135mph on spooky M+S rated tires. I could have gone more but backed off. Now i took the ram air hood off and put 3.73 gears in. I probably will ony hit 110 now, but havent tried in awhile.

On the Highway.
Dont see too many Cop cars in the UK so not much risk of being caught. Hence the average speed on the highway here is about 90mph.

I have had my needle pegged more than once. I have a 240 kph speedo (Im Canadian!) in my car and she would still pull after that. My guess would be 250-260 kph??
