    2011 Shelby GT 500 - No more Iron Block

    Bummer for the tuning IMO, the block is not sleeved either. The GT500 could put out more power than the Ford GT on stock internals due to the iron block. The weight was a killer... but this thing was solid rear axle anyway, not exactly designed to be nimble to begin with and the weight savings are only ~100 pounds:

    With a little more power, a less weighty engine and new performance upgrades for 2011, the folks at Ford's SVT performance unit continue to turn the once portly, push-pig Shelby GT500 into an ever-more-legitimate all-around performance car.

    Like its V6 and GT brethren, the GT500, which the company is to unveil at the 2010 Chicago Auto Show, gets substantial upgrades for 2011, only a year after a major overhaul for 2010. You can think of it as a preemptive strike against the Camaro Z28 that has long been rumored to be waiting in the wings at Chevy.
    Not surprisingly, the 2011 upgrades for the GT500 begin with the supercharged 5.4-liter V8, which Ford describes as an evolution of the engine from the now-departed Ford GT. Yep, that means the GT500 now has an aluminum-block engine instead of the stout iron block it has used up to now. This little switch chops off 102 pounds from the burden carried by the front axle of the notoriously nose-heavy GT500.


    Meanwhile, the cylinder bores of the aluminum block are not conventional iron sleeves but instead have been coated using a plasma-transferred wire arc process, saving further weight. It's the first time Ford has used this process in volume production. A composite coating some 150 microns thick is deposited on the cylinder bores, reducing friction and saving 8.5 pounds compared to conventional iron liners.


    That the engine now makes 10 horsepower more than last year's supercharged V8 now totaling 550 hp ain't so bad either. The horsepower boost is thanks largely to a retuned exhaust, which Ford says also provides for a more aggressive sound than the old pipes. The new motor makes the same 510 pound-feet of torque as last year's version.


    The engine also adds a larger two-row intercooler for the supercharger, offering 40 percent more cooling capacity to help the engine make more consistent power at high ambient temperatures. (This had been a weakness of the 2010 engine.) Oh, the GT500 no longer is subject to a gas-guzzler tax in 2011 thanks to a 1-mpg improvement in both city and highway cycles, now up to 15 mpg city/23 mpg highway.


    The other big news on the performance front is the availability of a new Performance package for 2011. It includes new forged-aluminum 19-inch wheels up front and 20-inchers in the rear. These handsome wheels (pictured here) carry the next-generation of Goodyear's Eagle F1 SuperCar tires, now called "SuperCar G: 2." These tires are "as close as you can get to a racecar tire," according to SVT technical specialist Eric Zinkosky. The 265/40R19 front tires are wider than those of last year's 255s, while the 285/35R20 rears offer the same tread width but are larger in diameter by an inch. The Performance package also includes uniquely tuned dampers and front springs that are 20.5 percent stiffer than those of the base car. The rear springs are only 9.5 percent stiffer, so they're relatively soft to improve traction under acceleration. The ride height has been lowered 11mm in front and 8mm in the rear. The Performance package also brings a new 3.73:1 rear-axle ratio.


    Besides the wheel and tire package, you'll recognize the Performance package cars by a unique Gurney flap on the rear spoiler, narrower "over-the-top" stripes on the body and the lack of stripes on the shift knob. And if you look close enough, you might see that the new shocks are painted red. Ford says that the new Performance package should result in 7 percent shorter braking distances compared to the 2010 car and a 3.0-second quicker lap time around its 2.3-mile test track.


    The standard car if a Shelby GT500 can ever be considered a "standard" car gets some improvements for 2011 that make it a bit easier to live with. There's more acoustic insulation applied to the instrument panel, plus additional sound-absorption material behind the interior trim panels and rear wheel arch liners, all in an effort to reduce road noise. Like the V6 and GT Mustang convertibles, the GT500 convertible's structure has been improved. Stiffer crossmembers, added gussets, a front Z-brace (which connects primary and secondary crossmembers) and stiffer A-pillars have improved lateral stiffness by 12 percent, according to Ford. For 2011, the convertible also now wears standard 19-inch wheels.


    Like the lesser Mustangs, the 2011 Shelby GT500 will have electric power steering in place of the 2010 model's conventional hydraulic boosted system. We have yet to drive a Mustang with electric power steering, but we're hopeful that it doesn't mess up what was pretty damn good steering.


    There will be more optional niceties on the 2011 model as well. The optional glass roof is now offered on the GT500 coupe. All GT500s come with standard HID headlamps. And, should you be foolish enough to allow someone else to drive your GT500, the 2011 model comes standard with Ford's programmable MyKey system to limit the car's top speed.

    Sweet, but with the new 5.0 coming back, making ~412hp, adding an S/C with exhaust will be great bang for buck.

