pumpngo New Member 24 Member For: 9y 11m 16d Posted 20/04/18 06:33 PM Share Posted 20/04/18 06:33 PM I'm water injecting my xr6 and I'm concerned that the Tmap is in the manifold , and will have water mist going over it . Is it anything to be concerned about ?. When injecting just water do you normally start with half the amount shown on water meth nozzle calculators ?.

pumpngo New Member 24 Member For: 9y 11m 16d Posted 21/04/18 11:31 PM Author Share Posted 21/04/18 11:31 PM Can I get someone that runs water injection with standard Tmap just say they run with no problems. I have the manifold off and if I'm going to move it now is a good time Link to comment Share on other sites More sharing options...

But if you want to be 100% sure, give your tuner a call as they'll be the one dealing with the problem if there is one Link to comment Share on other sites More sharing options...
pumpngo New Member 24 Member For: 9y 11m 16d Posted 22/04/18 10:42 AM Author Share Posted 22/04/18 10:42 AM Thanks , I've searched and found nothing as well, but thought maybe I'm just asking the wrong questions. I'll be tuning it myself. That's why I asked the question, also it's a homemade water system . I did find some comments on how un necessary water injection is, seems some people prefer to use e85 or rich mixtures or retarded timing in preference , but I just see all options as equally valid and personal preference. Plus trial and personal error, rather than just going with watever is concidered as main stream. Not that I don't read lots about other peoples experiences. I actually like the idea of using a very old school method using piggybacked injectors switched on by a hobbs switch to inject e85 in a metered way. Main system normal 91 fuel and a tank of e85 with it's own pump running the piggy back injectors. Problem is in my area e85 is sold only one station, so I'm opting for water only system.

I suppose if it's ok for devils own to recommend it, it's good enough for me. Link to comment Share on other sites More sharing options...

norrs Donating Members 448 Member For: 17y 4m 8d Gender: Male Location: Darwin Posted 03/11/18 09:42 AM Share Posted 03/11/18 09:42 AM Regarding my thread linked above. I still run water meth everyday on the aquamist system and its never missed a beat in all these years even though I'm 22PSI at 500 HPAW everyday. I did upgrade the system two years ago to put in larger jets in and I soldered a part of the motherboard to allow it to overclock the standard Max injection. I had to do this when I upgraded my injectors and turbo, and I was maxing out the Meth system. 1 Link to comment Share on other sites More sharing options...
