Supercharged slant

Yes I am using water injection. The kit is from bob at the supercharger store as well. Don't have any hp numbers on 15 lbs of boost. At 8 lbs of boost it made 308 rwhp on a chassis dyno and it would run 12.90s 1/4 mile. That was in the duster that is on their website, I haven't had a chance to fine tune it in the dart or get to a track at 15 lbs of boost hoping for low 12s or dip into the elevens we'll see
