Excellent news. Please add some underhood pictures of fuel rails and trunk pictured of tank mounting (how the heck did you get 7gge in that pathetic little trunk opening?)
Came close to doing this with my camaro but instead modified a tahoe and have a suburban in work.
Also, if you or whoever is tuning CNG fuel under boost wants some hints for max HP drop me a line. You are probably already aware that CNG behaves nothing like petrol on power curve, but just in case.
For others in this thread, I've had excellent success with both commercial CNG filling stations and residential (PHIL) garage appliances. CNG (methane) is 98% North America (Canada mostly) and last time I checked the US wasn't planning on invading and occupying our neighbors to the north to gain access to their natural resources.

on my old 5.7L LS1 i had it running on liquid LPG injection (australia) and i was making 250rwkw on 98 octane petrol and 260rwkw on LPG.
It is about 110octane here and obviously freezing cold when it is injected.
when the engine was pulled apart when i sold it i was told that there was very little carbon build up as it had such a nice clean burn all the time from the LPG it helped the enigne to run alot better.

The fuel rails and such are in the pics that he posted in the beginning. The injectors are off to the side on their own rails, and line run from them to the intake manifold. Most Conversions on composite manifolds drill into the manifold itself, much like a direct port nitrous injection.
PHIL, i can say they are very nice units, lol. And for the price of them, they would pay for them selves in a year or two. (especially at the fuel price we are going)
Its alot like geothermal, the upfront cost is a little high, but the added monthly/weekly benefeits are incredible for a DD car. especially knowing you an come home at night and plug your car in and have a full tank in the morning.

There are no underhood pictures yet. That is a vette sans blower 
ECO in canada makes an excellent system for commercial sale onlythat can be installed one of two ways. Cheap and easy, drill holes into the intake manifold one each per cylinder and attach a tube that feeds CNG from a low impedance injector, or better clean way, mount rigid fuel rail with Y adapters at each injector port.
There are companies already making direct injection CNG units. I'm not sure of current status but check out cummings/westport. Initially designed for CNG/diesel mix. These could work very nicely on a DI system.
Model year vehicles 2000 and earlier are grandfathered in for conversion as long as the system is safely installed. 2001 and later must be certified for emissions which is very expensive and tends to kill "legal" projects before they get started.
That being said, many people modify their fuel systems with nitrous and forced induction which are similarly illegal per the EPA. Its your own personal risk aversion.
NGV death and injury are very rare. Every report that I've read implicates substandard CNG system/installation or damaged/past expiration tanks. In other words, properly designed and installed CNG conversions are verysafe. Gray market systems from India or those that are 20 years old and corroded with battery acid are NOT safe(duh).
CNG tanks undergo many tests including ballistics tests. Literally, the tanks are designed to withstand a bullet hit while loaded at 4000 psi. Late model Police Interceptors (Crown vics) carry anywhere from 4 to 5 tanks. These tanks have proven effective through police collision reports at protecting occupants from rear end collisions exceeding 80 mph.

About how much would it cost to convert the average f body? I would be interested in converting my Iroc. This seems like a great fuel for my new supercharged lt1.

looking for any diy info. cost, parts required,etc.
not likely i will take my car to a conversion shop. ive done plenty of fuel system for turbo cars.
just want get idea of what all is involved for a typical cng system, ive found a place that sell cng, in the neighborhood live in. literally down the street.
im interested in converting my car for this, due to this new discovery. i found the place with the locator link in this thread
if its similar to a high end forced induction fuel system. i usually use bosch 040 pumps with 1:1 fpr with required lines,etc. for a basic rising rate fuel system

The Federal code for CNG vehicle is NFPA52. Anything short of following NFPA52 is not only a federal crime, but would likely kill/maim passengers and others within proximity of the vehicle. I strongly support everyone's attempt to use an alternative fuel, but just want to make sure it is safe.
An outstanding source for CNG fuel stations is CNGprices.com it is user updated includes current status and price throughout the US.

So can the average person buy the conversion parts and do this then? If not what is the average cost of converting an f body. I found a local source for cng as well.
Thanks for any info you can provide.

I suspect the OP has backed off this thread because either he or the company he is associated with don't want direct involvement with the DIY public. Perhaps I'm mistaken but we have yet to see any pictures other than a CNG sticker on a Camaro rear bumper cover. Strange thread.

By "average person" if you mean someone with auto/tech/design/fabrication experience, then yes an average person can obtain the components and assemble a system. The industry in general frowns on this because the liability is huge and the return is small. In other words, a company stands to lose its business if someone is injured while only profiting a few hundred dollars from the sale. More likely a company will lose money selling only one component at a time to one individual at a time.

i see. makes sense. i can see how a diy could do stuff incorrect and cause problems. i assume cng is under alot of pressure. and takes many especialized parts. and procedures. for correct install
