na/ water injection, still unsure.
Thursday, August 17, 2006 10:24 AM
Well, i sold my gm s/c and i had the cooling mist water injection set up on the car(still on the car). I loved what it did with the s/c.

Now i am in the process of going back to N/A and am really unsure if i should even waste my time hooking it up and just sell the set up..
ALL i would need would be a WOT switch(15$), and a smaller injector(m2- 8$) . and that is it.

i did some research and said it benifits the most from high compression engines. I read though that it helps lower intake temps.
here is what snowperformance.net says:
Naturally aspirated/stock compression:
With naturally aspirated engines with less than 10:1 compression, water/methanol is used typically in warm climates to get the intake temps back down. Benefits include: 10-15 HP increases from air density increases and full timing, Increased gas mileage, and carbon free combustion chambers. Activation is by a throttle switch adjusted for onset engine load. With this application, the nozzle is sized so that no more than 10% of total fuel consumption at peak flywheel HP is injected.

i dont expect to get better gas mileage, dont know where people come up with that.

thoughts?

I have been wanting to do this on my N/a Z. Of course I live in really warm climate, but I think there could be a gain. I think since you have mostly everything you should try it. If you do please let us know. Wish I had a kit to try when I dyno next month.

ya hard to say.

it will cool the air down. I know it cant hurt. Just want some opinions on the subject if i should just run it, or sell it. I think i should give it a try. I threw out my damn M2 injector, dont know what i was thinking. SO i would have to order one, 8$ aint bad, and if i remember right that M2 injector was pretty nasty. And the WOT switch i see for like 12$.

You are right, everything is basically there and in working order. i just need to wire in a WOT switch, and swap injectors and put it in my new intake when i get it. With the s/c i had the stock S tube with the injector in it.

we will see . maybe, it might work great like it did with the s/c. I could be running lean/ getting some knock with all the mods i have on it, and the w/i will help reduce that, thus adding a little HP. who knows..

One thing I have heard about doing it on N/A you need a good alky mix (higher Alky, than water) which will increase Octane (some).

For the cost and trouble, it's worth trying for sure. I'm sure everyone would love to know if it makes a difference, even my car gets hear soaked up here in Canada (fan switch definitely helps).

i thought of a way i can test it . what i did to test the set up b4 would be just to ground the boost switch. So instead of buying a WOT switch, i would ground the boost switch under the hood like i normally did to test it, and at wot in the car flip my switch inside the car. IF it makes a difference i will keep it. if not i will get in touch with my buddy who i first had it sold to(have to wait to see about his car's motor), then e mail you upcoming z24, then QBE, and if that dont go through, on the classifieds it goes..

i will do a run with it on and with out and see what i notice, if anything

thing is the injector(m4) is sorta big for NA and i have the stock air box over the t/b for the time being . . but we will see. hopefully this weekend.


other way i think it could benifit is if i put it right by the cone filter/ end of the intake pipe. i will be running a injen intake here soon, so that way the water /meth keeps that pipe cooler and not get heat soaked..

as with the s/c, with out the w/i that thing was hot to the touch. with the water injection, after alot of hard runs, the s/c was cold . so i think that same concept would work with the intake pipe.

who knows .
