Spraying starts at 10psi and always runs a 50/50 mix. Fg turbo with standard gt3540, original stage 2 pw IC kit with turbo side intake, 60lb inj, single 3.5in xforce with cat still in place! About 400rwkw so conservative numbers. Dave the owner of CPV has tuned a few cars with the kits over the years so has no problems with them. 1 Link to comment https://www.fordxr6turbo.com/forum/topic/35425-watermethanol-injection/page/10/#findComment-1480934 Share on other sites More sharing options...

To balance my tune and maintain the desired AFR to make good power, a total of 14% would had to have been trimmed from the factory injection. This isn't an issue but can be a real problem if the water/meth pump fails. This will more than likely result in a blown engine. I wasn't willing to take such a big risk.Benny.

I asked him how far the nozzle was from the TB and got this photo! HahaDoesn't your stage 3 setup have some funky getup that can release boost, timing or whatever in the event of the water/meth pump failing?

Benny Member 1,869 Member For: 21y 9m 15d Gender: Male Location: Newcastle Posted 26/06/14 10:52 AM Share Posted 26/06/14 10:52 AM The Stage 3 kit doesn't have that functionality but I think an additional controller can be purchased as a fail safe. Not sure how it would integrate to our cars though. The difference of the Stage 3 kit is it has an electronic controller and the ability to trigger from boost or injector pulse width or both depending on how you program it.Benny.

My stage 1 kit only has a manually adjustable boost actuator thingy...I'm pretty sure my mates activates at 10psi.

When I was still running pump 98 and a stage 2 pw cooler, with a 375ml jet, intake temps were down in the low 20s degrees celsius. you wont need to pull fuel out. Ive use a 625 or 675ml jet on 98 and the richer afr didn't hurt power at all.If you aren't going to use the water meth as a power added and just a safety (as I was originally as I was learning to tune and didnt want to grenade the stock engine) tune it without the water meth. Hook the meth up and enjoy. Link to comment https://www.fordxr6turbo.com/forum/topic/35425-watermethanol-injection/page/10/#findComment-1481261 Share on other sites More sharing options...

And the afr will be richer? Link to comment https://www.fordxr6turbo.com/forum/topic/35425-watermethanol-injection/page/10/#findComment-1481272 Share on other sites More sharing options...

This AFR resulted in a loss of power right up until the run was aborted at around 4500rpm.Benny.

You wont need to adjust the tune unless it is stupid rich to start.