    Ford's engine blocks, in order of strength:

    5.4L

    1) Ford GT: T356 construction, with 1" or more meat around cylinder bores this is a true race casting capable of holding 2000HP+. 6 bolt mains. Block weight: 104lbs

    2) Ford non-NVH Fe, as used in 2007-2010 GT500: Cheap and strong, however the bores will distort at 1440HP destorying the motor. Info from John Tymensky former Ford powertrain engineer that saw said motor ingest itself on an engine dyno at Ford. 4 bolt mains. Block weight: 181lbs

    3) Ford NVH Fe, as used in 2003+ Lincoln Navigator/other applications: Same basic construction as the non-NVH block but with 24lbs of additional mass around the bottom end/mains. Unfortunately the extra material down low doesn't help with bore distortion, so it's rated at the same 1440HP, despite being 24lbs heavier. 4 bolt mains. Block weight: 205lbs

    4.6L

    1) Teksid Al block, used in 93-early 2001 Ford 4v Modulars: John Mihovetz/Accufab uses a slightly modified version of this block (stud girdle) and the stock 4.6 Forged crank making 2300HP+ in his NHRA Pro Stocker. IIRC he's in the low 6s@220-230 these days. 6 bolt mains. Block weight: 77lbs

    2) Ford 4.6L Fe Block: As used in the 2003-2004 Terminator Cobras, they share basic design with the 5.4L Fe non NVH blocks and are also good for 1440HP. 4 bolt mains. Block weight: 177lbs.

    3) WAP/Windsor Aluminum Plant block, used from 2001.5+: A less expensive and domestically cast Al 4.6 block, good for 900HP in most cases however some have cracked at 700HP. Block weight: 74lbs.


    Stock forged 4.6 cranks have gone as high as 10,000rpm and made as much as 2300HP (after being properly prepped), they are fully counterweighted 4310 steel.

    Stock forged 5.4 cranks are missing a center counterweight and are good for a "paltry" 1400HP and 8800rpm, again 4310 forged steel.

    Here are a few pics of my old Ford GT/Block/Head N/A 5.4L/4v. 15:1 static C/R, 550rwhp@7500rpm, 360rwtq from 2500-7500rpm, with a custom cast 6" runner intake manifold.


    A Ford GT head (used on Al Papitto's 597rwhp N/A 9.2@145 @3200lbs 97 Cobra and my old 550rwhp Open Track 5.4L 4v) flows around 310cfm/260cfm @ .500" and 28" stock, 370cfm/290cfm after the same full hand race port and Serdi 5 angle VJ with hand blend. 5.4s use tiny 37mm/32mm valves on a small and severely undersquare 3.55" (or in this case 3.57") bore with a monstrous 4.165" stroke.

    The Coyote, 5.0L N/A motor with just a tune (on 93) makes 450HP at the crank. Click here to enlarge

    It can take boost, but being that it's related to a 4.6 (bore spacing) just with a slightly larger bore/stroke a standard 4.6L block will still be able to stand up to more pressure--more gasket sealing area and meat between bores keeps rings happy.

    There was a dude who shoe-horned a 5.4 navigator motor into a foxbody coupe chassis. And turbocharged it, I think it was a T88 if Im not mistaken. He was the cover of muscle mustangs and fast fords a couple years ago. I have that edition, 700 whp like nothing. Car has beautiful brakes too and supposedly gets tracked. A properly built foxbody is hard to beat for the money, which is why I own one. Click here to enlarge

    I googled but couldnt find it. The details I do remember because I read the article. I can find the magazine and even scan it for you lol.

    The car was a yellow fox coupe with cobra R rims, lowered with big ass baer brakes I believe. Full suspension and chassis work with cage.

    5.4L 32V navigator motor dropped in and turbocharged. The car is making 700 whp on pump gas I believe, capable of more. I believe it has A/C too. I clearly remember the engine bay, the 5.4 modular engine is enormous compared to the 5.0 or 5.8 Windsor smallblock. The heads of a 4 cam OHC engine are very tall, thus making it hard to fit between the shock towers.
    Anyway, the guy did it and it made it to the front cover of MMFF.

    Csticky, now do you understand what I was trying to say on n54tech? It is not always the larger displacementhighest flowing heads that win. Ultimately it comes down to the actual block/bottom end strength. I'm curious weather the s65 or n54 will be able to take the most power, fuels being equal. We will not know for quite a long time though. This is posted on phone at doctors officce so please excuse typos and grammar errors.

    The S65 block will take more power, aluminum-silicon composite from the former F1 foundry, same material as the F1 blocks.

    I still don't see us exceeding the limit of either block any time soon.

    the n54 block is open deck, the s65 is closed or semi closed at least im sure. that right there says a lot for which block will be able to handle more power. as for the con rods and pistons thats a different story. i know there are aftermarket manufacturers for pistons and rods in the n54, i havnt done any research on the s65 aftermarket internal bits so i wouldnt know.

    Open deck you say? Learn something every day. End of story then.
