i know it is not a U13 but my U12 bluey used to make it down the quarter in 13.8secs with a 60 foot time of 2.2 secs or something like that....
i was impressed with that as anyone would be with a barely modded bluey....
now at the time it was producing about 120-130kw's at all 4's, am a bit unsure as didnt have it dynoed at the time, but now my beast has 145kw's at all 4's as tested at technik tuning on the last dyno day in Melbourne. i am putting it on a dyno dynamics dyno in a week and a half's time to find out if these new mods have done anything so will have a new power figure to put up aswell. if you want bluebird check out the thread in vic and tas meets etc. and come along or something.
and since you want to go to the drags, we will be going to the drags on the 18th November at calder aswell, i will be punting mine down the line so would like to punt against another attesa ehhe
and will be interesting to see what 172kw's will do (my estimate at a high 12).
have fun
