12.731 for a second launch is awesome maybe the smaller turbo's are stronger down low.

Car feels quicker than my SS commodore 6sp which run 177km'h over the 1/4, think 80-120 was around 3 seconds so i'm hoping for around 182km'h providing i can get traction in 1st gear.

Tried a tune'd F6 80-120 in 2.1 has run 11.7 in street trim.

Should be at Calder Park for the next street meet.

The car has managed a 2.64. From what I've seen it's probably around .03 to .05 sec slower than an F6 and that would be mainly accounted for in the second gear 100 -110 area (above 5500 rpm).
On the subject of the launch affecting end speed, the data I've seen shows it has a surprisingly small affect.
For example in my earlier post (3 pages back at 7:10 pm on 17/7) I mentioned the almost 2 tenth 400 metre time effect that a 2 tenth faster 0 - 40 time would have (12.84 down to 12.65 sec). However when I use the Racelogic software to calculate the end speed difference, it comes out at a miniscule 0.04 kmh.
On the other hand not using enough revs or hitting the rev limiter (particularly in second and third) can have a significant effect on end speed.
To make sure that my car used maximum revs , I drove it more aggressively than normal (harder acceleration, kickdown) for a while just before getting to the track.
I wouldn't try driving manually, too hard to get the timing right.

2.1 and 11.7 are great times for just a tuned F6.

On the subject of your own F6, when you ran that excellent 12.29 on the ET street radials how much weight was there in the car.
Driver weight, fuel load spare tyre etc.
