Stock Block Shock
Anthony Santora built a shockingly powerful S550 with ProCharger boost

We know that Ford engineers are focused on creating cars that hit a performance target, handle well, remain quiet and stay within budget. Building a factory performance car like the Mustang is a huge challenge. And, working under that pressure must develop a cautious nature.

While working on a voluminous story about the then-forthcoming Coyote engine, we can still vividly remember engineers saying this engine was already tuned for maximum performance and it wouldn’t withstand boost. As we now know, it thrived on boost (to a point). Then those same engineers were pushed to push the engine platform even further with the Boss 302, 2015 Mustang and Shelby GT350.

Certainly the Coyote 5.0-liter in the 2015+ Mustang is more robust than its predecessor found between S197 shock towers. However, we never expected owners to push that platform to over 900 horsepower. Of course, that’s just what Anthony Santora, of Santoras Tire & Exhaust, did with his Oxford White 2015 Mustang GT. Watch it in action right here…

To produce that kind of power, Anthony was one of the first to adapt ProCharger’s larger F-series supercharger for the S550 platform. That required some customization of the bracketry and tubing to make things work. With help from ProCharger’s Erik Radzins, he was able to science-out a solution that worked.

“I chose ProCharger because there is nothing original anymore or I should say, no originality,” Anthony said. “Every Mustang goes turbo. I wanted to go a different route. After tremendous research there was no way to go other then ProCharger. It is the best of the best.”

In the end, the F-1 and Coyote were a match made in horsepower heaven. Anthony’s car belted out well over 900 horsepower at the tire.

“… I was hoping for around 800 to 900 horsepower,” Anthony explained. “After having some issues here and there. It turned out awesome. We actually just switched fueling again to Ignite E85 and are sitting around 930 rear-wheel horsepower.”

That’s a crazy amount of power from a blown stocker, and it’s apparently quite docile on the street—until you turn off the nannies and let her rip.

“Times are different; Especially with the help of Lund Racing and their incredible smarts and expertise. This car I can drive anywhere I want. It has cruise control, navigation, and every option. No worries,” he said. “Yet. I can put it in race mode, turn off the AdvanceTrac and just let it rip. Being able to drive to any track, run or grudge race anywhere, and then cruise home is an amazing feeling.”

While Anthony is obviously stoked about the progress of the project so far, he hopes to prove it out further on the drag strip. He plans to put the first drag laps on the car this weekend at Maple Grove Raceway during the NMRA Motorsport Nationals in Reading, Pennsylvania.

“I plan on doing a built, sleeved motor this winter, switching to an F-1X and aiming for 1,300 rear-wheel horsepower,” Anthony added.

Nines with a blower and a six-speed would be quite an accomplishment. It’s definitely a performance pinnacle that’s well beyond what the factory engineers saw from their Coyote engineering, but it sure is fun to watch people push the stock parts to unforeseen levels.


Anthony’s 2015 Mustang looks clean rolling on five-spoke Welds, but the massive ProCharger Stage 2 intercooler gleaming through the grille is a clue that this S550 puts down some power.


Under that MMR Roadrunner intake manifold is a stock Coyote 5.0-liter engine boosted by a ProCharger F-1 supported by a Stage 2 HO air-to-air intercooler, a Fore Innovations fuel system, and a Lund Racing calibration. “Was also one of the first cars to run the F1 setup when they released the S550,” Anthony said. “I had to make all custom piping and change the bracketry to fit. We worked with Erik Radzins of ProCharger back and forth to get the setup right!”


If you are going to rock a vanity plate like this one, you better have the goods to back it up. Anthony’s 2015 Mustang definitely has the performance to take on those Brand X challengers. You can’t see it in this shot, but when necessary the car is equipped with a Custom Chute Mount by Santoras Tire & Exhaust/Performance and a Simpson parachute.


Anthony’s ride definitely has street cred with a leather interior and navigation. He did add a few extra Auto Meter gauges across the top of the dash so he could keep tabs on the fuel pressure and air/fuel ratio that are so critical to keeping a stock Coyote alive at this power level. He also upgraded the driving experience with a GT350 steering wheel and dropped some weight with a rear-seat delete.


There’s just something classic about a white Mustang rolling on black five-spokes. To run these drag wheels on his ride, Anthony was one of the first to convert to smaller rear brakes to allow for a 15-inch wheel. He worked with Rey Rivera at Juggernaut Racing and the people at Weld Racing to work out the one of the first such conversions for a 2015+ Mustang.


How’s that for a stock-motor power curve? With a ProCharger and the necessary supporting hardware and tuning, Anthony’s 2015 Mustang rocked the rollers to the tune of 906.98 horsepower and 669.55 lb-ft of torque. Recently, he tuned it up on E85 to over 930 horsepower at the wheels.

Very nice ride. He better put a timer on that MT-82. I hear a Magnum XL in his future.....

Amazing! The big question I have is how the block is staying together what with all the broken cylinders we saw in the older Coyotes? The '15 block doesn't have any extra reinforcements in the cooling jackets.

it won't live long if your constantly pushing that kind of power.

same thing happened to our 15 block, we were running mid 9s til the water jackets let go. never did hurt a piston or rod, but the block just isn't capable of living at that power level for extended time periods (actual time on the car)
