How Ford could have made 500hp naturally aspirated on the GT500.

Some folks here are saying it can't be done, a naturally aspirated V8 making
close to 500 hp at a price point very close to the 2007 Shelby GT500.
Neither side can offer proof, yet, either way. I'm surprised at how rude
some posters can be because some person dares offer a different opinion
then theirs.
(I'm curious what happens on the job when their boss disagrees with them).
Yet, they can't provide proof (just opinions) that it can't be done.
Maybe it can't, this is just bench racing ....we're not talking life or death
stuff here or insulting your family members so learn to be tolerant...you'll live
longer and be way happier.
I'm interested in hearing from engineers, builders and designers that have
actually worked on clean emissions engines that have gotten high hp per
cubic inch and get their expert opinions.
Someone wise said "The fun is in the journey".

You need to get down off the soapbox and actually absorb what the guy was saying. Cause lemmie tell you something. Other makes may charge more for their quality, but they're financials are also a lot healthier than Ford's. That tells me that people are willing to pay more for quality - even if you're not.
Better get ready for an onslaught of powerful Japanese supercoupes, too, cause they're coming; beginning with the Nissan GT-R (Skyline), and it will DESTROY the Shelby in any contest (and don't talk "mods" to me). Will it cost more? You bet. So will the forthcoming V8 powered Supra from Toyota. But guess what, I betcha it will sell more units in the US than the Shelby. So, so much for the theory of "volume trumping quality and technology."
Ford needs to stop trying to be everything to everyone while catering to the lowest common denominator of the biggest possible market - instead, they need to focus on quality, customer service, and design and engineering innovation. It's the only way to get back on top and change perception.

I suppose someone would care to explain the logic, advantages, applications, and the differences between the thirsty 427 and the s/c 5.4.
I always thought the main purpose of muscle cars was being as inexpensive as possible as to allow us lower class, which happens to be a market of its own, to afford a fun means of transportation.

I think the proof is in the fact that in the past 45+ years of perfomance cars, no one has made a production car with 500hp for as little money as Ford is doing right now.
Off the top of my head, here are the 2007 model year cars out now with 500hp or more.
1. Ford Shelby GT500 (43-49K)
2. Chevrolet Z06 (65-80K)
3. Dodge Viper (95-100K)
4. BMW M5 (82-87K)
5. BMW M6 (96-102K)
6. Mercedes Benz SL55(130-150K)
7. A lot of Mercedes Benz AMG cars, starting at 140-200K
8. No reason to mention the exotic's like Lambo, Aston Martin, Ferrari etc.
It sounds like you have high hopes for this car, but you wish it were something that it isn't. If you're part of the very small niche market that wants a high performance Mustang that competes with the above cars, you may be better off building it yourself.

Whether it’s called the Nissan Skyline GT-R or just the Nissan GT-R, the 2009 model is expected to cost $75,000 when it goes on sale in the U.S. in the spring of 2008.
It will be coming onto the market right as the GT500 stops production. At 30-35K over the price of a GT500, it seems to be more of a Z06 fighter than a GT500 fighter. I'm sure Ford is flattered that you can even compare the two cars. This car is still a rumor for US production, but atleast they have a prototype to show, unlike the V8 Supra.
A V8 Supra in the US is only a rumor. When comparing cars, please try to use cars that exist.
I once saw a documentary of making a car and one car engineer said a major part of his job was 'protecting car buyers from themselves'. Dreams sometimes get in the way of reality.

Chrysler's 6.1L Hemi puts out 425HP (SAE)
Australian Ford NA 5.4L DOHC puts out 389HP.
GM's 6.0 LT1 and LS2 (corvette and GTO) both put out 400HP.
Even in race engines such as the 2000 Cobra R (NA 5.4L/385HP), and FR500C (NA 5.0L DOHC /~425HP), Ford hasn't been able to break the 500HP mark with a NA V8.
I know I've only used American/Australian examples, but I think 500HP from a NA engine at a reasonable price is still a tall order for Ford or anyone else.
EDIT: Or is it? See below.

Ok just to argue the other side for poops and grins (and after remembering this V10 experiment).
Ford engineers did develop a NA 351 C.I. (5.8L) V-10 in 2003 for the experimetal Boss 351.
http://www.motortrend.com/roadtests/...eleration.html
http://www.50mustangandsuperfords.co...ang/index.html
It's rwhp was 425-430 on dynojet, which comes out to somewhere between 475-495 at the flywheel. It was built by a "handful of rogue engineers" at Ford mostly using existing parts.
1/4 mile, sec @ mph 12.88 @ 114.44 (MotorTrend) and 11.93 @117 (5.0 Mag)
So there you have it. Ford already created a ~500hp NA engine and has already tested it in a Mustang. It can be done using mostly existing parts which I would guess means it could be built for a reasonable price.
And for less weight:
The Boss 351 used a 2003 Cobra body. The MotorTrend article lists the curb weight of this Boss 351 at an est. 3565lbs. A 2003 Cobra weighed 100lbs more, and I would guess that a 07 GT500's engine weighs more than a 03 Cobra engine, so a NA 5.8L V10 in the GT-500 might shave off 100-200lbs.
Ford could have put a lighter, slightly less powerful, NA 5.8L V10 in the GT-500 but chose not to.
Case closed.

this is an all-new engine that is most accurately visualized as a 4.6 Cobra short-block with two additional cylinders grafted on, and topped by similarly stretched Cobra R DOHC heads, resulting in an all-aluminum V-10 of surprisingly compact external dimensions and manageable weight

Hear that sound? It's the clue train, last stop you.
THESE COMPANIES DON'T CARE ABOUT PUTTING OUT THE MOST POWER POSSIBLE.
If they were trying to put out the most power possible we would be buying 1300rwhp cars off the show room floor. It's not like it's a big secret how to get big power N/A. Any idiot with wrenches can make a 700hp small block these days. It's nothing. The companies are just trying to sell you a car that you want to buy, nothing more. Stop looking into this as hp vs displacement, that's a ricer argument. You're looking way to far into this issue. It's all about making money, not competing with each other.

