I was driving along the highway this evening and I decided to go all out. I have a 2000 Civic SI. I was in 5th gear doing about 185km/h and revving at about 5000 rpm. All of a sudden it sounded and felt as if the car just died. Is there a limiter on the engine that prevents it from doing a certain speed??? Also, will my vtec kick in when I am in 5th gear and doing more then 5500 rpm???
