1290 Top Speeds...

...in the spirit of Hooliganism, whats the top speeds people have seen, heard about, done on a private road with Matrons permission etc?

So far chickened out in the mid 130's but there must be a lot more to come, whats the limiting factor aside from fore arm heft

260 kph (161 mph) on the clock and was still accelerating, although the speedo is very optimistic.

Not sure. but less then 9k. Still had plenty to go anyway.

240km/h GPS, still pulling hard. Not sure what the dash was reading as I wasn't looking.

216kmph was what the shift light flashed at during the running in period. Haven't pushed it since I got the service done.
