New to forum / Custom WI system for AUDI

[Richard L]

Thank you for for clarifying the accumulator.

I belive you have include a 22cc accumulator on your order already. It should be with you anytime now. Those accumulators are air charged, see diagram:




We have always install an accumulator on Shurflo pump based systems: Here is our standard set up:




Charging up the accumulator is only take a matter of seconds, especially the small 22cc one. The think the advantage far outweighes the disadvanages.


I wonder if you do a some test for me as you already have set up the shurflo and power supply, I have been asked to verify if a small nozzle (such as the one you are using) will response to a full scale voltage/current change, ie 0-12VDC or 0-100% chopped 12VDC (PWM). I wonder if you could do a plot of voltage vs flow and current vs flow on the same nozzle.

Please tell me what cam angle are you using on this shurflo pump?
