MPG on a blast

[ozonehostile]

i think the hdi box is longer across the whole range while the 405 box only has the longer 5th, so unless your on a flat motorway it makes no difference. i never realised 2100 was low, ive always thought that it could do with either a very long ratio 5th or a 6th gear, but there you go, now i know better. people often forget how much of a difference wheel/tyre size choices make when it comes to acceleration/mpg performance. like all the golf boys who put 19" rims on a car that orginally came with 15"s then wander why all the acceleration has gone....
