Shelby GT350 Intake Installed on 2015 Mustang GT, Here's What Happens on the Dyno

With Ford Performance also offering Shelby GT350 VooDoo engine bits and pieces as separate items, it was only a matter of time until somebody strapped these goodies to a Mustang GT's Coyote heart.

Here we are, talking about the first move of this kind, which sees a 2015 Mustang GT gaining a GT350 air intake and throttle body.

The 5.0, which comes from a member of the SVTPerformance forums, was strapped to a dyno, showing impressive top end gains. Nevertheless, before heading over to the video below to see the run, there are a few things you aficionados should know.

We mentioned the GT350 87mm throttle body above because this is required to install the $1,500 manifold, along with custom engine mapping.

This Mustang GT also packs a few other bolt-ons, including a Steeda cold-air intake, an X-pipe replacing the factory resonator, as well as a pair of Magnaflow mufflers. All the changes are managed by a Lund Racing 93-octane Flex Fuel calibration.

Comparing the peak values using the standard manifold and ECU mapping vs. the GT350 intake and custom mapping shows a 35 hp and 3.7 lb-ft gain. Nevertheless, if we are to analyze the top end area, the gain jumps to 55 hp and 39 lb-ft at 7,300 rpm.

Here's Alex, the owner of the 'Stang, comparing the manifolds of the 5.0 and the 5.2 V8s: "The real magic is inside this [GT350] intake, a little less precise, but inside both manifolds are the two support posts, on the Coyote, these look to be almost an inch in diameter whereas the GT350 posts look to be about 3/8. The runners where they meet the plenum are much larger in height. I managed four fingers wide with wiggle room on the GT350 whereas to get the same amount of wiggle I could only manage three fingers in the OEM intake."

The best part of it all is that the man claims the everyday drivability isn't affected. And while the Shelby GT350 intake manifold may have larger runners, it doesn't require cutting a hole in the hood or lowering the engine, as it happens in the case of a Boss or Cobra Jet intake.
