Ok, now this thread is heading into the water meth realm too much. This is a Port injection gas/ethanol thread.If I were to install progressive spray water meth kit. Am I correct that I would only need one nozzle in a throttle body spacer? Does that harm or throw off the map sensor in the intake manifold? And what size nozzle should I use?
I suggest you read over some of the wonderful water meth (w/mi) threads we have.
Short answer, you need to supply enough meth to cover your hp goals, so it's situation dependent, please take those questions elsewhere though, I am keeping this gas/ethanol focused. We have a bunch of w/mi threads.
