Has any one here built one for a car.

not one, dozens . Be very careful if you don`t understand air fuel ratio heat pressure and vaccum. I reccomend you study up on all these as gasoline reacts different under all these conditions but they will and do work. I built my first in 1977 ran on a 1969 chev 6cyl then 1985 chev 4x4 and put 265,000 miles never changed oil only filters. Vaccum and pressures are key components as the heat will be different under these conditions. Vaporizers will work on carbs but my reformers work great on fuel injection multiport. Good luck but be very careful as I have blown up 2 trucks until I learned what was going on and how to control it but now Iunderstand the whole concept and its totally as safe as a carb now. safety Dan gadgetman mo.

Ok, I'm curious?
What is your reformer and what kind of gains do you get with it??

Thanks,
Ron

this is a fuel reformer it breaks the fuel molecules.down to easier to burn and more powerful molecules. As for the mpg from double to tripple depending on compression of engine and the way you drive. I will be demonstrating a 3 gen model this weekend the 5 gen is showing upto triple mpg on an avg. 1,2,and3 gen are doing double at least. There are a couple of the gadgetmen doing some testing for me and so far they are amazed it is so easy. Fuel trims running neg 10 to neg 25.long and short.This is not a vapor carb as I built in my earlier years this is safe and fool proof.The ecu works for me not against me. Anyone that wants to see on my 97 ford truck this weekend Ill be meeting Aron and Ron in Nebraska on his tour Sat.all day. Come join us and spread the groove as we all know alittle groove makes a big difference.

Dan,
Are you going to stop in Michigan? Are you going to start selling your reformer? It sounds like they work great with the groove.

Dave

No, just nebraska and in the future I`ll sell them at least thats the plan. Yes the groove is definitly an enhancer to the reformer. I`m just trying to get it as small as I can with still the same results. dan gadgetman mo.
