That is exactly what happened to a friends YB, it was never mapped for top speed and after hitting the limiter in 5th it had a meltdown.
Euan, why has this thread been started again ?
i recall stu giving the reason about cossies diying at top speed runs because of fuel starvation due to poor pumps and stuff due to the pump not being able to supply enough fuel to the rail for a sustained high revving time
and he posted it about 3 times and everyone's answered in different threads
