I'm sorry, but I wasn't sure where I should post this question.
I was wondering if anyone has experimented with allowing the water/methanol mixture to disperse into a larger area to get better distribution between cylinders.

I have 2 questions. Is it a good idea to try something like the WRC cars, as in the picture? (I know they use these volutes for other reasons)

How would I test such a system for effectiveness?
Aside from waiting for one piston ringland to let go, is there a more scientific way to address and test for distribution? I can only think of EGT gauges at each port, which I likely dont have the resources for.

What are your thoughts on the efficacy of this? It seems logical to me to aid in the dispersion of a water/methanol mixture.

On an subrau engine, it is not as critical as all wmi fluid have to be redistributed at the small satellite mainfold that branches into four intake runners.

The uneven thermal-load due the turbo loacation and the length of the exhaust port runner is bigger concern. Front left cylinder is the hottest.

I you`re really worred about correct distribution you can go for runner/port injection.
