I started working at Ford now and I'm getting a great deal on a 2014 GT/CS. I test drove a GT and loved it. My goal for this mustang is to top out around 800hp to the wheels. Shouldn't be too hard since it comes with a little over 400. I already plan on doing pulleys, intake, exhaust, and supercharger. Any other ideas?

 

• Built Short-Block
• McLeod Clutch
• Tremec Magnum XL
• 2.8L TVS

800 rwhp isn't just something you can turn up the boost and expect your car to live comfortably for a long time. There's alot that goes into building a high horsepower 5.0 that is also reliable.

Good luck!

 

Pulleys? You need to learn a lot about these cars first and foremost. What are your plans for the car where you'll need 800 horsepower?

 

To impress his bros?

 

Is this for real

 

I believe these 5.0s can safely do 650 hp motor... Anything higher than that, your on borrowed time, same with the trans if u have a MT

 

Well, the 420 that they're advertised as producing is NOT at the wheels ... at the wheels it translates to something like 375 or so, depending on trans/dyno/weather/star alignment/whatever else you can think of.

To get 800 REAR-WHEEL HP and have the engine survive more than a week, you'll definitely need a forged bottom-end ("built short-block" like mentioned above), a big blower, new injectors, fuel pump (or boost-a-pump), and a killer tune.
As for the rest of the driveline to stay together reliably, an upgraded clutch/transmission/1-piece driveshaft/rear-axle-tube-welding, and certainly some suspension work, as the stock axle-hop will certainly break some things if left un-addressed.

But, like it's also been asked above, what are your plans for the car?

Street race/show-off, drag car, 9-second 1/4-mile street car?

You need to have a goal and attack the build accordingly.

800 to the wheels? better get around 25k up minimum for that job with all supporting mods young man!!!!!

 

Bingo.

 

They have an awesome under drive set up for the power steering

For that power level, you'll be replacing every drive line component and every suspension component

 

Better off starting with a GT500.

 

I would think the Boss 302 Platform should support that kind of power with the right setup except for the trans. I don't think you would need to upgrade too much else beyond Fuel Injectors and Boost A Pump, which would come with an appropriately selected kit, correct?

Could be a more affordable starting point than a Shelby

 

Thanks for brining up the Boss 302. I am going to yank this thread a little from the OP and ask another question. Boosted Bosses are putting down alot of power. Much more than the regular 5.0. Would swapping in the pistons/rods/crank from a Boss into a regular 5.0 suffice for boosted applications?

It seems like a good budget upgrade to "forged" internals.

 

Wish I had a job so I could buy a new GT

 

I knew that feel, bro. Good luck to you sir.

 

You know little about cars it seems as other have posted... 800 hp at the wheels is going to be alot of work. its comes with around 360 whp..

A intake and a supercharger??

 

 

800 hp??? Lol

If this guy wanted an 800 hp car, he wouldn't be on a basically newbie/ daily driver forum asking the likes of us asking how to do it. He'd already know for the most part.

 

Nope that should do it.

 

I think a set of axle backs will put you in the neighborhood myself.
