Thanks for the lap times Bruce , on track the Simpson car was obviously the fastest and they were still having electrical problems Sunday morning but got them sorted.....Jeffs car was also obviously quick, I would imagine your car would post similiar times. The search for the Waggot head proved fruitless I guess thats why it is the holy grail of grey motor hot bits.I think one of the cars there Carey's car may have had one on it at some stage but now has Repco x flow. The Sunday racing was exvellent with so many grey powered csrs on the trsck at once.
