Final FPV sparks kilowatt controversy (GT-F vs GTS)

[hootar]

Your so called press cars are going to be auctioned off after the press are finished with them. In this day and age a fair percentage of owners dyno test their cars. It's not a big hassle to do that now. If ford have upped the press cars power and then other people dyno test and find that they are all 30+ kW short of the 001 and 014 numbers then ford would have a lot explaining to do. I'm going to assume that your next response would be to say well ford could detune the engine before selling them. If that happened and the new owners of 001 and 014 did a dyno test and they had lost heaps of power then ford would be in the **** again.

If we look at history Ford tend to under quote power figures. People like to hear big numbers, bigger is better. Hsv say 430 kW and dyno says 330. Ford say 351 kW dyno says some where between 311 and 348. Now tell me who do you think is playing with figures to impress mr ave joe blow?

Spend some time on YouTube or googling and you will find that what the 335 Miami is making is very consistent quality power. There will always be a couple of roughies in there but the vast majority are on the money. What Ford are saying is that the 351 Miami will on average make a small percentage more power. (16 kW approx). Ford have every right to defend that claim against wheels and vcm. I guess you would too if someone called you a liar!

[PepeLePew]

Both threads tend to end in the 'who cares its just a number' war. Only reason I'm checking into both is its about time there was less tolerance for the publication of crap. THATS INTERESTING beyond arguments about numbers. Should it prove out that this 'independent' shop are correct, the majority of tuners around the country will need some attention as apparently their claims are wrong and Autotechnique is the source of truth

Though hey if all those unscrupulous tuners when tuning fudge, don't they LOWER the start figure to exaggerate their results not pump it up? A lot of pre/post tune numbers out there that agree with the expected average of the 335....

Lets forget the us vs them numbers. Lets see whats happened if this proves out the initial figures were wrong. And we can all run around the block naked if they're correct.

Exactly... it's not about which car makes more power at the wheels but these "dyno battles" are just proof that a much smaller high-tech V8 can match and sometimes beat a larger pushrod layout.

We should all remember that even though both motors have the same size blower, the LSA is also intercooled yet still stuggles to make over 330rwkw while the non-intercooled Coyote 5.0 is averaging this figure ! (311-348rwkw)

[burnz]

if both cars are cherished, then they wont see much over 3,000 RPM.
unless burnouts, donuts, circle work, linelockers...are the order of the day..

dyno's are one thing, but weight shifted is another.. 4250lbs vs 4400lbs...terminal speed, that's the pudding.. in outright BHP.

track weapons, well that's car setup.

[HULK_I6T]

Im not sure why the appeal?

Ford say under certain conditions the transient overboost will give upto 15% more power..

Maybe the 311rwkw is without overboost and the 348rwkw is with overboost. If ford dont want to guarantee the overboost function then why get upset with the varied output?

Believe me mine will see the redline when it's driven. Can't wait to drive it in anger with the manual as I always missed having full control with the ZF. It's a good trans but when you right into it you can't beat that total control a gearbox offers.

I am not saying they are or have but I certainly wouldn't bet against it.
Powerful and fast car, may be some good PR? Sell a few more? After all they're a business, there to make money and wouldn't the first to do such a thing.

I mean really what harm does it do? It impresses the feeble minded who look into figures from dynos that have questionable accuracy, that make mountains out of molehills and scream to the hilltops of blatant bias of any organisation or individual that report outputs outside of guesstimated figures by some keyboard warrior who could barely even read the figures.

In the end the people that buy the car wouldn't even know if their car was 10 - 30 kw down or up. A majority of customers buy the car to drive each day to and from work with an average speed of 60 - 65 km/h, acceleration figures far higher than what the vehicle can really do.

Funny how so many here don't care that the Falcon has been slower in the past, less advanced, etc, that their choice of purchase was they liked the car in the first place. So really all this bickering is for nothing, the people that would lay down their hard earned would have done it if the car produced 300kw, 350 or even 400kw.

