5.7 / 6.1 Hemi Camshafts

New XFI™ 5.7 & 6.1- Liter Hemi Camshafts COMP Cams®’ new XFI™ (Xtreme Fuel Injection) camshafts for Hemi-powered Chrysler vehicles dramatically increase engine horsepower and torque, yet retain compatibility with all OEM vehicle computer systems. Available in three different profiles (XFI™ 260, 268 and 273), the new camshafts are uniquely engineered for street performance and towing applications.

In recent dyno tests performed on a Chrysler Hemi engine (outfitted with COMP’s #26918 Beehive™ valve springs and upgraded exhaust), the XFI™ 260 camshaft netted 20 additional ft pounds of peak torque in lower rpm ranges and 31 additional horsepower. Stepping up, the XFI™ 268 camshaft added 14 ft pounds of torque at low rpm and 47 additional peak horsepower. Amazingly, COMP’s XFI™ 273 camshaft yielded it’s most significant horsepower increase (over 4500 rpm) generating 61 horsepower more than the stock Hemi 5.7-Liter camshaft.
