GT-R on low boost...
It did 190mph on it's last run before it got shut down...they notice coolant coming out of the exhaust. It seemed to be running ok but they didn't want to do a bandage fix at the track and have something small be catastrophic. Engine is apart now and they are taking a look at the source of the coolant and any damage...plus they are doing some Turbo work to make it a bit more efficient.
They think it had about 2-3 more mph before the coolant started leaking...
