Hi all
Was at Snetterton today in my 3.5s, great day and weather behaved. Probably the last track day of the year for me :-(
Do have a couple of questions though, really am not technical or knowledgeable when it comes to cars so wondering if anyone has any thoughts on the below.
Firstly, when going out for a session the first few laps the car feels rapid everywhere but then I dont know, it just feels like it loses a touch of power. I did several trials today on the long back straight and on my first 2 or 3 laps I can hit about 130, right at the top end of 5th, before I need to brake for the corners. However, 5 or 6 laps into the same session and I can only get to about 120, coming off the prior bend to the straight at the same speed and really pushing but it feels like it has lost a tiny bit of top end. Is that normal ? Is that something all cars would suffer from ? As I say, no idea myself !
Second point, same as above, no issue for the first 2 or 3 laps but then afterwards I noticed that coming off a bend and accelerating, the car has about a second delay to really get going. It accelerates but literally takes a second, maybe slightly more, and then suddenly it accelerates like it should. This happens most of the time in 3rd but I can get it to do the same in 4th. Now it is always as I come out of a bend, so my head is telling me maybe the fuel moving around in the tank but then it doesn't do it for the first few laps. I always make sure I am out with a full tank as well so cant believe 2 laps can make that much difference.
As I say, not technical so hope above makes some kind of sense !!
Thanks all
