Back to my last Thursday test, I must add that never ever before I had tested kick down AND sport mode!

I'm still amazed by the result: the car started like a bullet and never ever before I had overtaken so fast! For me it's mind-blowing: it was impressive. And what a noise: not that disturbing inside for such a short while but I don't know outside...

And I'm pretty sure that 2 elements have played their part: E85 and mainly the additional holes I've drilled in the bottom of the air box (and don't forget the full SS derestrictive exhaust line). I had immediately noticed the enhancement, the engine answer being far quicker after the airbox mod. Now it's absolutely immediate and the rising in turns is massive. I'm chuffed! But I should be cautious on our next journey next Tuesday: radars are spying everywhere...

Moreover I was wondering in which gear I may have been when overtaking at 101.4 km/h (63 mls - actual GPS speed) and 6410 revs.
Here is the answer (sorry, the page is in French but figures are hopefully international!):



So the answer is: 2nd gear!

But as my gearbox is automatic and then managed directly by the system, I assume that the engine will never be allowed to trespass the 6,750 revs limit exactly as it happened last Thursday: 6,410 revs.

After all provided it should not last too long, it cannot be damageable to the engine going up in the revs from time to time. Apart at that moment, it didn't go up over 3,700 revs, which is pretty decent and secure.

Last remark: it's good as well to be able to notice that both VIS motors are working so fine!
