I am really thinking about getting probably an 06 GT and I would like to end up with about 500 hp. I am new to the mustang platform and have a general knowledge of the performance parts available. I would think that a full exhaust, headers, cams, all the bolt ons and a supercharger would get me to 500 hp. Is this a correct assumption? Also, how much would all of this put me out to get there? Any information would be appreciated.

Thanks

A cobra????

 

Maybe wait until next spring and see if a special edition is going to be coming out. A Cobra or whatever would put you almost where you want to be just leaving the dealership, right?

 

Kenne Bell already has a twin screw supercharger kit for the 3 valve F150. They said it will work with the 4.6 3v they are just working out the tuning on the VCT.
It should be out shortly after the 05 is introduced. Buy one.....install it......done deal.......500hp.

 

Yup, supercharger will get you up there quick. Just caught up to a guy that threw one on a WS6 T/A, dynoed at 480hp @ the rear wheels!

Then there's always nitrous...

 

Don't you mean NAWWWWWWWS! :R:

I haven't been keeping up on the 2005, as I don't have much interest yet, but since the 4.6 3V isn't going to have forged pistons, you'd better be real careful turning up the HP to 500 at the rear wheels, or you may be the first guy to blow his brand-new motor!

Why no interest? Waiting on the 2007 Cobra or 2007-8 Shelby Roadster..

 

Yes it would. It would have too, cam and a s/c? WOuld have to.

 

It has hyperuetetic (sp?) which I have been told are just fine. I've heard, that forged pistons are really overrated. People get them when they don't need'm.

 

Hypereutectic refers to the alloy, it simply means that it is beyond the eutectic point (point at which a certain % of A and % of B goes directly from liquid to solid (instead of liquid plus alpha => solid or liquid plus beta to solid)). Forged pistons can be hypereutectic too. Forging is not overrated, forging produces a superior surface finish, reduces the number of voids in the material and can be used to introduce compressive residual stresses that will help prevent cracks from propagating. I would be surprised if it weren't a problem to s/c the production engine and actually use any of the gained hp without problems. Mfgs do not want to spend extra money, for example, when the c5 came out I read that many of the internals were cast, because they could still handle 345hp and that was all they needed to do, corvette owners would be happy with that amount of hp, and any more hp than that in the then new ls1 would have dictated more money being spent on higher quality parts (pistons rods etc). I can't imagine ford building the 4.6 to handle 500hp with no changes being made to rods and pistons, and possibly other parts, it would be stupid of them to do so when 99% of their buyers aren't going add another 200hp. Of course, it would be just fine to add the sc and leave the rest stock if you never actually use the power.

 

forgot to mention, it may be able to handle more power, but look at it this way....the engineers that put it together had to build the engine to last for the duration of the warranty. More hp = more stress = more money and shorter lifespan. Again, if you do add the sc, and don't drive the car any harder than before it shouldn't be a problem.

 

What would be the fun in adding a SC and not driving it any harder? I guess I am just young. But what you are saying is that if I add 200+ hp I should probably get forged pistons/rods if I want the engine to last. I will probably drag the car some so I'm guessing it would be a good idea to strengthen the internals.

 

I don't think it would be much fun, but then again my dad has a corvette which he claims now runs mid 10 sec quarters (I disagree). I'm willing to bet it's never been through the 1/4, but he sure enjoys talking about how quick it is, and how it could in theory smoke all other cars on the road. I don't know what ford will use for internals, but I'm guessing soon after it is released there will be tuners figuring out exactly what needs to be done to accomplish what you want. I would check out kenne bell in a few months as they would be likely to offer packages for the new 3v 4.6. My guess is that the pistons and probably the rods will be some sort of cast or powdered metal part that while plenty strong enough to handle the 300hp and live up to warranty will be designed to do little else, that's just how business works, why spend an extra $0.47 per piece when you don't have to, it adds up fast when you mass produce. Also, there is nothing wrong with overkill, even if it can handle 500hp temporarily with the stock bits, if you can afford forged pistons and stronger rods why not get them? The blower alone is going to cost you a few grand, and if its only function is bragging rights or blowing your engine to bits it's a poor investment in my estimation.

 

You know, I've read all these posts, and I think the answer's obvious:

You need $money$ to get 500 HP in the GT.

Thank you, I'll be here all the week...

 

A 500hp GT sounds great, but would it be smarter just wait wait and see what the next Cobra will offer? I mean, after you spend all the dough on the upgrades for a GT, the cost might even out. Besides, I'm assuming that the Cobra will have reinforced internals to handle the extra ponies, which I'm guessing will be 400+.

Opinions?

 

Exactly. I think you need $ to buy a Cobra.

Starting from 300hp and trying to achieve 500hp is going to cost a lot of cash. I would just use the money to buy a higher model that is designed to handle the power.

I wouldn't buy a GT if I planned to take it up to 500hp.

That being said, many people do it and if its your cup of tea, go for it. Just be prepared to loosen your purse strings.

 

Righto Hippy!!

For a GOOD example of cost-cutting in use now, look at how many new cars do not have passenger key holes. If a $4 lock cylinder is worth skipping, why would you build motors with forged internals??? , it is NOT cheap, by the way. A forged crank, rods, and pistons(called a rotating assembly kit) costs about $4000 for anything decent and that is just the parts mind you. Your other enemy is compression. Getting good NA hp by going to 9.7-1(and using 89 octane) or even 10.5-1(requires premium) is NOT forced induction friendly, regardless of the materials used in the engine. Why build a low compression motor just so 2% can put a blower on it? Too much boost on a fully forged high-compression motor will still destroy it.

So many people do not properly tune their cars and just keep sticking bolt on after bolt on on it. There is PLENTY of hidden power through a good valve job and porting, the proper exhaust(not every one adds power either, catless exhaust will yield a loss of power on a 2v 4.6 for instance), intake breathing, all properly MATCHED and TUNED does wonders. Add other goodies like the right gear ratio to better utilize the powerband(after tune and mods), lightweight flywheels and driveshafts, and you can make a heck of a difference without stressing the motor AT ALL over stock. About 2/3's of "hot rodded" Stangs are not properly utilizing their mods, or have them missmatched.

Its like what us boaters say(and its 100%true)- The CHEAPEST way to make your boat go 10mph faster is to BUY another boat that is 10mph faster.

 

The other thing that cracks me up is this: "I cant afford the extra 190.00 a month for a cobra!!!!

Cant afford $200 extra a month? But can afford at least that in monthy mods out of pocket, a $4000.00 supercharger kit(out of pocket), $1500 in brake mods(out of pocket), 500 for gears(out of pocket), $2,000 in suspension mods(out of pocket) $2000 in wheels and tires(out of pocket) $800 in various intake mods, throttle bodies, headers; a $800 exhaust, springs, castor plates, subframe connectors, bushings, new K member, body kit, interior upgrades, seats, shift kits, ect ect, and STILL get beat by a stock Cobra????

Its funny these days how so many people still try to buy cars with 1985 car payments
