For those people not requiring an EPA or CARB certified CNG system, there are several options available, some of which were mentioned earlier. CNG ESIP Parts Packages are available at Raso Enterprises. Assembling the components will NOT result in an EPA-certified system so the Packages are only recommended for off-road applications. As a limited-time promotion, 4 & 6 cylinder packages are specially priced.
The above prices include the basic component package, a hose & clamp package, and a vapor filter(s). An interface cableis also required to connect to a laptop computer for configuration.
No installation support is included with the ESIP parts package and the ESIP package is NOT recommended for the DIYer. However, CNG conversion shops (like Bob Mann's CNG VW Shop) could easily help to ensure that the parts are correctly installed so that the installation meets NFPA 52 and that the package is correctly configured for low emissions and high fuel economy.
Hello After a number of years of building CNG VW turbo setups. I have found the set up too work great and
at 60 cents a GAL of CNG at my oun home filling station to be the best deal in the USA. But I never got the state or the USA to help me and this site too. I find ever one just go,s to the gasoline pumps and bites there lip and takes it were the sun do,s not sh+++.
With that said I have found it is best to just do the convertion to your car or truck get a home filler and save money and your part of the planet.
I have moved on to build a new wind mill called the Tree Top Wind Mill it bolts to the top of trees or your home it is a
Vertical Axil Wind Turbine 4 feet high 3 feet wide wieghs 55 LB and makes well over 500 watts at low speed.

Bob does have a nice CNG conversion. Unfortunately, the more fuel-efficient the vehicle, the harder it is to get a reasonably quick payback on the conversion. If there isn't a public CNG station nearby (there are 2 in the Boston area), installing a VRA (like BRC FuelMaker's Phill) adds a few thousand to the price but saves on the fuel price (less O&M costs). Bob could explain this much better than I could.
I think the biggest problem is sticker shock. A lot of people have no problem with spending a couple hundred dollars on a cold air system (for example) with a marginal return on improved fuel economy yet will balk with spending a few thousand on a proper CNG system that has a realistic payback. Going back to Bob's point about gas pumps and sunshine, I think another way to say it is that a poor man can spend $50 twenty times but can't spend $500 once.
Other problems are the scarcity of public CNG stations and the often high relative cost of CNG when its available. Clean Energy's apparent policy of pricing CNG about $0.50/GGE less than the going price of gasoline makes the return on a CNG conversion and the premium on an OEM CNG vehicle often marginal at best.
I've also heard of concerns with reduced power and with limited driving range. If you're a commuter, low fuel costs are more important than 1/4 times. If you don't mind having to fill up more often (like every night when you come home), the important thing is that you have enough CNG for a round trip.
Hello Frank thanks for the nice words. I have found the VW 1.8 Turbo the best of both worlds I have gotten 40 MPG on CNG a few times and 300 miles to the tank. To drive one of my CNG Turbo cars is something. There is now CNG car out there that can out power one of mine.
But as I have said before I never realy made and money doing the convertion to spoty.
I did build a 500 HP CNG bi-Fuel 2001 VW Beetle street racer for my self I still have it. It is warming up here today I plan
on shovling it out of the snow and drive it.
For cheap tanks just go hear they are refurbished. Plus they sell Brand neew tanks as well.
This is a good site to check out.
Thanks Rick, that is valuable information.
It gives us a rough estimate for costs and that is a good place to start.
