thats interesting to know. I have never had mine on a track and I have never really tried to see how fast it could go, but I have hit 100 very easily on local roads and it always seems like it could easily go much faster when I let off
I have read that they have the top speed limited, but I do not know if that is true or just speculation
The 115 MPH was not the top speed of the N/A sling. I believe it was the top speed on that course before he ran out of straightaway and had to turn and let off.
His point, the charged sling accelerated faster in the same distance to get to the speeds you see in the video.
