I am currently running WMI as well. Using dual CM7 nozzles on the charge pipe, the kit I had purchased came with a single CM10 nozzle, but from prior research I decided to purchase two 7's for better atomization.
I have it setup just as Burger Tuning has it laid out, I went with Burger's kit as I have JB4 and setup and install was a breeze. I was running a 100% methanol when the summer heat was in full swing and was very happy with how it performs. It is setup to come on at 10psi of boost. The FSB controller does the rest of the work.
It is a bit dangerous, I had a "mishap" at the drag strip during a 3-4th gear shift, where I believe some Meth had pooled and caused a backfire in the intake manifold, virtually splitting it in two and ruining my night. I have since been using a 50/50 water/methanol mix with mixed feelings about it, the instantaneousness (if that is a word) of the power when injection is happening isn't what I remember it feeling like on 100% Meth. I blame myself for going with 100% off the bat, as I could only be let down after mixing water in with it hahaha.
But, here in Canada, there isn't much of an option for e85. The only place it can be purchased locally is at a speed shop, otherwise I am faced with an hour and a half drive to get some. By the time I would have returned I would be at a half a tank of fuel. As well, speed shop e85 is at a premium as well.
Drive-ability is virtually unphased, mind you it is quite tempting to lean into the throttle to feel the sudden difference in acceleration. When first installed I was using about a gallon a week. But the cooler months are here now and on the road usage of it isn't a requirement for fun (iat's sitting around 42f) so it is turned off for the time being.
Also, considering the cost at which it takes to outfit your car to be e85 ready, methanol is a cheaper option. The overall benefits are not the same, I get that, but cost-benefit wise it is a viable choice.
