In the States there are a few guys that swear that meth is suitable for all comp ratios, and even works better with lower comp engines. Their reasoning is that as you use twice the vol of meth as ULP some of this ends up in the chamber and takes up volume thereby increasing compression ratio.
I'd run it with 10.5 : 1, you will be amazed by the mid-range torque increase.
I'll try to find some more info for you later, will post it here.

im only running like 7.5.:1 comp and since putn it on methanol the engine has come to life and runs cooler but only works well this low running boost
little different with EFI
its just a quick computer chip change n switch on the second fuel pump
so make sit easy to swap between fuels
