now I know roadster's are faster....lol.... stock....well, sort of, I had just installed the code 3 pulley, and a single NW CAI...but she hit the 160 backed off a little, and I let off at that point...as it had cut out breifly...my buddy right next to me was speechless until 55...his next statement I will never forget...."those telephone poles look just like one at that speed, I have never been over 120, and you just hit 160....I believe the 158 is correct, and momentum carried the speedo to 160, but it is what it is...I don't worry about it anymore....I had help with the road that evening with a couple of deputy friends from that county who live on that stretch of road...they were playing with their new LIDAR, and an older RADAR units...and they verified it as well...regardless, what impressed me about this car, was this happened from a dead stop to that speed in 9/10ths of a mile...as we measured the distance with the car's odometer where I let off...amazing little car for no engine work...not many today can match it...
