Anyone with a water/methanol injection kit? does it make a difference/gains with a TT Z?

I have been wondering the same thing, could someone explain this for us

most guys using WI kits on this forum are using them for safety and not to get extra power. I know Todd from Builtzmotors is using one.

It helps a lot towards reducing detonation and therefore giving you either a safer tune OR letting you push a more aggressive tune with reduced risk of detonation.. (Gman is correct, most of us let our FI systems/do the work and use the Alky/Water injection for added safety on the tune)

I will let someone with more experience get into the details. Basically you can read up on it here though.

Thanks for the info bambam and gman.

I know that after adding the WI it makes the AFR more rich. do I have to return after installing the WI kit? and which brand is recommended for the Z?

yeah you'd need some tuning involved

you can always just run water by itself, but it's not nearly as effective and can freeze in cold weather which might crack something

From what I am told using water/ meth. injection has most of its gains in the form of being able to advance timing and other tuning parameters more agressively gaining power that way. Have my custom kit installed but have not dynoed since there is 1ft. of snow where I live and car is in storage, but will be getting it tuned with injection in spring.

It's basically like running high octane fuel. The only differences with gas is the ability to prevent detonation. A cooler air charge allows this. What makes it so effective is that a slight misting is all that is needed to drop the combustion chamber heat, raise cylinder pressure (water can't be compressed only air) and prevent the onset of detonation throught the cooling effect water has. With a proper mix you can run more timing and boost. It's dirt cheap race fuel...the methanol mix is even better

i am running snow performances methanol injection....my tuner said its the best kit out there in his opinion ... snowperformance.net .....even if you dont run more timing but want to lean the car out a bit more its almost a bit of a safeguard from detonation and hurting your motor...methanol is in windshield wiper fluid/heat!! u could use this but they supply premixed stuff that u can clean ur windshield with also(by using your resevior for holding it) ...either way always get that car tuned!! too many blown motors on untuned vehicles. ....frown....shakes head.....walks away .....

i run 50/50 mix . and by just leaning the a/f back to where it was [ before w/m injection ] i gain 40 whp. my stock timing at wot would advance to 26 degree's . after the w/m kit was installed . the stock timing advanced to 30 degree . i think the stock ecu went to its agressive map when i added the w/m injection .

I also run a 50-50 mix. My car is not tuned for it, I use it as a safety margin. I noticed an average drop of 50F in my EGTs with the methanol/water injection. I'm using a CoolingMist kit. I'm also using the winsheild washer reservoir for it, works great.

Hmmm... Does it ever get cold enough in Dubai to freeze? I thought it was very hot there almost all the time: 100 degrees+ daytime highs during the hottest time of the year.

yeah running some methanol mixed with the water is usually best thing anyway

it evaporates faster to help cooling and then there's the whole higher octane thing on top of preventing the water from freezing solid in the cold

Sean

he might see 34, but I don't think he will get a bottle of water to freeze outside ever

You might give Sharif a call. He installed a Spearco Water Injection System on a customers car and did before and after dynos. With no tuning just installing the Spearco WIS kit he noted ZERO loss in HP but the AFR went over 1 point richer.

that exactly what I found also , got 1 point or more richer .

Madelinot

iTrader: (1)

I noticed that too, but more like 0.5-0.7. My EGTs went down too

Mia, what a coincidence, I was just starting to research that exact setup.... hum...
Hey I thought Turbonetics sold/rebranded this kit? ANy idea where I can get more information on it?

so i can install a w/meth kit to a tn st kit and it should be ok, correct? i ask because the tn kit i have runs w/the re-flashed ecu and really there's nothing to adjust........i may have asked this before, but forgot, thanks