Mate, it's a Ford forum. We own these cars. There are probably over 100 GT335 owners on here. Dozens and dozens of us have had our cars dyno'd. Not to measure the power, not to brag, not because it's the be all and end all. But as a basis to modify.

We therefore know roughly what they make. Central limit theorem states that with around 30 observations statistical error falls away very sharply if you derive and average.

On this basis I KNOW a GT335 makes around 320 or 330rwkw
(Mine was a little lower than average @ 320)

I know it. Other owners and enthusiasts who take a proper interest know it. And Ford know it.

So all this rubbish is just that. Wheels tried to post jarvis results and got caught out

So what are you trying get at here?
You dyno your car? Well congrats for you and I hope it serves its purpose for you.

You pretty much supported my post, there are variations in the results, yours got ~10kw less than some, others may have got a lot less others may have got more. My post was about and I thought it was quite clearly written that who cares what dyno results the car gets. Most people wouldn't even notice a drop or an increase in power when they drive the car on a normal day.

There are far too many variables within a dyno readout. They just feed trolls who like argue who's got the bigger wang when in actual fact the results can vary between cars and dynos (you just pointed that out yourself).

Ok then....let's just get rid of all dynos......there goes the whole modding and aftermarket community. Don't be sooo stupid. People(99%of them) don't drive them to the max.....so all they know is what power it has.
Hence why it's such a BIG deal about which car has the most power.
Everyone wants to know which car is the most powerfull car in aus!!!......except maybe you

[1TUFFUTE]

And what Shonky pointed out clear as day....was that it's the fact that Multiple GT335 cars over many years have given us an average dyno reading to expect. His car included. Pretty basic.
Those in the know are also aware the 351 tune is not just a badge either.....it's actually more power. It's been hinted at by some excited RSPEC owners here that ford may be offering the new 351 tune for them so their RSPEC isn't diminished by the fact the GTF borrows all it's benifits/upgrades from the acclaimed GT Rspec! Something like that

Clearly didn't read my post(s).
Not even going to respond

[1TUFFUTE]

Your whole post is attacking the idea that dynos have any purpose. You think that dynos are only for the **** factor. And that simply because different cars can dyno different readings that somehow makes dynos irrelevant or once again simple **** factor!
Did you not realize the same GTF was used for both dynos.....the first time it achieved LESS then even the less powerfull GT335s average. The second time it achieved exactly what ford said it would, and what they had achieved themselves. Both GTS were different but made similiar power.
The first was in suspect circumstances and it was also a well known Holden tuner.
It's such a BIG story.....yet soooo simple to understand.
I don't get why some keep claiming no one cares whose the most powerfull car in aus!!!
I don't get why some think 311rwkws is normal for a modern GTF(who everyone knows actually achieve closer too the badge in ACTUALL rw power)
Anyway........

It's a proud day for Ford in general, and GT-F owners in particular!

[tweeked]

I went to a Dyno Day at Autotechnique a few years back. On my regular tune in Dyno Day conditions my car has mad between 327 and 335 rwkw (5 different Dyno Dynamics dynos)

At Autotechnique it made 307 on their Mainline Dyno.

Yes they tune both Holdens and Fords, but they are the "Herrods" of HP Tuners for the GM product. They are firmly on the Red side.

One of the best looking workshops I have ever seen by the way............

[HULK_I6T]

The GT-F seems to be one heck of a great ride. (As is the regular GT335)

Pity they cant tune a 5.4 tho

The sad thing is the full spec Miami was never released. Would have belted the HSV for six (and then some).

The 450kw intercooled version Pro Drive developed.

[40RDT]

With the way FPV rates their motors that would have been around 450rwkw, I dont think the rest of the car would have liked it though haha, would have been a good send off for FPV's last model

Would have been interesting to see what HSV would have done to counter that

[graphicgoose]

Yeah apparently the firewall, which they'd already beefed up for the Miami, started to part ways with the floor hahaha. The deemed it to be unwarrantable at which point.

Some people want their cars to last longer than a few months. I'll take that over bragging rights when spending that sort of coin.

