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.
