What makes a Mustang GT have more horsepower?
What makes a Mustang GT have more horsepower?
Aftermarket injectors have a different nozzle to better atomize fuel (giving you more power and more miles per gallon to a degree). Perhaps even more important than that is how much fuel and pressure they can handle.
What kind of pistons does a Ford Mustang GT use?
Ford chose hypereutectic pistons for the Mustang GT. They work well up to 450 flywheel horsepower. If your goals exceed that, you’ll have to upgrade to a set of forged pistons. Quality forged pistons are generally made of 2618 aluminum alloy, and include 4130 chromoly wrist pins.
What’s the horsepower limit on a 1999 Mustang?
On all 4.6 based engines though, the weak link is primarily the connecting rods. For 4.6 engines with 2 valve heads (2 valves per cylinder), the power limit is around 400 rwhp. This is for both NPI and PI models (1996-1998 and 1999-2004).
What kind of crankshaft do you need for a Mustang?
The stock crankshaft is a cast-iron piece and is good on applications up to 500hp; anything over that and a forged steel crank is in order. These can be found used as they came stock in the Cobras and can handle 1500hp when cleaned up and machined. The forged crank is a must for any serious build.

What’s the horsepower limit on a Mustang 4.6?
4.6L Mustang Engine Power Limits. The power limit on the 4.6 engine can vary based on the production type and year of manufacture. On all 4.6 based engines though, the weak link is primarily the connecting rods. For 4.6 engines with 2 valve heads (2 valves per cylinder), the power limit is around 400 rwhp.
