geez...we aren't in high school anymore....videos, gps...lol...gps is off as much as a speedo is...I am working on a place, but liability insurance, and a waiver, and other legal issues have to be worked out. I had a passenger when I did 160, and it has seen the 150 mark many times since...hell, even Johnny saw 135 on less than straight bit of road. And, Steve...ISP does NOT use the Brickyard...Plainfield IN is where our police academy is, and there is a track there, but no long straightaways for high speed runs...As for "citing" from youtube videos, that is a myth as well...I have over 30 yrs in law enforcement and only videos I have ever seen lead to prosecution have been idiots that vandalize something and video it...with their faces plastered on the video...lol...as stated above, 6100-6200 rpms, with give you 186...but wind, road surface, and other factors will and do say WILL slow the progress to 186...HP...will help, as the MORE HP you have the sooner you will get there....
