how do two dynos give a 25rwkw difference in power, like i know dynos differ but 25rwkw?!?!?!?!,
im not surprised the new boss produces more power then stated, new engine thats supercharged and it only produces 20 more kws then the previous 5.4L, that would just be silly

no it's not, use your brain.
you spend big bucks developing a new motor, why would you release it making its maximum possible power? it leaves no scope for further power upgrades in following models.
not to mention there will already be some sour grapes from FG GT buyers, can you imagine if they made it even more powerful?
it'd be a f**k you to everyone who bought an FG GT.

Holden have done that with every model from VS commodore onwards and the dingbat bogans still front up to the dealer every year and a half wanting to trade up to the latest model.

i see some people are saying that the car given to these magazine guys was alterd in some way to make it more powerful..
as for another comment one person says that the motor in the GS is completely different to the one in the GT? i thought it was just a few slight differences plus a different tune or somthin?

would ford purposely let some magazine crew that want to test a stock standard car get thier hand on a car that has been modified?... if so it would be a huge mistake.

regardless of tune, ambient conditions, etc, i think the true point here it the coyote is an animal out of the box, with plenty of scope for improvement.

Of course FPV would understate it's performance.

By the time HSV get onto that, the second gen model will be well into development.

i think what FPV is looking for is a way to make HSV push it's 6.2 further than it should go, causing reliability problems etc, thus causing customer dissatisfaction and a push for a new motor to compete.

at the end of the day this is business, and anyway FPV can test/push HSV past their limits whilst staying inside theirs, the better business will be.

purely and simply i feel that's where it's at now

1. KPM would have no reason to keep the before figure low like the 'claimed' numbers so their tunes look better, would they? :roll:

2. The engines are supposed to loosen up with use, and this one can't have had much use this soon (note the date of the KPM post is 3/11)

3. Auto vs manual (another 10rwkW)

4. It's a GS, not a GT :wink: Which means even the 'poverty-pack' FPV is more powerful than the top-of-the-line HSV currently on sale

GT and GS motors are the same motor loaded with a different tune. There is meant to be 20kw at the fly between them.
266rwkw seems like a much more believable number from 315fwkw, which indicates that the original GT tested probably was tampered with to produce the big numbers it pulled.

It is more powerful than the current HSVs though, VE GTS's are pulling anywhere between 220-260rwkw stock, pending dyno and trans etc.

It'll be interesting to see what production run GTs and GSs pull on the dyno and at the strip, hopefully shouldnt be too long before numbers start popping up.

by your logic it's just as likely that KPM are talking s**t to make their work look more impressive.
or that the GT is under quoted and the GS is over quoted.
or that the KPM car is f**k.
or that the Street Fords GT was f**k.
who knows, who cares.

i look at it this way.
if the GT street fords tested made that power with an FPV 'press car tickle' tune, imagine what they are going to do tune only once they hit the dynos of places like Bluepower and XFT.

RIP F6, you had a hell of a run.

Seems like a no brainer to me. The Coyote makes 412hp normally aspirated so there is no way it could only make 335kw(449hp) with a blower on it!? Unless it was NO pounds boost!
A 50% increase on 412hp for a blower and you have 618hp!
Beats me why they used harrop when Roush has already made everything required!?...no piddly 1.9L blower either! Probably something to do with Ford not wanting anything to do with what FPV wanted?
Ford has done lots of understating HP figures over the years(428CJ is a classic example) so it's not such a surprise. It's just surprising how little they could think we'd believe it was!

IIRC NA coyote has 11:1 comp. Our blown motor has only 9.2:1 or something along those lines.
Harrop was selected instead of Roush due to some s**t form of local content rules. it doesn't make sense because the GM motors are installed as is from the states, only addition being Holden specific engine covers..

As for the death of the F6, not yet. Not by any stretch of my imagination. There are a few F6's making in excess of the magical 746rwkW at the moment. Once the tuned coyotes surpass this figure then you can make plans for an F6 memorial service. Be interesting to see what the dollar per kW figure would be when nodding these two engines. Looks like the V8 will come out cheaper to mod.

the local content thing is probably an internal FPV/Ford Aus goal?
at their little launch night the FPV/Prodrive engineers mentioned using the newish Eaton TVS lobes in the blower too, is the Roush a twinscrew or an older style Eaton?

mod motors have been doing over 1000rwhp for years. and backing that dyno figure up with the times to match too :lol:
F6 is well behind the 8 ball in that regard.
