APS builds 557 hp twin-turbo setup for Pontiac G8 GT

APS is in the business of making power and that's exactly what they've done for the new Pontiac G8 GT and its Aussie-spec sibling, the Holden Commodore HSV. The tuner's Stealth Intercooled turbocharger setup uses two water-cooled turbos mounted deep into the engine bay, just ahead of the transmission, to ensure underhood temps are kept in check road debris be damned. According to APS, the system is a straightforward, bolt-in affair, utilizing a right-sized, aluminum, air-to-air intercooler, seven pounds of boost and a pair of TIAL 38mm external wastegates to bleed off exhaust gases and optimize throttle response. While APS hasn't installed the system on a Pontiac G8 GT yet, they've strapped its own blown HSV (with a three-inch cat-back exhaust) onto the rollers of a Dyno Dynamics dyno and produced 557 hp and 583 lb.-ft. of torque while running 93-octane. Pricing hasn't been announced yet, but considering how impressed we were with the standard G8 GT, this setup has the potential to redefine the bang-for-the-buck quotient in the segment.

6-7k

I will most likely be getting this or the Mag. SC kit for my G8 (when I GET my G8!)

But NOT for that price. Im hoping that it will lower to low 5's in the next 2 years when everything settles down.
