I never found any real details on it either.
As far as nothing improving mileage????
I did work in the early 80's to improve the mileage of my 78 subaru coupe.
In the end I had changed the mileage from 40mpg to 60. Of course vehicles were very different in 78 than they are today.
At the moment I am almost brain dead after very little sleep...so I might not be making much sence right now.
hmm some of what I did. I switched to syn oil. I made my own water injection system tapped into a vacuum line. Because of this I was able to advance the timing, without any problems. I also slightly increased the sparkplug gap. I preheated the fuel by inserting a section of copper tubing into my fuel line and wrapping it around a pice of tubing inserted into my radiator house. [ that might have been stupid] As it was it took some work to get that part just right..so that I was not vaporizing it too much..and with the fuel changing seasonally..making it harder. but I did get to a point it helped.
I did install a computer that measured my milage as I drove. I did make a slightly freer exhaust. I also had larger wheels made. hmm I think from the 13" to 15" which meant I had to use the computer to read my speed and distance after that.
This car was designed for leaded gas..I mixed regular leaded, with regular unleaded. hmm I won't remember the proper terminology...
the leaded gas used the "lead" for it's octane.. and the unleaded used something else. These can be dilluted without affecting the octaine numbers as much. The end result was I had a fuel with higher octaine than I started with. This also helped with the advanced timing and increased spark plug gap.
back at the time I got local newspaper and tv coverage..the reporters also checked with governing agencies..as far as the smog devices and such... [they did not want to get me in trouble in reporting about what i was doing... they endorsed it] What I was doing should have reduced emissions.
There was not really anything "new" I was doing. I just read a lot..combined ideas.. and did a lot of tinkering.
I did do a test fleet for someone and was able to fairly easily increase a vehicle's milage by 20%. [this was much less involved than what I did to mine]
If I had had more money..and a different vehicle. [this was our one and only car] I would have liked to have tried more.
