Ugh! I don't want to see that thing come over till it's gone on a diet. Bring on an all aluminium 4 valve version and then you've got me.

In the meantime I'll keep singing the praises of the 5.0. Unless anyone would care to send over the Fedex man with a worked 392w in a crate.;)

Yeah just wondering theres always this worry at the back of my mind, that the 5.4L might not have the muscle to match Gen III, what does everyone think. Whats everyone heard, i mean the Cobra R mustang has got 300kw out of it, can we get more power than that ie, 350kw+.

:confused: :confused:

I don't think we'll have to worry about that. I don't think we'll see power upto 350kw. Maybe from CSV, HSV, Herrod. But there's no way Ford or Holden will be pushing that sort of power in the next model lineip.

As JEM says 350kW certainly wont be in the standard model lineup.

That said the Cobra R was their 1st serious NA 5.4 effort so there'll be some room for development. Just look at the trick magnesium inlet with dual MAFs that the FR500 runs. That baby was advertised as having 300kW on paper.

5.4 just about right

I was reading in a American sports car mag that the Ford Corbra R SVT version from their 4.6L was producing 385hp, know that is out of an engine that has been pretty well worked over and still comes under the 300kW mark. They will need to be doing something speacial with the 5.4 to get that. But I reckon as long as you can get 200kW at the rear wheels will keep me happy.

Marcus, the 385Hp rating is hugely underrated.
Motor Trend dynoed a Cobra R and got 376.1Hp and 385.9Tq at the WHEELS :eek::eek: There dynos have about 12.5-15% drivetrain loss for manuals, so its really got around 430Hp or so.

Welcome to the village Marcus.. ;) :D :thumbup:

Anyone know what 200 at the wheels is at the fly from the alloy 5.4?? Going on the 30% drivetrain loss that gives us 260 at the fly. I reckon that figure is a bit off myself.
We'll need around 270-290 at the fly for the T's and around 310-320 for a GT or HO

Well if they can produce about 330kw NA at the fly that will prove that engine is worth while.
I know ford and holden won't make over 300kw, but if herod or someother tuning company can get 330Kw+ then ford will be a real match for holden. CSV has got the Veloce at 330kw.

Actually if your getting 200Kw at the wheels youve got 285Kw at the engine with 30% drivetrain loss

285Kw - 30% = 200Kw
200Kw / 0.7 = 285kw

200Kw + 30% = 260Kw (incorrect)

Right then boys, what do you think I need to do to a dual Fuel 6 cylinder to get it up to the 285kW at the flywheel.
It was funny because, I don't know if you boys ever saw the Predetor but you seem to be pretty close to what is going on. Right back to my point, it was a pure gas V8 producing the good old 200kW, we use to think that was a fair bit 3 years ago.
Do you ever think we are going to see another power limit on Australian vehicles like waas implimented at the Phase IV stage?

And thanks boys I am glad to be here, loving it already.

Don't sell the Predator short Marcus. IIRC it was actually an XR6 motor woth Powerdyne blower attached running at 6lb boost and made 230kW. Shame the mags never got times on it, they broke the blower belt while they had it.

I'll take one for my escort. It won't screw the weight dist. up enough to make the back end stick up, will it? Oh yeah, I'll need a 3 foot long gas pedal too... :)
