That is pretty close then . Because I made three passes and got a 10.1 a 10.8 and a 11 according to my chart a 16.7 would be a 10.75 1/8 so I'm right on track of that. But there is no way I'm a good enough driver to get testing type times?? Mayne my straight away is angled downhill Haha maybe that's why it was slow one way and faster that other.
