the factory, for both emissions and marketing reasons, which is why a simple tuner/ cai combo can add 25-30 rwhp, or a simple axleback 12-15.

jercho73

Exactly, people are always asking on mustangforms or whatever forum why the 4.0 has so much worse factory specs then say Nissan's 3.5 stable. Those of us who had imports are always explaining most import cars are well tuned from the factory, the Mustang isn't...for the reasons you mentioned, like you said most v6 owners are happy with 210 chp, the ones that aren't are happy to have the room for decent gains

jercho73

Very interesting, and great numbers...high 12's are roughly what the one turbo Mustang v6 i've seen was dialing in. Superchargers are alot more populer for the Mustang, quite a few of those.

What PSI is the turbo at to give those numbers? What kind of power can the Tc hold before you have to start upgrading the internals?

rhythmnsmoke

@ 8-9 PSI you can expect those times on the ZPI kit. I don't know about the other kits, but most if not all the kits come off the shelf with a 8ish PSI setting. I have seen as much as 400+ being held on the stock motor. Not adviseable by any means. Most agree that once you approach the 350whp mark, then think about internalls, or it bye bye motor.
