DTM CGI block was 20.4% lighter.
DTM CGI block used a bedplate design rather than conventional mains arrangement.
DTM CGI block had reduced deck height to accomodate a shorter stroke.
DTM CGI block had a revised cooling system:
Cooling channel around the bore was reduced in height. Cooling circuit within the block was changed from front-to-back, to an individual bottom-to-top flow around the bore. Coolant enters at the bottom of each cylinder and exits at the top.
DTM CGI block had a 4mm smaller bore-to-bore spacing and still acheived a 70% reduction in bore distortion due to the better properties of CGI.
