Mustang SVO: Everything You Need To Know

February 2, 2021

Fox Body Mustang SVO

If you don’t believe in crystal balls but love the Mustang SVO, you might want to change your opinion on the unknown. The 1984 Mustang SVO holds a special place in the hearts of Mustang enthusiasts because it marked the beginning of a new era and it would provide an unequivocal glance into the future of performance cars in America. It was born out of regulation and raised in the era when performance and efficiency started to intersect in a way that was unheard of for the time but is seen as normal today. Sure, it didn’t put out bombastic, crazy amounts of power but it did equal it’s big brother's horsepower with a full 2.7L LESS displacement. So, it seems, there really is a replacement for displacement and the Mustang SVO was on the cutting edge.

This article will cover everything you need to know about the turbocharged 1984-1986 Ford Mustang SVO, including the below topics.

Why Regulation Drove Change In Performance Cars

There were a few major things that really brought the world of performance cars to their knees in the 1970s. First off, the massive oil crisis of 1973 made fuel not only extremely tough to purchase (long lines at stations were common) but also made fuel extremely expensive. Richard Nixon’s creation of the EPA would also drive home the fact that these ozone belching muscle cars were also no longer fit under increasingly stringent emissions regulations. The last nail in the coffin was the insurance industry’s war on muscle cars, led by none other than American safety activist Ralph Nader. Since muscle cars were primarily bought by young people, they could no longer afford to run the fuel swilling, expensive to insure beasts they came to love.

The muscle car was dead.

Ford, like all other American manufacturers, was reeling from the sales death of one of its most popular and profitable vehicles. In the post muscle car era, Ford struggled with unloved Mustang designs that offered none of the performance or attitude that the Mustang became famous for. More efficient European cars were becoming increasingly popular in the United States and the men and women at Ford were ready to go to war.

Enter SVO or Special Vehicles Operation Team, which was formed to do three things:

  1. Run all Ford motorsports programs
  2. Expand Ford Racing as a brand and establish a performance parts business
  3. Produce road cars


Mustang SVO Powertrain

Mustang SVO Powertrain Design and Specs

Under the hood of the Fox Body SVO was not a fire-breathing V8 but a diminutive 2.3L SOHC 4-cylinder that also did duty in the Mustang II and Pinto. Yes, Ford put a Pinto motor into the legendary Fox Body Mustang and it worked. Wonderfully. To bump up the power, the engineers from SVO utilized a trick that is now utilized in everything from CR-V’s to BMW’s: advanced, computer-controlled fuel injection and turbocharging. SVO pushed 14 lbs of boost to this basic engine to produce 175 horsepower and 210 lb-ft of torque. This made the 1984 Mustang SVO one of the most powerful American made cars of its day and cemented SVO as a force to be reckoned with.

A new water cooling system and additional fine-tuning would see a solid bump in power for 1985.5 and 1986 models. All SVO Mustangs utilized a Borg Warner 5-speed gearbox.

SVO Mustang Chassis Design

SVO Chassis Design

Sure, that turbocharged powerplant is something to behold but some of the best magic from the SVO was found underneath the Fox Body. Since the engine in the SVO was much smaller and lighter than the heavy V8 found in the standard GT, the engineers at SVO were able to move the engine back in the engine bay and behind the front axle. This had a hugely positive effect on weight distribution and overall chassis feel.

Ford completely revised the suspension geometry to make the SVO a true handling machine. To match this revised geometry, SVO also quickened the steering ratio to 15:1 and added in thicker front/rear anti-roll bars, a limited-slip “Traction-Lok” differential, fully adjustable KONI struts/dampers, and meaty 225 series “Gatorback” tires from Goodyear. Bringing things to a halt were upgraded 4-wheel disc brakes that were pulled from the Fox platform-mate Lincoln Continental.

The SVO Mustang instantly looked the part on both the inside and the outside. A HURST shifter operated the 5-speed gearbox and Ford even adjusted the pedals for easier heel and toe shifting. Optional leather adorned the adjustable sport bucket seats and leather was also found on the unique SVO steering wheel while additions like power windows, door locks also made an appearance on the Mustang. You could even get an optional, upgraded stereo system. These features were not typically found on compact American coupes of the era and were done in an attempt to persuade European brand shoppers over to the Blue Oval.

Outside, the uniqueness of this model was even more prevalent with the addition of two iconic styling elements: the bi-plane rear spoiler and the large, functional hood scoop. These two things instantly set the SVO apart from standard Mustangs and would go on to define this unique vehicle. Eagle-eyed muscle car addicts will also note that the unique taillights also made an appearance on 1993 Cobra - a distant cousin of the SVO.
