I used to keep it in 3rd in the NA and hit the limiter just as I passed the line. But you are running quicker times than I used to.
P.s gottago have you not hit somewhere in the mid 12's before i am sure you need to hit fourth to be in the 12's at around the 175-180 km trap speed...i could be wrong.... :br::br:
super duper fast forth gained me some mph as i was just smashing the limiter for far too long in third.
Even with 26" dia rears, I still needed 4th, to run low 12's - I was on the border where I would run only maybe .1 or .2 slower if I stayed in 3rd, but my trap speed was way lower.
My best time was done by leaving it in 3rd and banging on the limiter, however selecting 4th at high rpm is very difficult in my car (shit synchros + gearbox oil). She gets to the limiter a fair bit before i cross the line so by the time is gone over the line its already cut out 6-7 times. Oh well, changing the gearbox oil, got new tyres and putting an SAFC on....... we'll see what it does then.
