Use a 12 volt pump, a relay, Water solenoid or check valve, brass spray nozzle, and some hoses, clamps, and a Hobbs pressure switch. Do a search and you will find that you can set one up for less than $100 bucks total.

I see 100F drop with 8GPH 50% ethanol. This on a non intercooled 6PSI Vortech.
AFR 12.5 and 22* of timing, no KR. In my sign it was with 11 AFR without alkyl.
Next week I'll have a dyno session and I'll post the new numbers.
Setup: see my homepage - it's 100% homemade.

That's really impressive cooling! Eliminating knock with that much timing and a relatively lean AFR is very nice.
