Dual fuel, choice of petrol? With PULP I would go as high as 10:1 if you have good knock sensors.

Dual fueling?

With fancy spark control you could run upto 11+ish:1 higher if the PULP is only for starting/light running

without fancy spark control 10.5:1 is about the upper limit for normal working.

That limits you to only using PULP fuel or other high octane stuff.
