Jeremy brought us his 2008 Dodge Challenger SRT8 to have the 6.1L Hemi put under some pressure and to get it over the 500whp mark!
Modifications performed below:
• Whipple Superchargers Stage-II 2.9L W175AX twin-screw system
• Custom fabricated K&N Filters air-intake system
• NGK Spark Plugs LZTR7AIX-13 spark plugs
• JLT Performance 3.0 air/oil separator
• Siemens Deka Fuel Injectors 63 lb/hr fuel injectors
• MSD Performance fuel pump voltage booster
• AEM Performance Electronics UEGO wideband AFR gauge
• AEM Performance Electronics X-Series oil temperature gauge
• AEM Performance Electronics X-Series water temperature gauge
• HP Tuners unlocked ECU
• All the miscellaneous OEM and aftermarket components to bring it all together.
With the mechanical work wrapped up in the shop by John, Matt strapped her down to the rollers for Vlad to perform a custom calibration via HP Tuners. With the Whipple 2.9L delivering ~8psi, Vlad increased the 6.1L's output to 517.55whp & 517.82lbft! Some solid numbers considering the conservative boost levels!
