Element Hydramist universal instal

[Mazda Carnage]

Mixture suggestions? I planned on running 50% methyl hydrate and 50% water but my main goal is detonation prevention at high boost and high rpm (*) to much timing advance on the factory ECU

Any one have any jet size recommendations?

The car is a Mazda Mx6 GT 2.2l, 12V Sohc 7.8:1 compression, running stock ignition maps (OBD1), I have no timing control, * red line/rpm cut is 6200RPM, peak torque torque hits between 3000 and 3200 rpm .
It runs 4x 330cc injectors and 2 extra 670 cc injectors (before the throttle body)fuel economy is average 16.5 mpg or 14.26L per 100km (after 68 fuel ups) .

I estimate (goal) between 325 and 350 whpr which would also make 450+ftlb torque.

The Elemental Hydramist installation for the Subaru 's states .9mm and .8mm below 350 whpr and .9mm + 1mm above 350 whpr, I was thinking 2x .9mm might be the best balance between the two, but my cars not a Subaru, the engine and ecu are primitive by today's standards...

The car runs 21lbs of boost regularly but I did blow an engine once at the track at that boost I plan on running 18-19 psi without the water/meth injection and 22-23 with the water meth system running, however if I can safely run a few extra PSi boost at the track I will.

This is the engine/set up the kit will go on:
