Devilsown Methanol Alcohol Water Injection - View Single Post - Wrong Aplication for Solenoid Valve or Product Problem

Thanks for the help.

I am already running your pro. con. off the map sensor. It works well for the vaccum side of it. Other then I would rather see a start duty cycle of 50% instead of 15% for my aplication thou.

I have a very radical engine (260psi cranking pressure) 50/50 water meth on top of the stock fuel table will not stop the detonnation when running 87 octane fuel.

I run a minus 15% in the power enrichment table thus giving me about a 50%/50% mix of 87octane gasoline and straight methanol in the mid rpm range. This is why I need stages triggered by rpm.

I had great luck today by orienting the valve direction, lower the pump presure switch setting as low as it would go (130psi) dead headed, and rewiring the solinoids that when the pump is on it always has at least one path for fuel flow wich lowered line pressure to around 100psi.

The valves are isolating fine at this pressure even if they were never designed for it. I had them backwards in the begining.
