Topic: budget water injection for lemony boosted vehicles?
just a random thought on boosted vehicles in lemons.
The absolute cheapest way to boost "safely" is to substitute water injection instead of an intercooler. it also allows cheaper suck-through turbo setups that can't have an intercooler.
the next problem with this idea of course is you need to control the water flow. so what would happen if you added a 2nd much smaller carburetor to the system that was fed water instead of fuel? you'd have to fatten the mixture a bit on the fuel carb and you could control it's throttle plate with a low pressure wastegate actuator setup to fight a spring so it comes on progressively.
to prevent rust you'd have to switch it to gasoline before shutting down for the evening, but that's not that big of a deal, i think you'd just need a shut-off valve for the water let the carb suck dry, fill bowl with gasoline and let it suck dry again. refill bowl with gasoline and you're good for the evening.
