13 second AU six possibilties.

Don't know if i'll be one of them but it will be done.

No reason why it can't be a daily driver either.
I do 100k round trip every day, in the same trim as I ran my 14.38.

I agree. I think in 12 months time there will be a number of AU I6's regularly running 13's... then trundling off to do daily driving duties. Certainly expect there will be a few doing it by the end of the year too.

i so wish i was at least in the 13's... I know i have an ED, but an AU motor...

Apart from a cam, my motor is standard, and it loves it!!! I bet this time next year there will be a few more NA 6's in the 13's. There is only one E-Series (Apart from JMM) that is in the 13's... I'm next behind...

[Stav]

Nice work man..I know you will get there soon..

1 that we're aware of, i reckon there has been a few personally.
one i know of that isnt 100% confirmed, but its a big country

but still, out of the forum cars, its a very exclusive club!

[OED666]

not on fordforums, it doesnt count... just kidding...

BI6TIM knows of an EA in brisbane that runs 13.5... might have to line him up...

It's all in fun i suppose , but who is prepared to spend a bucketload on a 6 cyclinder and load it up to the max only to have it last a while before it needs a rebuild ! .

As others mentioned , you could probably get a v8 and work it lightly / for cheaper than what it would cost to get a I6 into the 13's / and have it running just as fast or faster than the I6, and it would probably last you longer too.

I think Jonbays was on the money with his quote about the AU being cheaper in the future , and use it for just a track car and remove the extra weight , then it might actually be worth looking at imo .

[rodderz]

With all this edit work, it gives different approaches and more scope for tuning, especially for auto's and putting in converter's. Until the last year or so this hasnt been available so I think it wont be long at all till an AU6 runs a 13. As has been said, mid 90mph is enough to run it for sure, just needs the driveline & suspension setup to get the launch and shifts right

[FS5]

i reckon it's only a matter of time before someone cracks a 13 ,if trypower is running a 13.3 with the stock xr6 cam .imagine what it would do with a bigger bump stick in there or possibly some head work.
it's all there we just need to find the right combination of parts/tune to get the job done .then our i6's will be cracking 13's

[Stav]

I really dont think that it will cost a bucket load to get these into the 13's at all. The problem is that a repeatable way has yet to come to our attention. Once it is done then there will be more at an affordable price. Just need a little better power,suspension,tyres and driveline. Most guys do get lowered suspension ,springs anyway.

The setup will be critical. Standard ba xr6t are quoted at 14.9 to 14.5 1/4 miles. These put out 185 rwkws on Spiros dyno and I put out 131 rwkws and am close to those times. 14.7.. Im missing 54 rwkws and still intimidate the standard ones.This illustrates how setup has a profound effect on how quick a car is.

Yes there is an EB in Adelaide that was cutting 13's about 5yrs ago from all accounts.

13's are not elusive. There are way more than a handfull of 13sec 4.0L's

Who? Also are they drivable?Are they street trim?

[OED666]

i am sure there is quite a few of quick 4.0L's... wish mine was one of them. At least 13's quick.

I think you need to have a atleast 98+ trapspeed to get into the 13's.

Rollin and I worked out that if the track was 20cm shorter, i could have done a 13.99999999... LOL

As JMM's car is proof, Suspension setup plays a major role

[DENKO]

i would love to break a 13 but its all bout the money, unless someone gets sponcered by a company, with discounts on parts and labour

I agree too. Daily driver, 13s six cylinder AU's are only just around the corner.

At the moment engine power is sitting at around 180rwkw NA.

I disagree with those power figures.

Current guys in the (very) low 14's are more like 150-160rwkw and about 96-97mph, and 60 footing around 2.0-2.1.

I reckon those running high 13's would be more like 170-180rwkw and 98-99mph, and 60 footing around 1.9-2.0.

Power is not everything. The first auto BA XR8 utes running 12's where doing it with only around 230rwkw...and thats before you account for the (questionable) relevance of dyno figures in the real world :P

More cam duration, and more static compression, as well as the usual bolt-ons and a top class tune aka Bluepower or G&D or even Croydons in Stav's case.

[FUZMOBILE]

guys, i reckon it is achievable also, need correct bottom end work, cylinders bored to 40thou over, with ultralight pistons, but the key is that you need a ef head, with bigger valve openings and ported to maximum allowable specs, also a custom cam grind for the head specs, will also need fuel delivery upgrade, then drive line needs a boost, definately shift kit and high stallie, balanced shaft, 3.9 ratio lsd diff, with super low springs, and medium soft shocks on rear, this machine would be a weapon. i reckon the setup would definately get into the 13 seconds.

[Stav]

The quickest i6 are running au heads.

[trick_xd]

I wish i was closer to a track .... OR even a decent Dyno all this talk im wondering how much power and speed i would have..

[Stav]

Hmm I am tempted to just do this. I think I can reach a 13 without much more fuss. In 12 months depending if I feel like it i will have the wagon into the 13's. Im not waiting for any body else or workshop to pull their finger out.Im gonna do it myself.

everyone has different oppinions on this, but i was told cam grind for ef head is easier and valve openings are bigger also.

[Stav]

I can tell you after looking at around 60 au heads that the ports do seem bigger in the au than prior models.Stokeb ran a 13.9 with au head.OED666 has an au engine and has done a 14.

[FTE217]

Dream on dream on dream on......

[Walkinshaw]

AU ports ARE smaller than 94DA heads. Fact

Stock AU ports, although smaller than EF head, they flow the similar. Same flow, smaller crossectional area = what ? ;)

Yeh I would agree the AUII WR02 heads do have smaller ports and don't flow as well despite having the same valve sizes as the E series XR6.

I don't know if its a combination of rocker geometry of the 1.8:1 gear and head but it does seem bloody hard to get over 150rwkw on an honest dyno with an AU. i think its all just enough to need a different cam strategy mainly but still working on that one so can't say for sure.

Either way I reckon an honest 185rwkw are needed to get a 1550kg AU into 13's. thats about 40 more than I have and I have another 100kg in the wagon to boot so mid 14's as good as it will ever get for me I reckon.

i was given this information, by someone that works on ford heads mainly and its his everyday business, so he knows what he's talking about, also the guy i bought the turbo kit off told me the same thing, "Use au block with EF head, best combo".

[OED666]

what about AU XR6 heads... thats what i have. i also noticed on my cam spec sheet that it has 1.7:1 Ratio roller rockers...

[FS5]

there are 2 different types of au heads ,as i found out after playing around with mine.ones a lot better than the other
oed i'd say its probably just a typo on your cam card.all au i6's including xr6 run the 1.8 rocker ratio.

Thats just surecam specs. The AU (& EL Hybrid) rocker gear is 1.8:1 ratio.