The GT-R is NO LONGER rumored for US production - it is definitely coming.
You are correct about the Supra V8 being only a "study" right now.
The point is that the Shelby will very shortly be outgunned by the imports in the one category in which it hopes to excel: performance. But you're right, it's "cheap." So three cheers for that!
Oh, no...wait, you're wrong. There's those pesky dealer markups.
Bollocks!

And for the record I am a huge Ford fan, especially the Mustang. Since I was little all I ever wanted was an early model Mustang, then when I was old enough to legally drive and Ford came out with the body style change in 94 I set my sights on that, and I got it (on my own). And when I heard of this new style I again wanted it and got it (again on my own). I have owned and driven many cars (including Audis and Porsches) and although I can buy pretty much any car I want, the ones I keep around and will forever are my stangs, I am currently looking for a 67 fastback to restore and will be purchasing the next body change in 09, and while other cars I own may come and go, the PONIES will always remain in my stable.

I will not get into the skyline and supra arguements for it is not only completely off topic, but also a completely moot point since they are still only in their concept phases and we do not know what they will officially be releasing here in the US, I have heard so many things on these cars and it keeps going back and forth on the motor alone, none the less the HP ratings. We will just have to cross that bridge when we get to it.

I would also suggest that things have changed dramatically in the almost 10 years since Toyota made that decision about the last Supra: witness all the high performance automobiles (foreign and otherwise) making a sudden resurgence in the past few years. Toyota may have been premature, and I think the Supra's dissappearance was only ever a temporary circumstance.

Here is the latest info I have heard about any GTR, it was as of July 9th:
2006 Nissan 350Z GT-S Concept
"A small team of Nissan development engineers working in their spare time transformed a 350Z into a highly tuned ‘Saturday Special’. Called the GT-S, the supercharged super coupe is a performance-focused version of Nissan’s acclaimed ‘Z-‘car’ and is designed to appeal to enthusiastic 350Z owners who simply want more.
Its first public outing will be at the Goodwood Festival of Speed (7-9 July) where it will join other exotic road cars in the Supercar Paddock and on the famous hillclimb course.
Although boasting a power hike and a substantially modified chassis, the GT-S is far from being a stripped out racing car with a rock hard ride and a peaky power delivery.
Nissan’s Communications Director Wayne Bruce says: "The GT-S has been created as a real car not an ornament.
"We wanted to build a ‘Club Special’ that could still be used to commute to work during the week but would provide added thrills at the weekend: a weekday workhorse and a weekend warrior in one distinctive package."
The project’s technical leader Steve Robbins – who during the week is a senior engineer in the new vehicle evaluation team at NTCE – gathered together half a dozen like-minded enthusiasts to work on the project.
Working after hours and at the weekend, the team members came from within NTCE and also from outside suppliers and was known internally as the S-Club Seven.
The principal changes made to turn the 350Z into the GT-S center on its engine and chassis. Using a supercharger installation from Swiss manufacturers Novidem, power has increased by more than 25 per cent from 300 bhp to 382 bhp, while torque rises from 260 lb-ft to a heady 314 lb-ft.
Performance gains are expected to include a one second cut in the benchmark 0-60 mph time (5.8 seconds for the standard 350Z) with 2.5 seconds slashed from the 0-100 mph time.
And it sounds better, too, thanks to an electronically controlled by-pass valve that enriches the exhaust note at a pre-determined engine speed.
NTCE engineers have undertaken the suspension changes. Working closely with specialists from Bilstein, the changes concentrate on optimizing road performance, with improvements in both handling ability and ride comfort, particularly on British ‘B’ roads. Wider wheels and tires complete the chassis alterations.
A wind tunnel developed body/aero kit from German firm Strosek not only gives the all-black GT-S a distinctive look, but also improves the 350Z’s aerodynamic performance with increased front and rear downforce at speed. The package is completed by a NVH pack which makes the GT-S even more civilized than the standard 350Z.
Steve Robbins said: "We could have produced a *****-out racer with huge power outputs and very little suspension movement. But while this would have created a superb racer, it would have been virtually unusable on the road. Instead we approached the GT-S from an engineering stand-point with a view to creating a 350Z that provides more of everything: performance, handling, looks, comfort and excitement.
"We also looked at the possible marketing potential of such a project and have designed the improvements as individual ‘packs’ – an engine pack, a suspension pack, aero pack and so on – and kept a close eye on costs."
So will the GT-S ultimately become more than a weekend project by a group of mavericks? Nissan is saying nothing officially, though insiders point to its appearance at Goodwood as a sign the company is giving the GT-S concept serious consideration."
Configuration:
Front Engine/RWD
Engine:
Supercharged V6
Displacement:
3498 cc
Horsepower:
382 bhp @ ---- rpm
Torque:
314 lb-ft @ ---- rpm
Max RPM:
7200 rpm
Transmission:
6-Speed Manual
And with this info it looks like Nissan is taking a cue from Ford and lowering the HP to cut costs so it can be affordable to a wider target audience so they can sell more, because at that power rating there is no way anyone would pay 75K for it (at least I hope not), so much for your theory of people rather paying for quality over value, and so much for the GTR being any competition.

I actually responed before reading your discussion about the GTR, however I still havent heard anything confirmed about it being built and which company name it will be under, if you have concrete info Id be very interested in reading it. Everytime I read anything about it or hear about it it keeps going back and forth so I have not heard any concrete info on if it is a go or not, at least no here in the states.
