5000 RPM with 205 50 15 tires with stock ZD is 97 mph according to my excel spread sheet (which has proven to be around 4 mph fast).
6500 RPM is 126 mph. Thats pretty quick! |

This has a variety of calculators in it (Microsoft Excel):

I would guess that it was about 108mph.
My Speedo was reading 120. It felt really fast though.... (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif) |
