Water-Injection for planned twin-turbo setup?

gussyturbo z

Hey man I have the stillen sc kit with aem meth kit. I have learned that it does not make any power. We had the car on the dyno at uprev we made a pull on the meth and lost 20whp. I don't know how it will work on a turbo setup but on mine it was not a good gain. But it does make some cool fire out the back of the pipes! Good luck man!

Pics or it didnt happen.

Do you still have CATS or are you running with tesp pipes?

I have good video on you tube of it shooting fire out the back but I can't post it here cause we were doing some street runs against an Evo. I'm running the 3" AAM catback with test pipes too.

when i had my stillen supercharger and water/meth kit
i did not get a chance to tune the car for the water meth but i did run it
and i noticed a big change in how hot the stillen intake was
the intake ran way cooler when i was spraying the water/meth

I have the Stillen SC and Aquamist meth injection and my WHP didn't go down any. My tuner said we could add some timing and probably gain some WHP but I told him not to. I just wanted it spraying as much Boost Juice as it could take without costing me power. I'm guessing you are spraying to much because when we turned it up to high mine started dropping WHP.

Yea I think your right man I might be spraying a little too much.

In my experience water or water/meth will not by itself will not add any significant power. While you would expect some due to the cooler combustion the mixture displaces some air/fuel so its about a wash.
Why then use it?
1) Added to a correctly tuned engine with no tuning changes it is the best insurance against detonation.
2) It allows you to increase timing and reduce fuel both of which add power. The down side is that you are then relying on the system to protect the engine so it had better be bullet proof.
