Go Auto - Ford blows XR8

[jpd80]

without wider and stickier rear tyres, all of this supercharged V8 power is wasted.
Ford really need to fix this, it's responsible for those bad launches and ordinary times against Holden V8s.

And while they're at it fix those darned diff bushes and skinny axles that are prone to stick slip.
They're not a problem now but when you get a good blown engine hanging of them, look out

Pretty sure the tyre issue is being sorted. Have read about 9" or 9.5" wheels on this forum several times.

Whole driveline and all bushes will need a serious overhaul if the numbers I've heard are true.

While i understand what you're trying to say the fact remains the G6ET can get high 12's, yes albeit with all the stars aligned, right air temp on a sticky track etc with a single spinner diff through the factory 245's...
So "traction issues" are a complex mix of circumstances..

There's more to it than just tyre width, the suspension geometry will also dictate how it puts its power down..
Better compounds, better ratios and better rear suspension geometry will help.. not just 1 element in isolation...

If you couldn't change anything else, the wider tyres would certainly help a bunch.
They did for Holden..

They'd make bugger all difference if they used the same compound as they currently do....
The person controlling the right pedal will dictate how much traction they do or don't have...

[Franco Cozzo]

They could just add it as an option, or make a set of really good street tyres standard on the XR and FPV series?

Once again , like 4Vman has said people place to much emphasis on number's "badged".
Even if the Patrol has 300kw, ask yourself, do you see a Nissan Patrol outdoing or blowing away a XR8 powered coyote ???.

Oh.. and the new Nissan patrol is 180kw....

Yeah, (a mate's Camaro 450rwkw) they're a lot of fun!!!

Probably not a lot of fun for FoMoCo to engineer to a sufficiently high standard without them spending time in the Ford Service Centres undergoing warranty repairs though

[ford man xf]

The power figures just don't add up...

[Iggypoppin']

a few questions have been popping up in my head of late, and one of those was this: with a fairly exponential curve upwards of power from early 90's to now(read: V8's starting around the 160kw mark and progressively gaining more as the years go on, 200 by mid AU, then T series 220 and 250, XR8 260 and XR6T 245, F6 270 GT 290, then swap those high numbers for even higher ones, 310 and 315, 302 for the specials, and 290 and 270 become the norm for lower spec) how long is it before they just can't make anymore power? i dont think theyre going to "run out of puff" so to speak. you can make monstrous power if you want. but Gov wont let them and at some stage, economically, it will not be viable. the constant upgrading of transmissions and drivelines, researching new and improved bushes and the like, will mean that these peak power and torque figures should plateau at some point...shouldn't they? far be it from me to hope that they do in the near future...i'd love to see a production car built in Aus with 500kw in 10 years time...but surely its going to be stopped at some point?

point two, and that is, while reading an old street machines magazine, it had a bit on 9inch alloy diffs for VT and VX commodores. swap em over, retain the IRS etc and you have a bullet proof diff assembly. should ford research a 9inch alloy diff to slot into the control blade IRS to make it a nice strong diff for the power upgrades planned from factory for coyote? and beyond?(probably a bit late for FGII release.) the units i was reading IIRC where around 5500 bucks. now, if that was a cost spread throughout the cost of the whole car, then obviously bulk buying power or whatever, would reduce the cost further...well, is this a good idea??

It is reaching a point where enough is enough.. ANY regular production car under 100k that can accelerate 0-100 in under 5 seconds and has 325ish kw is bordering on enough.

I see the future of performance vehicles in reducing weight, fuel consumption and improving handling over wholesale power increases.

Hell even my N/A FG XR6 is as fast as my AU220XR8 was..... For a base model engine its extremely lively and feels as fast as the best from Ford/Holden only 10 years ago...
The power upgrades can't keep on climbing at its current rate because human reaction skills and driving abilities havent kept up with technology....

Plus the fact the boss powered cars are quite nose-heavy; not the best for 60 footers. Alloy v8 should mend that problem a little.

