another water injection Q
let me know if you think this setup would work
use stock fuel pump as water pump
run hose from fuel pump to nitrous fuel seloniod (and i could use a fuel filter also) run line from fuel seliniod to dry nitrous nozzle
and this would be on a WOT switch
any reason why it wouldnt work i figure ive got everything needed except for the dry nitrous nozzle which would only be 20$ and i could use readily avalible NOS jets to tune it (i have access to alot of NOS jets)
ive used the stock fuel pump to pump water in the kichen sink to flow test injectors so i know that wont be a problem
i also thought about using a fuel injector instead of the nitrous stuff but i think the nitrous will make it easier to get the right amount of water tuned

Sounds interesting.
You could even get a SMT6 or similar piggyback ECU to drive/cycle the solenoid per load and/or RPM like some of the more expensive WI units, so you could tune the amount of water when/where you need it.

yeah the only thing that jumps out is getting the amount injected right. also will this mist properly without 800+psi nitrous pressure? also, would the pump/solenoid hold up to meth or are you planning water only?

i am proboly going to add about 30% denatured alcohol since its cheap and redily avalible to keep it from freezing and also i assume with adding this alcohol it will slightly change my A/F ratio
i agree with the dry nozzle not adimizing properly so i think im going to run a 200cc injector instead i figure that should adimize fine
im have a ford fuel rail that i cut up so only one 19lb/200cc injector and the stock presure regulator are left on and i will just hook it up like that
ive looked at some other systems and found that one states this "Easy install Injector nozzle - 315cc/min included. Good for 250-400HP applications." so for my current NA aplication of aroung 220hp a 200cc injector would be fine
it also states this "The experts recommend that the most efficient percentage of water to fuel ratio is 15-25% regardless of droplet size." so once again the 200cc injector should be close but i might get an rpm switch so the injection doesnt come on before say 4000rpms
plus i can always upgrade the injector when i go boosted or get a ajustable regulator "ford adjustable regulators are CHEAP" or ad an adjustable pressure sensor as well to open a second injector at X or XXpsi
one more thing i assume this should be mounted after the MAF
and was wondering if this should be turned off when im spray nitrous i know there was a discution about that but i dont remeber the conclusion

WI decreases the chance of detonation by slowing the flame propagation inside the combustion chamber, whereas N20 speeds flame propagation. Although, it does cool the charge which slows propagation some, but not enough.

I would be worried about the fuel pump eventually rusting in critical places and failing when you need it. You ought to do a test. Submerge the pump in water for several weeks and see if it still runs. Or if it does run, see if any rusty water comes out of it.
#11
well i figure since the system will be used every time i go WOT the pump will alway be "self cleaning" itself so rust will never have a chance to form but i could be wrong
im going to be going to the dyno again now that ive got my ajustable fuel regulator and an assorment of NOS jet to tune every thing better and would like to see if i see any gains with this setup NA and if it helps or hurts with nitrous
i also really like the idea of how the system is supose to steem clean the intake manifold and combustion chambers

its funny you brought this back up i have made some progress with it althought still dont have it functioning

i have a ford 19lb (roughly 200cc) injector and a rail i hacked up with the stock regulator im going to hook it up to the stock fuel pump and have it on a WOT switch for now i just have to mount the pump and make some kind of container to hold the juice
and althought the spearco water injection as well as some other systems are very affordable im am CHEAP and i figure i can make a product perform just as well for in my case FREE i will do it plus its a fun learning experience

Subs. Sounds good. You read the SCC article with the SER turbo with Aquamist? Is there some rough estimate you are using to determine pressure and injector size? I know in that article, there was a mention of jet sizing etc..
#17
ive read your suppose to use around 15-20% water/acohol to the amount of fuel your injecting so ill be close but probobly should use a 14lb injector while im still N/A.
regardless its not going to be enough water to hydrolock the motor or be dangerous
