100% Water, anyone making power?
Good info on the different mixes ^^^
For the Aquamist 2d pump its recommended to be put closer to the battery for optimum power. If you have an EVO8 its easy, you can use your intercooler tank and pump. Have the pump be a priming pump giving you an additional 10% of flow to the RACE pump (about 500cc) you can run 1 .8 and 1.4 nozzel or 3 .4 nozzels.(which I do)
All this can be installed in the engine bay and the tank at a 50/50 mix should last 2-3 weeks. 50/50 mix will be your best bet, as recommended by Richard from Aquamist and by myself from countless hours trying different mixes.
If you have a hard time getting meth. Go to your local Autozone and ask them to order their own valuecraft brand of -20 windshield cleaner (blue) its a 45/55 mix (meth/water) and works great and is cheap for 6 gallons ($10-$15) Good luck!
