i took my ss camaro to 163 fuel shut off took a mazada 6 pos rental to 121 fuel shut off havent gone over 115 in the s yet

 

the mazda took forever we have it on tape we were in middle of desert 170 utah coming back from cali it took like 30 seconds to do 60-100 lol

 

I hit 176.4 in a 93 rx-7 r1. Crazy shite and I would NEVER do it again. heh
I got the s2k upto 140

 

My max so far is 160. I did this on I-99 racing a M3.

 

At 135 my GPS was at 133 which is a small margin of error IMO. Another myth dispelled?

 

i think most people have verified the speedo while on the dyno.... the dyno **should** be correct and will read one thing while the speedo often reads higher at the higher speeds.

There are too many variables....worn out tires are smaller than brand new tires...different brands of tires are different sizes even though they claim to be the same.....that alone could create enough difference at 150mph......

That is my $.02


do you have new tires / old tires? aftermarket 17" / 18" tires and wheels? stock tires?

Well all speedos are designed to overread at least slightly. As for those who've seen 160+ in the S2k their speedo is either overreading massively or they are on a long downhill stretch with a following wind. There is no way a stock S2000 will do more than just over 140 at best on a level road.

 

Sorry dude, on a level road, I had nooooooo problems at all topping out 5th, and half way into 6th. I pulled to 157 (although took a while) and had I had more room, would have broken 160.

 

i reached 264Km/h ... and thats it.... never tried again!

 

My car is completely stock with appx. 3000 miles on the stock tires at the time I was driving down the interstate verifying the speedo with GPS. I would have went faster but my passenger was more than a little frightened. I slowed down because I couldn't deal with the screaming.
