Mate's saying run the beast on the highest octane possible cause it will run cooler. Highest I can purchase here in New Zealand is 98 octane. (without race license which I do not have)
Note it states 90 Octane or higher in Clymer manual.
If its true it runs cooler the higher the octane how does that actually work ?
(Is the explosion more efficient ? Would have thought been hotter)
