Istvan brought his 2015 Dodge Charger SRT Hellcat in for the first round of modifications! And with a Hellcat, that spells 800whp, of course. Working with the existing aFe POWER intake system, Jackson installed a Metco Motorsports 2.75" upper pulley to get the 2.4L supercharger spinning a bit higher, along with a Gates green belt & Metco billet idler to keep belt slip in check, and addressed fuel supply with a set of Injector Dynamics ID1050X fuel injectors. Up next, Charlie strapped her down to the rollers so that Vlad could perform a custom dyno calibration via HP Tuners. The result? 800.21whp & 748.24lbft on 93 octane! Absolutely killer outcome!
