Subaru knows a thing or two about building wagons that can go off-road. Their latest release in this market is ...
Has anybody done or contemplated doing a CNG conversion?
My thoughts would be on a DD or car hauler...
I've thought about it, common in the rock crawling world, you can run dual-fuel by simply putting the CNG carb in the intake ahead of the gasoline carb/efi system and cutting the gasoline.
We're doing them now. The installation isn't cheap but the people who've done it find that the conversion pays for itself in a year or so. Assuming you spend $20k a year on gasoline, anyway. Given the size of the tank required for any kind of meaninglul range, I'd only do it to a pickup. Figure a tank that is 20 gallons-equivalent will take up the width of the bed, and the diameter will be almost the height of the bed. Steel or spun-carbon tanks are available, with the expected tradeoffs of weight vs. expense.
A gallon-equivalent of CNG is about $.80-2.00 depending on if you buy it from a filling station or have a home fill station.
The new systems are neat. They interface with the PCM in such a way that the computer doesn't know that it's firing the wrong injectors. It's kind of like a piggyback but in reverse.
