Pure Distilled Water

Thanks for another great reply. Your posts are the main reason I think pure water is better or good enough (like in wrc)

So do you mean that if my current fuel/spark system allows me to run around 12.5a/r water will be more beneficial?

I've tried 12-12.5 before, but got a lot of timing pull, I now run 11.5 it has little less timing pull, . So in this scenario is pure water more benificiary?

Thank you for replying.

Conventional being higher than 12 afr?

So basically even if I can ignite it and have higher than normal AFRs, w/m will still produce more HP vs pure water? Or would they have the same effect?

I ask because I've seen two 1.8t produce power (without meth or water) on 93pump on a 1.8t @ around 13afr. Not sure how much timing pull.

Dyno @ 13afr/93pump/25psi - Check the AFR
