If you are like us and have salivated at the thought of marrying some of the new Shelby GT350 5.2-liter Voodoo engine’s components to the standard S550 Mustang, you’ve been looking forward to this modification for a while.
And thanks to M6G member Sandeale (Alex), the trailblazing soul who recently purchased and installed the intake manifold and throttle body of the 2016 Shelby GT350 on his 2015 Mustang GT, we now have insight into just how well the 2015+ 5.0L Coyote responds with the GT350 intake.
After some initial measurements of the difference in port sizes and cylinder heads between the OEM Coyote intake and that of the Voodoo, Alex installed the GT350 intake and noted the slightly over one-inch clearance below the GT’s strut tower brace.
It was now time for the setup to prove its mettle. Having already performed a baseline of the stock Coyote manifold, the beefed-up 2015 Mustang GT with GT350 intake was strapped to the same dyno and run with the same Lund Flex Fuel tune (93 octane) and modifications as that of the baseline dyno. To maintain as much consistency as possible, STD correction was used for both runs.
The dyno graph results above show significantly increased top end power — peak-to-peak gain of 36 RWHP and an incredible 56 RWHP gain at the car’s current peak of 7500 RPM!
