I think 2.9 is possible but will need warm tarmac traction and i guess i will have to up the revs further. I have had the circlips done so should be ok. My Stage 4 consistently takes either 3.4 or 3.5 secs to go from 60 -100 so with a 2.9 could be as low as 6.3 to 100 which would be pretty awesome, best so far is 6.6, still very good.
Trouble with this is that you cant really practice without drawing way too much attention.
Had a go tonight, but it's thrown up a couple of things that make comparison difficult.
Firstly, I am not running standard tyres. They are slightly down on grip but better on comfort. So a compromise. Can see me getting a 2nd set for track.
Secondly, how to compare conditions, road etc.. ?
Anyway. +15c tonight, overcast and windy. No one foot roll out.
LC: 0-60mph in 3.60, 0-100mph in 7.60.
No LC: 0-60mph in a terrible 4.07, 0-100mph in 8.32. Big delay in the first 5mph as the car thought about it, which probably wouldn't have shown with a one foot roll out. Then did a 2nd 0-60mph (with no 100mph figure) and got 3.75.
Clearly I am down on traction.
And this is a snapshot, not the best of a number of runs.
When I first got the car I got a 3.32 0-60mph on a warmer day with much less wind.
Will probably wait until later in the year and try again on a warmer road.
