Has anyone doen that water injection treatment on rotaryresurection.com. I ask because I was considering doing it, but I'm a bit worried about it, so I was hoping someone could share their experience and if they noticed any results after doing this treatment. Thanks.

 

It's commonly done to free up and remove carbon buildup from the internals and combustion chamber. The procedure won't hurt the rotary engine if the engine is basically sound anyway. It probably won't help and engine thats on its last leg.

I've done it with water and I've done it with Sea Foam. Probably something you should consider doing maybe once a year. But if you don't granny drive the car, you probably don't have much carbon build up anyway.

I've noticed a smoother idle and a smoother pull through the power band, when I've done it. It makes clouds of dense smoke which please the neighbors and thats always fun.

Bottom line? Its a personal choice
