Those are great mods. I run a similar setup. Consider adding a Magnuson 2300 Supercharger, Bosch 1050 Fuel Injectors, dual fuel pumps, Methanol Injection. A good Dyno Tune can really achieve big power across your power band up to 6500 RPM. An E85 conversion will also help a lot, just make sure your fuel system can handle the ethanol and meth. I have a 2009 Pontiac G8 GT that I purchased new in 2009. After Dyno Tuning my G8 makes 715 HP and 625 ft. lbs.Torque. It is a beast! I hope you enjoy the last great high performance Pontiac! Thank for the great video!
It needs headlight eyelids.. great mods on the g8 import.. I'm not sure if you guys can get otr cold air intakes in the states but it pretty common here in Australia on the G8/ ve commodore... I run a wagon with a g8 front bar that I grabbed from the plant before it closed down
