Hopefully, someone will have some answers... I'm #1 on a list to get the new Dodge Charger SRT8, and while the HEMI will propel this full-sized beast at velocities close to the new Mustang Cobra GT500, I want MORE! What can be done to a new-generation HEMI to increase HP and torque? Cold air intake, exhaust, chip? I'm not going to re-do the engine (new cams, etc.). Any suggestions appreciated.
