Wheels re-test GTS & GT-F on the dyno

Sioso · 08-08-2014, 05:01 PM

Just got the latest Wheels Magazine:
Re-test results

Herrod Dyno -
GT-F - 323.7rwkw
GTS - 306.7rwkw

Dyno Dynamics -
GT-F - 343.4rwkw
GTS - 322.1rwkw

Also have a rear end shot of the new XR8 (CGI) - I will post later when I get the chance.

So the "worlds fastest ute" will be underpowered...

lel.

Build ford tuff, great result

Trump · 08-08-2014, 05:22 PM

Interesting. Can't wait for the Holden fanbois to react

where's Mr Streetmachine (blownvn) or whatever he wants to call himself. the mainline dyno figure for the GT-F isn't that much different from the original wheels test, but the GTS seems to have lost a fair chunk of performance. so who was doing the fiddling again??

interestingly, the GTS result is more in line with the trend set already by private owners. most in the know already knew the GTS was only around 320rwkw on average.

Just as i called it with him he was full of **** mr credibility with his face shoving maybe he needs to stop shoving his **** uphill.

A resounding win for the ford most powerful car ever period full stop no returns

Benny · 08-08-2014, 06:41 PM

Clearly they forgot to engage the over boost on the GTS.

The GTS doesn't have overboost, being intercooled it doesn't need to keep temps in check like the GTF does.

That is the key to this new result, the GTS is consistent by being intercooled, but the GTF needs to have just the right intake temps to get it making max overboost.

Yes I'm aware of that, I was referring to the comment Dowling made when he heard the GT-F has over boost.

Blem · 08-08-2014, 06:43 PM

So those figures don't account for overboost ?
Working on 320rwkw what does that equate to at flywheel ?
Cars were manual ?

so long as the intake temps were under control, that would indeed include 'overboost'.

Both cars were auto's

Both cars confirmed completely factory and had a qualified independent engineer in attendance.
Ambient air temps, tyre pressure and strapping all equal.

Isn't the GTS is still quicker over the quarter mile.

How does the GT-F dyno against the r-spec

dyno queen

same/similar.

so far, that has been the case, although a recent test only had them separated by a tenth of a second.

the GTS would be easier to get a good time out of it consistently. as an overall package, it is a better car.

ford man xf · 08-08-2014, 07:24 PM

The GTS is still more powerful, because power figures are read at the flywheel, not the treads, as has already been stated the GTS has more beefier compononents that sap more power than the GT-F.
Unless someone takes the GT-F Coyote motor out and dyno's it at the flywheel we will never know what it actually makes, we can estimate it though.

Sioso · 08-08-2014, 07:33 PM

The GT-F took a few runs too get up to optimal temp.
From the magazine:
"For the transient overboost to be effective, it runs off manifold temperature, so we need consistent temps of about 50 - 60 degrees", GT-F project manager Justin Capicchiano said.
"The GT-F is always between 351 and that additional 15%, but how much depends on the conditions. So you're always in transient overboost, but you'll never go below that 351kw figure, which is why we put 351 on the side of the car".

stazza · 08-08-2014, 07:36 PM

Bahaha that must've been hard for Wheels to swallow. Awesome!

Wonder if Dowling will amend his previous articles stating the GTS as being more powerful.

Sioso · 08-08-2014, 07:40 PM

They also did a comparison between the GTS and GT-F but for some reason tested an auto GT-F against a manual GTS

Figures below:
GTS Manual
0-100 4.5
1/4 mile 12.6 @ 190.6 km/h
80-120km/h 2.4

GT-F Auto
0-100 4.7
1/4 mile 12.7 @186.7 km/h
80-120km/h 2.4

If EVO Magazine was conducting this test, it would have some credibility. But since it was conducted by Wheels

the GTS is about 300 lbs heavier than the GT..F

105lbs. Of course in kg that sounds less impressive again.

It'd be appreciated if the dyno queen style comments are left out of the thread. Unnecessary and argumentative.

Fact. The GTS is the better overall vehicle that's life. And at 6.2l it ought to out-torque the Miami. And does as the charts show. But for a hi tech baby 5.0 the Miami hammers, it's just unfortunate FPV never had a newer chassis to take it to HSV as no doubt they'd have loved to. And that is how history will record the final GT.

Published curb weights put the numbers close to 2000 kg for the GTS and around 1850 kg for the GTF. Would be good to see both put on a weigh bridge with a full tank though to know for sure.

1881 manual 1892 auto...multiple sources, 1835-1845 can't seem to make up its mind for GT (is GTF lighter?)

Happy to be corrected is it calculated differently for the two?

Autocar N.Z. put's tested cars on the weighbridge and with a full tank of fuel the results were
GTS 1902 kg's
GT-P 1855 kg's

They haven't tested a GT-F yet but I'd assume it'll be a similar weight to a GT-P running the same 6/4 Brembo's. I'm waiting for a decent track comparison which will be interesting.

Sioso · 09-08-2014, 04:40 PM

In the latest Wheels they have weights as:
GT-F auto - 1850kg
GTS manual - 1881kg

Windsor220 · 08-08-2014, 07:47 PM

So they are basically the same for power and acceleration just the GTS has it in the handling department.

**Polyal** · 08-08-2014, 08:20 PM

Seriously it cant be hard to source two manuals....and to think they get paid good money to come up with this crap.

Its all a ****ing contest, Ford can still claim being more "powerful" but it seems the GTS will be quicker I believe because lets be honest they spent more on width and tyre quality.

The real test is similar tyre dimensions and compounds, both manual if doing dyno runs and both auto when chasing an ET.

The price difference between them leaves GTF owners with enough coin for width and rubber. Ford ran out of money, but still sold all 500. Has HSV sold that many 80k commodores in the same period? Ever?
