Can any one help?2004 wrx ppp pack fitted just about to fit water injection.running meth and water i need to know injector size and because of ppp remap whats the injector durtion 85%?

 

for any help on this I would go on to the NASIOC site. Aquamist run a thread over there, go into Forums, Technical and find Water/meth injection, Nitrous, intercooling thread. I think the chap Richard who answers questions is based in the UK.

Thanks trev ive allready chatted to richard thats why i need to know how big my injectors are and dutie cylce so i can work out my methanol injector size to get mixture correct .

 

I've always known the blobeye wrx blue injectors as 380cc, some say they're rated 420cc. Not sure about the duty cycle, you would expect it to be below 85% on the ppp but I would pm one of the mapping chaps on here, JGM is always helpfull or Bob Rawle who has run W/M injection, again very helpfull.
When I installed my W/M I'd upgraded to pinks 550's and ran a 0.8mm injection nozzle.

@ 30,000 miles.

I run Aquamist 50/50 water and meth injection on my newage WRX..........but with a few more mods than you have.

Sorry to be a pain but are you fitting Aquamist / meth injection to a TD04 turbo?

Hi yes tdo4 turbo ppp pack and sti intercooler aquamist system with 50/50mix

 

Hi at the risk of sounding negative I would suggest the money spent on fitting and mapping the aquamist would not result in a huge gain given the small turbo.

Perhaps going for a larger turbo (TD05, VF34, VF35 etc) plus supporting mods might give you a lot more bang for your buck..........

Thanks for advise mate had WI kit from other car and fitting etc will do my self so no cost really but yes am thinking of td05 at sum point

 

tbh i wouldn't bother water injection at that level of tune is pretty pointless.

 

Don't forget that even if you fit it for free then you will still need to map it......
