Default 2018 STI Reservoir Question

I have a 2018 STI and I bought an Aquamist HFS-3 because our fuel is poor and we can't get e85. I planned on buying a Howerton Engineering Twin-Tank but they don't sell them anymore.

I daily drive the car so I need to keep the windshield washer reservoir, what are you guys using for a water/methanol reservoir?

I can't figure where on earth to put the pump let alone a tank and that's in an Outback.

What about tapping into the wiper reservoir? That is my plan. The only thing is you'd have to use 50/50 for your wiper fluid... or regular blue 33% for your injection. Do they sell 50/50 at stores in Canada for your cold winters anyway?

Are you modding for more HP or just spraying to prevent detonation?

I liked the Howerton Twin Tank system because it was a complete mounting solution. You mounted the controller and pump on the same bracket and it was very tidy. I suppose I could tap into the wiper reservoir but I'd rather not because spring is so messy I am constantly spraying the windows to clean them.

I have never seen 50/50 water/methanol here but we can get close. I remember seeing -45* stuff once that was over 40% methanol but the norm is -40* that is about 40% methanol.

I am wanting to spray primarily to prevent detonation but I suppose some extra power would be a benefit.

Pick up some boost juice from Speed Factor. It's about 50/50 meth to water content or you can mix your own.

How about something like this for the tank? you can mount the pump directly to it. http://www.alcohol-injection.com/en/...mped-tank.html
