Well we have 2 x 7s both 1.6K SS and both producing about 150 hp. One has the 6 speed box and the other has the 5 speed type 9 box.
The six speeder keeps the engine right on the boil because the top 5 ratios are all stacked close together. The first gear is quite tall (over 50mph possible in bottom) then the rest are all stacked. It's pretty busy though in the cruise and quite tiring if forced to drive on motorways for any length of time. The speedo is miles out but I think from memory it's around 4500 at 70 mph on 13" wheels with 185/60 profile tyres.
The 5 speeder has a pretty short first gear that I think is too low to be of much use. 2nd 3rd and 4th are the handiest making the car pretty much a 3 speeder if you see what I mean. The engine is much more relaxed in the cruise ie 5th.
Performance wise it's not quite as straight forward as you might think. Our 5 speed is actually the quicker of the 2 cars but it's pretty much stripped down and has no windscreen which makes a big difference when accelerating around 100+. There is not much in it though. The 5 speed seems to have an edge when the straights ask for another gear on the 6-speed near the end of the straight, but the 5-seed doesn't need to change up.
For preference I like the 6-speed best of the two because it is really slick to use and makes the car sound the biz at the same time. But as far as performance goes I think there's actually not much to choose between them. I drove our 5-speed back from Caterham this evening where it had been having TLC on it's front suspension after an ARMCO kiss at Croix last week. I thought the ratios made for very relaxed driving in normal traffic.
Edited to add that if Winky is reading this I got a very satisfying blast of flame out of the exhaust on overrun coming down the Caterham by-pass - thought you ought to know that.