Are you kidding me? You cannot win with some people - they do nothing, add a few KWs they get criticised for not doing enough, now they put a fantastic engine in it like this one and you think they've done too much?!

Yes... I think he's more concerned about the restoration of the pecking order than looking at the bigger picture and the benefits it brings to Ford or the brand....

I'm not saying I want a factory 450kw car. What I'm saying is that if you scale the power of the current patrol and fpv gt by the same percentage you would end up with a 300kw patrol and a 450kw gt.

Also Im well aware that the 315kw power output is for the xr8. Which is the model I'm planing on purchasing.

I have experianced 450kw also it was a blown maloo. Although that was fwkw.

[xr8ted]

I personally dont see what all the fuss is about the FWKW rating. I would have been happy to see a 300kw XR8 with improved low/mid range torque. To me 315kw for an XR8 sounds very exciting, and I am not fussed at all that is only a few kw up on the mustang. If it has a meaty low to mid range, with a nice top end to matched (which supercharged 8s normally seem pretty good at doing), then I will be wrapped.

HUH??

If you scale the power of a GT to the same as a new 300kw Patrol (KW/Tonne) you'd end up with 196KW GT......

I think it's safe to say that Ford/FPV wouldn't waste significant investment, development and time on an engine program for only a handful of kilowatts and no performance/economy advantage over the out-going model.

I think we should wait and see how things pan out before judging what this 315kw number really means.

exactly!
We are getting a supercharged 5.0 v8 that is almost certainly underrated by at least 30-40kw. We KNOW it will be much faster, lighter and more economical. It will be backed up by one of the worlds finest 6speed automatics and we're complaining about the specified power output number in the brochure????? :

Cant wait to see what the aftermarket is going to do with this engine OHHHH BABY!

[Transfiguring R]

Well said there, Ghiadude. 25 more badge kws than the current XR8, lighter, better power delivery due to forced induction (more torque at low rpms), better fuel economy. This is a huge win for Ford. The XR6T is a great car, now the XR8 will match it at the least. People shouldn't be complaining (no one complains about the XR6T...), they should be rejoicing.

Put it this way. This new XR8, by the sounds of it, will compare to HSVs in terms of performance. This is very exciting news, especially if this upgrade is an indication of what FPV have in store.

The only things I would be worried about is rubber and brakes, which are already a problem for the XR6T and the current XR8.

Standard brakes...

Front : 355x32
Rear: 328x26

BIT OF A WORRY IF THE V8 S ARE NOT READY BY THE END OF JUNE,SINCE THEY WONT BE ABLE TO SELL THE 5.4 ANYMORE, DO YOU THINK THIS IS POSSIBLE ?

If you have nothing to ad dont post either, oh btw the caps button can be turned off too. And for your info no matter how often you get on here the Coyote power section is always on the main page.

[merlin]

I am already piecing together in my head a new XR8 - first mod exhaust to get the V8 note, then pulley to get the supercharger whine. Dark argents transferred off my current XR6T and lowered. Exciting times for Ford.

FG GT spec, yeah baby!

[Transfiguring R]

Cheers JPFS1.

Good bloody knews that, even if it increases the price of the XR8 some!

Makes it a bit more likely that the Pursuit and Super Pursuit might go, I'm thinking (NB: I can't remember if that has been confirmed or not yet...).

[Brent]

Hmmm. Sounds like Coyote will be a sweet engine in S/C form, but I wouldn't be popping the champagne quite yet for wildly improved 0-100 times. Wonder how many torque tags will be built into the engine management software to save drivelines?

This engine is more likely to shine in the areas of allowing better handling (less front end weight), rolling start responsiveness, and ease of day to day driving when at low to middling revs.

Fg's have different offset. You can put fg wheels on au-fg but not the other way around.

[Falcman0o7]

Some people are never happy.

I would have a supercahrged XR8 ANY DAY! i wouldn't care if it made 250KW! Give it to me!

Poor Ford...Even it's fans winge.
