Wide Ratio O2

[Bernie Jacobsen]

Does anyone know if water injection systems are still available (I remember
them from the 70's and early 80's, but haven't seen them since)?

Can you still buy systems? parts? Or is 'home brew' the only option.

I'm interested in it for a '85 Motorhome with a 454.  I would like to
advance the timing for better fuel mileage.
