Gday
If I have 11.5:1 compression would i get away with using premium fuel (optimax,bp ultimate) and a top notch octane booster? or would i have to retard the timing still if say it was running on about 8deg btc?
thanks 4 replys

| I would lock your dizzys weights and only use the vacuum advance. This should stop the total advance before it start to give troubles. |
