I'm adding a flow guage to my WI system.I spent the last few days educating myself on flow measurement--you can spend 2 thousand dollars or 1 hundred.I have found what seems to be a good setup(yes it can handle methanol)I will let y'all know if it works out but it will be the best way to tune using actual flow/preassure data.one guage even shows average use for the past 30 minutes.as well as the amount of time you have before you need to refill if you have a fluid level sender in the tank.

a couple of links to a good meter wich there are many and education on types of flow measurement.I dont know why no-one offers a flow meter with thier WI system--it is also a good way to see if you have a clogged/restricted nozzle :shock:
