1. A flojet pump LF12222 series.
2. Most water/alcohol compatible pumps do moy like oil.
3. It will depend on the charge temnperature and ambierny temperature. In most cases, you uonly use a smal amount of water on a pre-turbo setup.
4. I think ~75-100cc/min per 100hp is quite effective on 108 octane. 100-150cc/min with lower octane. (M50:W50 mix)
5. We normally based on fuel flow:
- 100% water = 10-15% to fuel ratio
- M50:W50 = 15-20% to fuel ratio
- 100% methanol = 20-25% to fuel ratio. (requires fuel trim)
1 GPH = 3.85/60x1000 ml/min
1 LPM = 60x3.85 GPH
