It just seems that my jump from 3.45:1 to 3.64:1 was fantastic. The jump from 3.64:1 to 3.9:1 is even greater tho but obviously the opposite way - can't help feel that it will run out of legs and on track I will be changing gear all the time. Getting to top speed will be rapid no doubt but I'm not interested in flat out top speed - corners stop that anyway lol.
