cheap water pumps for water injection?
 

I'm having a tough time finding cheap water pumps for the water injection set up I'm trying to put together for my turbo setup. I can't find a pump that flows what I need for less than 100. I need a water pump that can do 40psi or more at about 9.5 gph for cheap. I'll be sure to do a fancy write up on my water injection setup when I'm done.

you may have already seen this, but its the best thing i could find

Kyle, wasn't there a few people on here that have done cheap water injections? Have you pm'd them?

Re:cheap water pumps for water injection?
 

I was gonna post this....
awsome little set-up...

Re:cheap water pumps for water injection?
 

My water injection kit that my friend used on his buick GN uses a ford truck inline fuel pump. He said he bought it for $40....

Re:cheap water pumps for water injection?
 

From northern tool, $60.00 SHURflo #2687 60psi 1.4GPM

Its the one I'm using.

Re:cheap water pumps for water injection?
 

Looks like the best deal !!

Re:cheap water pumps for water injection?
 

where are you planning on putting the nozzle?

Re:cheap water pumps for water injection?
 

I already checked out the dawes website, thanks. I searched on northern tool and I didn't find that part number, hopefully I can find it if I look again.

you probably couldn't use the stock honda fuel pump because the water would rust it shut.

before the tb after the bov.

Re:cheap water pumps for water injection?
 

LOL! i was just going to say go steal one out of a camper.

Re:cheap water pumps for water injection?
 

I bought one model down from the one pictured above, that fucker is pretty big, I need to find a place to mount it, ----.

Re:cheap water pumps for water injection?
 

isn't water injection were you're spraying the intercooler with water?

not to be a noob on this issue but i thought that was what it was?

or something else?

Re:cheap water pumps for water injection?
 

water injection is where you inject water into the intake air so it cools it down like a mofo and make your engine go faster with more type-r speed.

Re:cheap water pumps for water injection?
 

but isn't that a bad thing to have water going into the motor?

Re:cheap water pumps for water injection?
 

You just tap your engines water pump and have it cool the inside of the cylinder instead of the outside of it, that way your car runs much cooler in the summer !!!

BTW Its not a tight car, unless its a Type RR

Re:cheap water pumps for water injection?
 

Water injection is a cheap excuse for cutting a corner somewhere else. :P

Re:cheap water pumps for water injection?
 

Or a good excuse not to pay $7 per gallon for race gas...

Re:cheap water pumps for water injection?
 

Water injection is a good charge coolant but you mustn't use too much or you'll lose power. It's not a magic octane booster and has nothing to do with gas octane directly.
I'm thinking about putting water injection for 2 reasons:
Help keep charge temps down on the street as I have a water to air intercooler which soaks up in hard driving.
Keep the engine clean, I have a variable nozzle turbocharger which doesn't like carbon, and excessive carbon buildup can seize the control nozzles.

Re:cheap water pumps for water injection?
 

Is is a magic octane booster if you mix alchohol in with the water ;) You also won't loose much power than way...

Re:cheap water pumps for water injection?
 

ay si, somebody has max boost in their bathroom in front of the toilet.

Re:cheap water pumps for water injection?
 

i was thinking of spraying my intercooler with water.. what kind of fan nozzle are you using?

Re:cheap water pumps for water injection?
 

exactly. If you had an intercooler than ran at 100% efficiency than water injection would be worthless. But since none of use usually have this kind of intercooler water injection is a practical solution to a common problem.

Re:cheap water pumps for water injection?
 

why dont you just use your windshield washer sprayers. hook them up so that they can spray the intercooler and you have a tank already there. thats what the new wrx sti uses. alot easier then making something from scratch

Re:cheap water pumps for water injection?
 

mahcivic, I'm not spraying the intercooler, I don't have an intercooler.

corky bell's downfall is his quest for the perfect intercooler and saying anything that would be useful if the intercooler was not at top efficieny is trash.

Re:cheap water pumps for water injection?
 

So even if your using a regular old tyrus or custom coach with good tuning... what was the problem again??? ???

Sounds like another thing that you would ---- something up with. Not too little water of course, but too much. So many of our cars have run without water injection, so why would you need to?

Re:cheap water pumps for water injection?
 

fmic: $300

water injction kit: nozzle $6, pump $50, activator free (using chips from national.com), lines $5 (estimate) total: $61

Re:cheap water pumps for water injection?
 

Cost of completely being a cheap ass = your motor.

Sounds like bad accounting on your part. :D

Re:cheap water pumps for water injection?
 

