I need to be schooled on water/meth injection on a n/a 460 with 2x4's on t/r. Is it doable ? How much comp. can one get away with on about 94 octane? Brand of kit ? How much? Is it a feasible way to safely (detonation) run say 13ish :1 c/r on pump gas ?
I don't have that exact experience and I am certainly no expert,...but I run pump gas in my turbo and I figure the dynamic compression gets up to 18:1 in its current state of tune. Also, Something I learned while tuning was to limit the amount of water/meth I use to only bring the AFR down by three quarter to a half a point from where it runs on gas alone. Too much and you lose power without knowing your full potential and use a lot more water/meth than you need to. Play with it enough you will find a sweet spot where the engine runs really nice. I use Banks Double Shot. I like the gauge/controller and it also egt if you like that tool
