Pot of hp stew
that'* a good one.
I bypassed all the electronics and wired direct to the pump for testing only.
It is based on MAF not boost.....somewhat related....read up on the SnowPerformance.net site.
"Snow Performance has developed a new Stage-2 Boost Cooler™ water/methanol injection system for ’96 + GM mass air flow equipped vehicles that uses a new Digital Variable Controller that varies the quantity injected with the engines mass air flow. Because the correct amount is injected at all RPM/engine loads, power and drivability is much improved over the typical on-off systems. The Variable Controller features adjustments for onset mass air flow level and full quantity mass air flow level so the injection curve can be maximized for each application and can be mounted under hood or on the dash for adjustments while driving. The Digital Controller reads the frequency output from the GM MAF sensor to the PCM and varies the injection quantity accordingly.
Other Stage-2 features include a 150psi pump and specially designed two-chamber nozzles for even better cooling/atomization."
I redrilled using a 23/64" bit and it was just enough. Any bigger and it would have been too much.
It'* perfect now. The spray pattern is much improved with no dripping. Very good advice Bill, thanks.
Time to button it up and get rid of the Pot.
Now back to wiring....
