Rebuilt motor after hurting a piston and used dished pistons to lower compression for the change from nitrous to boost. Originally the motor was 11.4 to 1 static compression and after the rebuild was 9.5 to 1 static compression with custom pistons. Same top end...throttle body, intake, heads, and cam were used. Exact same exhaust was used as well 1 3/4" stainless works headers with off road mid pipes and slp power flow exhaust. Same camera used for both sound clips. Can you hear the difference?
