The 2005-10 V6 Mustang featured some much needed performance upgrades over the previous OHV 3.8L V6 Stangs; however, Ford still left plenty of room for improvement. Modding your V6 Stang for performance might be laughed at by many Mustang enthusiasts; however, owning and driving a V8 powered Pony car might not be in the cards for every S197 Mustang owner. That is why so many aftermarket companies have stepped up to provide V6 owners with plenty of performance modifications to help eliminate the performance gaps between the GT models.

4.0L V6 Mustang Specs:

  • Horsepower: 210 HP @ 5300RPM
  • Torque: 240 ft-lbs @ 3500 RPM
  • Fuel Economy: 17/26 MPG
  • 245 cubic inch displacement
  • SOHC with 12 Valves (2 per cylinder)
  • T-5 Tremec 5 speed manual Transmission or 5R55 5 speed Automatic
  • 7.5” Rear End
  • Single exhaust outlet

There are plenty of YouTube videos and forum post of very quick 4.0L V6 Mustangs. I have even seen plenty in action at the drag strips and open road course. When starting a performance based build with V6 Pony Car it is best to start with a plan. You need to decide if you are looking to create a performance Mustang that will be mainly used for street driving, drag use or open track racing. Having driven a few of these cars and experiencing the “short-comings” in person this is my recommendation for starting a 4.0L Stang project:

  • Air & Fuel Improvements: Cold air intake, SCT Tuner & possibly throttle body
    • The foundation to any performance build is to help your engine breathe easier. The first step is to add cold air intake. A handheld tuner from SCT and throttle body will help you maximize your air/fuel performance.
  • Engine: Under drive Pulley Kit, coil pack & ignition wires
    • An under drive pulley kit and a performance coil pack will help you get the most performance out of your V6 engine. It is also a good time to upgrade and do some maintenance. Replace spark plugs, plug wires and fuel filter.
  • Driveline: trac-lok, rear end gears or 8.8” swap
    • Installing a higher ratio set of rear end gears such as 3.73 or 4.10 will be one of the most drastic improvements to your acceleration. Due to the lack of 7.5” rear end traction-lok and the high cost of the Auburn limited slip, many V6 owners opt in for the 8.8” rear end swap. This swap brings many performance and strength benefits. You will need the SCT tuner to change gear ratio in your S197 Mustang.
  • Suspension: Rear control arms & lowering springs
    • If you have followed my upgrade plan, you now have increased rear wheel hop due to increased power. Adding a good set of rear lower control arms will help you plant your newly found power to the ground. It is also a good time to get rid of body roll with a set of lowering springs and replace worn out suspension components.
  • Exhaust: Dual Exhaust conversion & GT rear bumper
    • Some like to start with the exhaust, but it is proven to do little as far as performance. It is more about improved exterior looks and sound. I would save this for the end. You will need a GT or GT500 rear bumper or valance (for 2010 models) to get dual exhaust openings on the rear bumper.
  • Wheels: Drag wheels or Drifts
    • Wheels are completely up to you. If you are going all out for drag racing check out some of our SVE Drag wheels. If you are looking for something that is more for street/strip use I would look at a set of wider and larger diameter such as our SVE Drift Wheels. This one is all about your personal taste.

In no way do you have to follow this step-by-step. If you would prefer to do these upgrades in a way that better fits your personal goals – go for it! Matter of fact, please feel free to comment below and let us know what you have done to your V6 Mustang! You can also post up pics of your ride as well!


V6 Mustang Air/Fuel & Engine Upgrades

A proven way to get more horsepower and torque is to add cold air intake kit to your Mustang. Intake kits remove the restrictive factory intake box, filter and tube. It replaces them with a high flowing components that allow your engine to get more air which means more power! Companies such as BBK, Airaid, Ford Racing and Roush all make performance cold air intake kits for the V6 Mustang. Check out our selection below. When doing any performance mods to a S197 Mustang a SCT Tuner is almost always a must. It allows for custom tunes, rear end gear ratio changes, data logging and MANY more features. If you want to maximize your intake system, don’t forget to add a performance throttle body from BBK.

V6 Mustang Driveline Upgrades

Driveline mods for your V6 S197 Mustang can be some of the most “bang for the buck” performance modifications you can do! Installing a limited slip differential and higher ratio ring and pinion set in your 7.5” rear end will produce better acceleration and improve your launches at the drag strip. Speaking of drag racings, don’t let the sloppy factory shifter ruin your quick shifting abilities! Check out our short throw shifters specifically for 4.0L V6 Mustangs!

V6 Mustang Dual Exhaust Conversion Parts

Nothing says American muscle car like a dual exhaust system on your Pony car! Adding a true dual exhaust system to your 4.0L Mustang V6 requires a few parts. The outcome is a performance exhaust system that gives you a more horsepower and a deeper more aggressive tone. The key components you need for a dual exhaust conversion are a mid-pipe (H or X Pipe), dual over axle tail pipes, 05-10 GT/GT500 axle back mufflers and GT/GT500 rear bumper cover. Don’t forget to add a set of performance shorty or long-tube headers to maximize performance!
