FPV's 351kw GT-F more powerful than HSV's 430kw GTS, How did this happen?

If I wanted a car with good fuel economy I would have bought a Clubsport......................................

It's funny, but i was quite critical of the FG 'taxi spec' interior, and a big fan of the VF. Having spent time in the cabin though, i can quite honestly say it's a comfortable place to be, and when the right foot is pushed to the floor, not even a Mercedes interior would matter to me. Driving from Canberra to Melbourne, and several other longs trips, i can honestly say that i've never caught myself wishing for a nicer interior, or more tech. One push of the loud pedal and realise why i opted for it.

I don't get time to worry about the tech inside the car when i am actually out enjoying the car for how it was meant to be driven. The only tech i actually miss is auto dip passenger mirror when reversing.

Completely understand where others are coming from though, and the interior and lack of modern features would be a real clincher in swaying away from the miami. Perhaps the XR8 will fill that void, and people can have the updated interior, more tech and that awesome motor.

edit: and yep, more and more buyers consider fuel economy in their purchase criteria. But those who want outright performance know that the two don't really go hand in hand (unless you're buying a very expensive euro, and never belt it). I average about 13-14L/100km most times, and the best my caprice ever did in similar circumstances was about 12-12.5L/100km...

End of the day, as long as you are happy with what you got for the money, that is all that matters.

My next door neighbour used to have a G6E Turbo. Loved it.
Then he traded it in on a VF SSV Redline wagon.
And he loves that. Even more so, because it's more practical than the sedan he had, and with an exhaust change it sounds meaty compared to the whooshy turbo.
He misses the "rush" of the turbo, but he doesn't miss the laggy low rev performance.
Same buyer, but different priorities at different times.
It's good to have choice.

If people are happy to have the supercharged Miami and coilovers, and will put up with the taxi spec interior and poor "tall boy" seating position, well, that again is up to them to decide what are their most important priorities in a new car are...

That’s my priorities right there. I’d have one of those Ford thingies like that for a weekender when I drive for fun and use a VF SS Redline for going to the shops. Creature comforts are good for a daily.

The straight line performance of that Ford is fantastic value for the money and I’m not racing around the track so I won’t miss the so called superior chassis of the Holden.

I’m not overly interested in the GTS or GT F but a supercharged XR8 if it eventuates will end up in my garage for use on the weekend.

Have posted dyno sheets from Bullet Performance Racing a Ford tuner to balance the ledger, stock GT 284rwkw and stock GS 262rwkw.

I also remember reading a post on AFF a couple of years ago and Rob Herrod himself even said that the GS makes about 270rwkw and the GT 280rwkw.

Hi adr8, I take it that Rod Herrod is using a well dialled in dyno?

[FFAMan]

Rob himself told me a few days ago the average number he's seen for 335's is about 320rwkw... This is based on hundreds of runs since the 335 hit the market.

I tried to do a search under Herrod's username on AFF for the thread I am talking about but the search history only goes back to 2013, I will keep searching and if I can find it I will post it.
I do remember it was a thread about dyno results and one member got 270 rwkw from his GS and was complaining as to why it was so low compared to others in the thread and Rob Herrod said that's how much they make std and the GT's about 280 rwkw.

Edit: I found the thread, I am not allowed to post a link to another forum so I will mention the title "Power output of Miami Engines" these are the posts

270rwkw.

Now either I have a dud motor or there are some extremely happy dyno's out there

no you dont max , that is what they make. the others must be tuned as the figures that they are quoting are what i get tuned.


Obviously no mention of GT dyno figures in that post so I got that wrong, but I did read it when it was posted in 2012 so memory of it was a bit hazy lol

[Toa]

that's cool adr8, I have heard the same from him back in 2012 when my brothers gt got some mods from them

I just don't trust many dyno numbers, especially shootout mode, I believe most to be a marketing tool

I found the dyno sheet of my brothers black edition GT, this was a little unusual though



The guys at herrod put the gt on the rollers and she pulled 338kw at the wheels on the first run, then backed it up with a second and a third. They then concluded that the dyno was out of whack, so they supposedly spent 2 hours recalibrating the unit before putting the GT black back on the rollers only to find it pulled 338rwkw again...
This left them scratching their heads.
They then realised they had another standard 335 GT in the shop, so they put it on the rollers and found it put out the normalish 277rwkw...

At this point they called up my brother and asked him what sort of modifications he had done to the car? he replied honestly "none, you are the first guys to play with her"
This left them scratching their heads some more, before asking him how he has been driving it? again he honestly replied "like I stole it..."
This made the herrod guys audibly chuckle over the phone.

The above results are quite self explanatory, and very impressive for a drop off in the morning, pick up in the afternoon, standard intake, standard exhaust, no internals scenario, and an absolute animal to drive

And an intercooler!

[Vulture]

10.85 off the showroom floor. 1 Hellcat please sir.

To be annoyingly accurate, it does 11.2 of the showroom floor, 10.8 with drag radials.

Surprised no one has posted yet. Wheels did the test again with engineers from both camps, an independent and at two different dynos. GT-F can now be officially called the most powerful Aussie production car ever made.

While this is all well and good. The GTS is still the better car for the money IMO compared to the GT-F. But with the pending XR8 soon to be released with the same drivetrain; all be it in detuned form. I reckon its going to be one hell of a good value car being it should be ~$40k less than a GTS but with more power.

[offshore]

Transient over boost what a pathetic excuse for the lack of intercooler. In Australian heat it means it will hardly every get into over boost. Next bring on the Mustang instead of this underwhelming Ford.

Yet even without the cooler and a 1.2L deficit it makes more power than the GTS. If a car can do 6 pulls on a dyno and remain below 60ºC in the manifold, its doing bloody well. Its common to see supercharged LS engines that "are" intercooled get hotter than that and won't get 6 pulls in before they start loosing power, let alone make more like the GT-F does.
