Not another HHO thread !

This is not about water injection, and DOES NOT have A-B testing, just the usual magical claims.

Oh I thought it would be able a chemical intercooler.

My Insight runs almost a 11 to 1 compression on pump gas and I have seen it hold higher timing on midgrade, difficult to measure mpg improvements, but it seemed more decided in the cvt ratio selected for a giving load. I thought about trying one to see is it can pull more timing what mpg would be.
