8500rpm in 4th gear changing to 5th? car would be doing ~220kph or so based on stock gearing. Don't think so, also gear changes are very slow and launch is very mild. Driver skill is more important than power, i raced an XR6t at WSID and was neck and neck with him the whole way down, not because my car is fast, but because he couldn't drive for shizz. When on boost he would pull a bonnet ahead then change gear ever so slowly and i would reel him back in and it would go back and forth to the finish line where he ended up doing 1 tenth quicker and only 3mph faster.
