Hey guys,

Looking to set up water injection setup on my Volvo for decrease in air temperature and less carbon. I run up to 1.25 bar which seems fine on 93 octane if it is ~70 degrees out. I am hoping with water injection the management system will be happy with 18psi. I do not run a boost controller to force it to run 18 because I want the management system to be able to protect itself.

Will I be fine with injecting just water or do I need alcohol also? This is not a dragster I use it for occasional autocross but mostly a street car. Also any problems with spearco? Again like I said this is not a race vehicle