Maybe you should go check out the 100's of 400+ hp supras, stealths, dsms, BUICKs, and other very successful alocy/water injection users...

Its also super reliable.

Re:cheap water pumps for water injection?
 

uh...have you checked ebay? i got a front mount 36"x5"x3"
$245. shipped. that was 3 months ago. i hear the price is lower now. don't complicate yourself, or get a dsm side mount ic. that water injection has to be precise or hello hydro lock! good bye pistons & rods!. good luck

Re:cheap water pumps for water injection?
 

Corky's book has nice pictures in it but his theories aren't as solid.

Re:cheap water pumps for water injection?
 

Water injection is such a shitty device and harmful to your motor that they come standard on the EVO's and STI's...

Re:cheap water pumps for water injection?
 

And if low compression is so bad, why do EVOs and STis come with 8:1 compression standard :)

Re:cheap water pumps for water injection?
 

Reliablilty. They can't be producing high compression with high boost motors and still have warranty when higher compression has less room for error and has a higher likelihood of something going wrong and a warranty has to pay for it. cars are mostly designed by accountants, not engineers.



Give it up, your not going to convice me that low compression is the way to go. Many people use low compression sucessfully but its something that I just don't like and think is a good thing :-\

Re:cheap water pumps for water injection?
 

my motor is already fucked, but I will be using this ---- on my LS block, it's reliable and lots of people have had success with it.

I ran the numbers about 12 or 45 times and I still come up with $61 being less than $245, damn.

Re:cheap water pumps for water injection?
 

Ha ha, even whitey quoted Corky. lol.

I'm sure theres a reason beyond an intercooler that those 400 hp cars run that ----. I'm sure it's not because their cheap asses. On the other hand, how many successfull HMT turbo kits have passed through here without water injection? It's another complication to tune that ---- right, and with it in Kyle's hands, he's bound to ---- everything up. <-- I'll come back and quote myself when he does it. ;)

Re:cheap water pumps for water injection?
 

I will admit that water/alcoy injection is just one more thing to figure when tuning, which is why my friend sold me the alcoy injection kit off his GN for $75...

He said I've got:
93oct + alcoy
100oct+ alcoy
straight 93oct.
straight 100oct.
straight race gas

All of which have different boost and timing settings...

He got a fel-pro ( speed-pro ) stand-alone and basiclly gave me the sweet alcoy injection kit ( which he used for many 11sec time slips over a 2.5 year time ).

Gm was looking at using water injection on the GN as an aid to help IC-ing, but found that after ONLY 200K miles the cylinder walls started to "wash out"... There is even a "dummy light" on all buick GNs that say " power injection", that was meant for the water injection system that never made it to production...

You guys are killing me with the constent meantion of IC sprayers, which are not water/alcoy injection...

I have the water sprayers on my civic, and if I ever loose my mind and try to run some 12's on my stock Z6 block, you'd better bet plans would include water injection, AND maybe a really small shot of nitrous...

Re:cheap water pumps for water injection?
 

blah, I ran 17psi on 91 octane, with 3 degrees retard. No need for that ----. I think you guys are trying to make this more complicated than it is.
I doubt kyle is even planning on running 12psi, so I doubt he'll need anything other than the highest octane available and the shittiest intercooler he can find.


One time I ran my turbo with oil only, and I left the water cooling unhooked :o, even though fords came with the water lines hooked up. :P

Re:cheap water pumps for water injection?
 

I definitely take offense to that. Corky Bell didn't invent that saying much like he's not the all mighty God of turbocharging. and also Stupidmode, you ran 17psi with 91 and 3 degree retard, since you never tried water injection you might have been able to run a 1 degree retard. But you'll never know becuase your stubborness is more retarted that your timing :P



Also, many kits passed through here with only FMU's, many kits passed through here without intercoolers, ect. Just becuase its not known to most people doesn't mean its not a good thing. Water injection is VERY popular with superchargers that can't run intercoolers

Re:cheap water pumps for water injection?
 

Ok, on my next project I'm gonna run A/C injection. It will cool the intook charge just fine. Then on the project after that, I'm gonna put my charge pipes in the freezer every night and then install them ever morning so I don't have to run an intercooler. :o

Wow, this is fun. I wonder if we can think of a way to replace the $80 turbo, cause that's expensive too. Maybe we can use a stolen hairdryer from a salon to turbo our cars.

(am I done now?) :D

Hmmm, I wonder if it would be cheaper to buy an intercom speaker and a microphone instead of a blow off valve. :( Depending on the volume you could achieve, the microphone/speaker combo might be able to make more noise than the bov for a couple less dollars. :)
