In race conditions it's 369.9 by Pizzonia in Italy 2004.
I think with DRS and a great exit on the final corner, it could be beaten..
As you say.....
The historic circuit is dubbed the 'cathedral of speed' and it holds the records for the highest speed - 371.7kph - recorded by an F1 car, the fastest ever lap, the quickest grand prix in history and the closest finish, with just a hundredth of a second separating the first two cars back in 1971. In the Italian Grand Prix 2004, Antônio Pizzonia of BMW WilliamsF1 team recorded a top speed of 369.9 kilometers per hour.
