[QUOTE="superpsd, post: 1015071, member: 15821"] Also another note. There are whipple upgrades for the GT500s M122 that range from 2.6 to 4.5L of displacement. A 2.6 flows 1400 cfm and a 4.0 can flow 2518cfm so there's many choices to cure any lack in airflow. The 4.0 also has a maximum speed of 18,000 rpm. [/QUOTE]
