Orange Fury 2018 Ford Mustang Shelby GT350 – 500whp

Ford | Mustang : August 17, 2020

Around this time last year, Eric brought us his Orange Fury 2018 Ford Mustang Shelby GT350 for the first of a planned series of modifications: a custom dyno calibration, which netted him a ~15whp & 12lbft gain, coming in at 490.75whp & 408.01lbft. And for this step, Eric brought her back in to address exhaust restriction with a set of long-tube headers!

Up first, Alex removed the factory manifolds and installed a set of 1.825" primary OD long-tube headers from Stainless Works connecting to the factory exhaust system, and topped off the installation by welding in a set of Gen-2 UHO catalytic converters from GSport. From there, Matt strapped her down to the rollers for Vlad to dial the Voodoo 5.2L back in via HP Tuners. The results this round? 510.07whp & 432.03lbft, a gain of 19.32whp & 24.02lbft with very similar conditions to the runs last year!

Pretty solid results considering this car still has a stock intake system in place, and would see an additional 10-15whp with a JLT Performance system. That, paired with an E85 calibration, and this Voodoo would be pushing up into the mid-500s naturally aspirated! Both forced inducted or naturally aspirated, these cars are just fantastic.