Well this is what someone with a bit more insight (works for Ford) had to say about it in another thread:

Testing showed the stress was too great along the area where the firewall meets the floor, an area that was already beefed up for the 335. It required further strengthening, which then required it to be re-crash tested, and that's where it all went tit's up, as Prodrive were expecting Ford to do it, whereas Ford were expecting Prodrive to do it. Many arguments ensued. Ended up in the too hard basket. The crash testing is not cheap, somewhere in the millions of dollars.

Problems may never show on tuned Miami's but who knows, after 200,000 km's of hard work they may be a bit looser in the body than a standard one, but that is to expected of any car making big torque.

The floors won't suddenly fall out of them like Fast and Furious cause they are running too much noooossss

But Ford probably have global durability standards for things like torsional rigidity etc. It may only be a minor change but it's enough for it to fail that test and require modification.

I don't think it's a concern for highly modified Coyote owners.

The power output must be stated for the power it can achieve at any time - 351 engine KW (though it is more, anyway). It can still reach 404KW under most conditions, just for shorter bursts (I read on another thread).

I have not bought a wheels mag for years.
They are all holden and just like holden they talk BS.

Don't forget it was one of their journalists (Jesse Taylor) who got the best 4.5 to 100 and 12.6 sec 400 metre time out of an RSPEC.

[blownvn]

I guess it's time for me to weigh in. I've read most of the comments and had a good laugh at some, especially at the conspiracy theory people who think that this is some kind of attack on Ford Australia.

Here's how all this came about. As most know I work for Street Machine and I've been a member here for years. I play with Fords, Holden and Chryslers, if it was said that I favoured any brand it would be Chrysler but I'll play with anything.

At Street Machine we share office space with Wheels, Motor and Unique cars, and I sit on the other side of the cubicle wall from the Wheels guys and the subject of the dynoing the GTS and GT-F came up. The Wheels guys asked me to recommend a workshop and I said VCM Performance.

Why? Because's it's a roomy and tidy workshop with an easy to access dyno and they're friendly guys. I've filmed there before and it looks good on video. No other reason.

Wheels were only going to get dyno figures for print but I suggested we film the whole thing and my boss Simon suggested I film it and we share the footage for a simultaneous release across Wheels and Street Machine because we have two different audiences.

So the guys rang Mario at VCM on my advice and he was happy to do the test there. We drove the cars there and because the Ford has no intercooler we decided to put it on the rollers second to give it some cool down time.

There was no fanfare, no conspiracy, just roll the cars on, test, and roll them off and film the results. Here's the Street Machine video in case you haven't seen it.

https://www.youtube.com/watch?v=tME5so6VbqU

As you see the GTS made 330rwkw on it's first run and it made 327rwkw on it's second run. Now I've filmed ALOT of dyno runs in the past and I saw nothing funky at all, and generally, in my experience, we'll see that the HP at the rear wheels will roughly equal the KW at the flywheel +/-5%. So when the GTS made 442.5rwhp on a claimed 430kw I didn't think that was unusual.

Then we ran the GT-F on the rollers. No one expected the GT-F to beat the GTS but we felt that if it got within 20kw that would be a respectable result given the claimed 351kw. Now we all know about the "transient overboost" (stupid name) which provides up to 404kw. I was at the GT-F launch at You Yangs and I asked the engineers flat out if the car made any more boost under that condition and they admitted that it didn't. It's all in the timing based on intake heat - basically if the intake temps are too high you don't get the full output. It's as simple as that.

Anyway we thought that if it made over 310rwkw or 415rwhp that would be a respectable result. First run was 308.8rwkw and the second run went 304.5rwkw and we knew it was only going to get worse if we kept going, so we let the GT-F cool down in the dyno room for 10mins or so with the dyno fan on full blast. In the true spirit on the dyno test we probably shouldn't have but we wanted to see if the FPV could get over 310rwkw.

