New to meth/alky
Slowcar,
A bit OT, but maybe not. I was going to pm you this question, but decided to put it in the forums. Maybe we could get some healthy debate going, and leave the vendor bashing out of it..... which I know we could going the pm route, but I'd like some other viewpoints as well.
I was about to scrap my alkycontrol pump type system for the Aquamist, due to it's ability to quickly and positively control alky injection only when you needed it, and not "dribble" after the fact and lead to cylinder wash.
But I noticed that during our dyno day in Jan., you were throwing some healthy flames out the tail pipe when the pull was over, and I was not. I'm struggling to understand where the extra fuel was coming from on your car vs. mine when letting off the gas. Also, a liquid (methanol, ethanol, water) is pretty much non compressable. A lot of people keep posting that the lines have to de-pressurize, and all that extra alky goes into the intake. But the alky lines are ss braided teflon lines, just like brake lines, who's claim to fame is they don't expand like the stock rubber ones do. If your injection nozzle is mounted at a high point compared to the lines (like mine is), the only extra alky you get is from the pump going from full speed to no speed. Not sure how quick that is, but it was quick enough to not cause my car to not throw flames after a pull.
I'd appreciate your input on this.

I just got back from Plano, will go have dinner and then do a few pulls and post a Zeitronix log of rpm , boost and AFR.
The de-pressurising can come in 2 forms:
-the line "balloning" AND
-the inertia of the massive motor spinning, and slowing to a stop
by putting a solenoid inline - open when pump is active, close when pump is not receiving anymore signal will stop the run-on from de-pressurization
SlowCar -- Should all Alk / Meth. setups have this inline solenoid ( I guess it can always be added) and is there more risk of pressure loss due to one more element between the pump and the nozzle? Thanks
A high Cv solenoid will not impede any flow restriction when open.
a solenoid valve is a must to completely stop the flow of injectant and also prevent suction under vacuum
