Thanks Peter! BTW impressive numbers on that Rice Racing webpage.
I am thinking of going the snow performance route. I am still in the air if I want to go 50/50 oir straight H2O. If I do run 50/50 I will tune it to about 11/10.9:1 AFR since my last set-up was tuned at 11:1 AFR at 14.5 psi and about 10* IGN Leading and 11* Split on just 91 octane.

With your compression ratio you will have no problems at all, you wont require much water if any at that boost level though it will be excellent insurance for you which is what its all about.
I run all my cars water injected, I hate turbocharged rotaries without it honestly. I have one customer in New Zealand who has been running my WI kit on his C16 8 sec drag car and he will not take it off due to his motor now running 3 times longer than it has at any time before and it sill has perfect compression. It transforms the reliability of these engines. As another example in my apex seal collection I have a set out of one car that I maintained for years and in that time it covered 55,000km at boost levels of 25psi to 21psi all the time and making honest 530bhp *engine power* and the apex seal height with right level of premix and WI was better than a stock motor that had covered only 20,000km with no chamfering or nay signs of abnormal wear. Should be compulsory on all Rotaries