After the cool down we ran the car up again at it made the 311.3rwkw figure that everyone seems to have a problem with. So we went with the best figures of both. Maybe we should have averaged the figures, but that wouldn't help the FPV either. But we felt the Ford had performed quite well in the circumstances and having a separation of just 19kw or 25hp at the wheels showed the cars were going to be close in performance.

At this point we decided to wait until Monday the 7th to release the results, which was our first mistake. We should have just gone straight back to the office, edited the footage to suit our respective audiences and let fly.

Then someone gave Ford a heads up on the results and the phone lines between Ford and the Bauer media office basically caught fire. Ford were not happy and to be honest I don't really understand their problem. Yes they didn't make as much as the HSV GTS, but it was a lot closer than anyone who knew dynos thought it would be.

Look at the facts:

1) Both cars were auto
2) Both cars were driven straight to VCM and run as is
3) You can't compare different brand dynos. Every business has their dyno set up differently and there's variation across brands. The only way to make a fair comparison is same day, same dyno
5) Ford has underclaimed the supercharged Miami V8 from Day 1 and this just confuses people
6) The FPV has quad cams, but is only 5-litres and has no intercooler
7) The HSV might be a pushrod V8, but it has 6.2-litres and an intercooler

If Ford/FPV wanted the GT-F to be the big dog of Australian performance they should have put an intercooler in the bloody thing. We all know what a difference that makes to them.

At the launch I asked why with the GT-F being the last GT Falcon and everything that went with that was it only 351kw? They said that 351 was an iconic number and they wanted to honour that, which is fine, but I said 427 is an iconic number for Ford guys as well and it would have put it more in line with the HSV GTS. There was a lot of heming and hawing and foot shuffling because they knew their car didn't have the power of the HSV GTS.

But now they're claiming it makes as much as 351rwkw? Give me a break.

So anyway, as we prepared to release our videos Ford threatened and pleaded with Wheels for the results to not be published (we didn't field any calls form Ford at Street Machine, maybe because Simon was in QLD). This went right to the top of the food chain at Ford. I can't say too much about all that, but there were at least a dozen calls back and forth by my reckoning.

Ford claimed there must have been something wrong with GT-F-014 to make such a "low figure" and they claimed they tested it themselves and claimed they made somewhere close to 351rwkw. We at Street Machine were happy they we had given both cars a fair go and wanted to go ahead with the video Monday night, but Wheels wanted to hold back because there was more talks planned with Ford. So we decided to sit on it.

Talks between Wheels and Ford continued on Tuesday morning and then about midday Motoring.com.au went to print with "their results" (suspiciously convenient) which we've all seen. So we hit the go button with both our videos. Wheels went first, and we were a couple hours later with ours because no-one was in the SM office to click go.

Naturally the results differ because different dyno and different cars, but both results used the same GT-F-014 and somehow they managed 348rwkw where we managed 311rwkw, which is a huge difference in anyone's language.

Why the difference? Well look at the torque figures that Motoring.com.au are claiming. They claim 721Nm for the GT-F when we all know that Ford have torque limited the GT-F (and all the previous Miami powered cars) to 570Nm. Did Ford turn the torque protection off in the software before handing the car to Motoring.com.au for their "independent test"? Who knows?

It makes you wonder.

At the end of the day I have no dog in this fight, we only test Fords and Holdens occasionally at SM, but what started a simple, "Hey, what do you reckon they make on the dyno?" turned into a massive **** fight.

At the end of the day you have to ask yourself, without bringing brand loyalty into it, will an unintercooled 5-litre make as much power as an intercooled 6.2-litre? If Ford wanted to win this battle they just had to build the right car (ie: intercooled with 400kw+), we all wanted to see it.

[ReVd_uP]

Having had a lot of GT335's on the rollers, there is a fair amount of variance in RWKW figures (as there is with any mass produced car) ,the lowest we had was around 280 the highest a tad over 330, all the same dyno, strapped in the same way, by the same person.
So I don't see why there is such disbelief in 311 vs 348 in two different cars on two different dynos.....

Especially different brand dynos as in this case. Although 37kW is a fair difference on what is supposed to be the same car, I can understand people getting their panties in a twist.
