Our ECO-POWER project has moved further ahead than we ever imagined – uncovering all sorts of fascinating facts and discoveries that throw a whole new light on how to make our engines perform better with greater economy and lower emissions – but as we learn more we realise it would have helped to start out slightly differently.
We should have conducted more data tests on standard road cars before then moving on into our Eco engine versions and now not only have various other models of capacity conversion under test, but also two 996 ECO-Engine'd cars (one manual and one tip) that we are testing and gathering data on.
There is a limit to how many cars we can apply to this and how much time we can spend just driving them around for data acquisition – so it would be a big help if some of you could post on here the following for standard 996 3.4's or Hartech 3.7's.
The reason is that we have found that gearing has a major influence on economy and emissions and the chosen gear seems to change and depend on the torque characteristics of the engine as much as the preferences of the driver – so is a major factor in power band development.
(1) We are only interested in results at constant speed – i.e. 30, 40, 50 ,60 and 70 mph (usually in traffic) and would like to know which gear (manual or tip) you are most often driving in when at the above constant speeds.
(2) We don't need multiple answers saying sometimes this gear or sometimes that gear - but just need the gear you most often use at those speeds.
(3) Secondly (if it is not too difficult) which gear you usually drop down to when accelerating from those same speeds (or the same gear you usually stay in).
(4) The answers to Q 1 can be posted for example – like this Manual (or Tip) 30 – 4th, 40 4th, 50 5th, 60 5th, 70 6th.
(5) Q2 the change down (if used) when accelerating - could be (Manual or tip) 30 – 4th to 3rd, 40 – 4th to stay in 4th, 50 – 5th to 4th, 60 – stay in 6th or down to 5th.
(6) Please don't copy these figures I am interested in your own.
Finally a very happy New Year to all.
Many thanks guys, Baz
