AU (I, II, III) non-XR V8s

Pauly2's thread on EF-EL V8s made me wonder... what are the main differences between the AU's V8 models? For example does an AUIII Forte have a 175kw V8 in it? If so, does this mean it still comes with the E7 heads & possibly the HO manifolds?

Just out of curiosity...

Re: AU (I, II, III) non-XR V8s

With that power output I'd say yes E7 heads atleast...Strange the AU l XR8 was 185 kw but has GT40p heads..But better torque...This motor is derived from a truck...The good motors from Lincoln had long gone Mod motors..

Re: AU (I, II, III) non-XR V8s

So the AUI XR8 is more torquey than say the AUII (or even the AUIII?)? If so, very interesting... I could imagine an AUI XR8 with a 347 kit being a bit of a torque monster then!

All AU 5.0L (excluding some T series) had GT40P heads and Explorer intake - both a significant improvement over the E7s and HO.

Re: AU (I, II, III) non-XR V8s

So Ford might've underrated the non-XR range's V8s to make the XR ones seem better? Because by the AUIII you're looking at 45kw "on paper" difference!!!

I'm not too familiar with the hardware (and software?) differences either, so I'm assuming this "45kw" is an optimistic power hike with a factory "sports" exhaust and "sports" cam... Not degrading the XR gear (some of it I'd probably love to have in my EB), but 45kw is a rather large power hike!

Maybe the non-XRs have 55mm throttle bodies, 58mm MAFs, and the same tiny "crushed" extractors that stock EBs came out with, to keep power to 175kw?

I'm sensing though that the non-XRs are the sleepers of the range, not as far off from the XR8s as claimed on paper :p

I'm open to confirmation/correction/flaming!

Re: AU (I, II, III) non-XR V8s

All AU 5.0Ls used the Explorer manifold and 70mm MAF sensor standard where on EB - EL models they were only used exclusively for GT models.
The Series 2 EL XR8 was the only E-Series to get the explorer manifold and 65mm throttle body std, this along with 4 into 1 stubby extractors and ECU recalibration lifted power from 170kw EF - ELI XR8 to 185kw ELII XR8.

The biggest advantage with getting an AU is the GT40P heads, they outflow E7s even with a port job and just trails behind if bigger valves are fitted, but this is comparing a worked head to a standard one. With a port and polish the GT40Ps are that much better that they will outflow an LS1 alloy head with ease.

Re: AU (I, II, III) non-XR V8s

EB to EL models had 55mm maf...The E.L ll had Explorer inlet and may have had bigger 70mm maf...Most the electronic advances came from maf....

Re: AU (I, II, III) non-XR V8s

ELII XR8 had the 55mm MAF, and not even a 65mm T/B. It measures about 62mm, and in appearance, looks identical to a 60mm T/B. Looking down the throat, it is visibly smaller than an AU 65. Having driven and owned both EL II and AU I XR8's, there is no comparison, the AU has definatly more punch than the EL, even when they were rated at 185 each, although the EL was at 402nm when the AU was at 412. I would possibly suggest that AU I XR8's were underrated, seeing I can remember reading a Motor mag test, with an AU and a VTSS series I, with the 195kw upgraded motor, and the Falcon was quicker, so maybe.....
The only EL Falcons to have the GT40P heads were the ELGT, and the FBT. The XH XR8 utes run an AU engine, meaning there is no EGR, as per AU, but still were lumbered with E7TE heads.
