i remember when I was looking for a cobra . When I ask question about the cobra on Facebook . Most answer are, “ look like this cobra has been beat on “ stay away “ I try to keep my cobra mint as possible , from time to time I do drive the hell out off it ( just to make sure the tune still work ) and once in blue moon I do a racing with friends . I never take mine to red line . 5500 rpm is max I ever go Is what I’m doing normal ? Or consider as hard drive owner that beat on the cobra .
