Water / meth injection with rootes blower

I have the stage 2 on mine. I originally had it on a single carb smaller supercharger and worked great. I have the same kitt under to 750 dp carbs on a 6-71 that's set up for full throttle before it comes on. I still haven't had my foot to the floor yet. And I have it on a 50/50 mix. But can change it up a bit as I can get methanol by the gallon jugs.
