thats just a fogger right? so it just runs on a little CNG, not solely right?
ive heard someone tell me about using LPG or CNG on a diesel before, but running it through the injectors and injection pump. and its ran as a liquid. or was someone just telling me about some hair brained idea they had?

Ya it's a fogger.
I'm injecting it pre turbo. The gas is changed from high pressure to low pressure just before the intake.
It uses a stepper motor/valve to regulate the gas. Uses the crank position sensor and TPS to adjust..
It's a fully programmable system via lap top program.
I would actually like to discuss the kit/ conversion on this board over the TDI board. There is maybe 10 guys over there that aren't conceded and those guys are on this board as well.
I'll post up some pics hang tight.

does it have any sort of limiter? like does it look at the EGts to see when stuff is too hot and it should probably inject less? or is it one of those things you could burn your engine down with if you were not careful?

Gauges will be here this week so I cant answer that just yet.
I wanted to have them installed before I got the kit installed but those damn things are spendy!
It will be limited via programing. And as stated it uses the TPS and crank position sensor to regulate the gas so once it's set up I'll be covered.
It has a fail safe if the TPS and crank sensor dont jive along with leaks. It just turns the system off.
Of course I can turn it off manually as well and the tanks have electric valves and default in the off position as well.

How many years supply of CNG is that?
How long have you had it installed for?

so CNG is better then propane injection? I've heard good and bad about propane, mostly that as a booster NO2 is still better, with less issues with runaway.

Better? Cant say don't have and haven't had propane injection. I believe this kit can be used with either fuel though.
The power it adds is AMAZING for sure and that's why I added it. I should get a considerable fuel savings as well so that is just an added bonus.
I dont see how you could get a runaway with this system as it's fully computer controlled and uses engine sensors to regulate the gas.

propane/CNG works wonders on DI motors, really surprising how well it works.
if only there was something as cheap to put in our little IDI's that had a similar effect...

There is no reason this system couldn't be used in a idi engine, I wouldn't run it on a NA engine but a TD engine sure.
It's compressed with the air so bam would happen...
Regulating it could be fun without electronics though, may have to add a TPS on the IP for the system to read.

I'm pretty excited about this system, REALLY looking forward to having it fully tuned so I can get it tested at the emissions station to see what's coming out the butt.
If I get the chance putting it on the rollers would be nice as well to actually get an accurate measurement on the HP/TQ #'s.

IDI motors do not like the way that CNG/propane burns, it has a tendency to push out prechambers.
