Ok so I know my speedo is around 10% off due to the tires...

tires are 205.50.15's Falkens...

Speedo was 5000 rpm in 5th gear (stock) I could have gotten it up to 6500, but there was a lot of traffic....Holiday weekend...

SO, how fast was I going???

oh yea, it got there quick!!! This sucker revs like stink..thanks Jake!!

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!

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)
