i never hear bout turbo on cng....buh it may be possible with all the correct parts and procedures of carb turboing.......
may be ah bit trickee to tune.....
BTW i have ah CNG kit FS if yuh intrested...bolt on for L28.....

Nice try DROPPA I never said it was a L28!!
anyway people, I just bought a C32 Laurel with a L24 original Carb and a 70Lb CNG system, I like the fact that it costs about $6 or less to get into POS and back, and that I can switch to GAS when I need the power, But I wanted to know if I put a turbo on the L24 if it is possible with the CNG kit.

c.n.g is real high compression....dunno how the turbo gonna respond to dat?
with normal n/a engines the engine does be bawlin like a beyotch and reachin all kinda rpm before the gear change...

when you say CNG is high compression what do you mean, The gas itself is under high compression, or it needs a high compression engine to work? in which case the later would be wrong as it runs on an unmodified L24... right?

he means CNG is under a High Pressure......
But CNG and turbo will not work....tried and tested and failed.....when the Boost kickin, the car just sputterd and could not go....the gas is too weak for boost.....
Even the Super gas is not good enough for turbo....it will cause pinging/knocking

Ok here is a possible solution then, can I use a boost controller to shut down the turbine when I switch to CNG?? and then when I switch to petrol it conmes back online?, WAGONRUNNER, I know there are systems that currently in use out there, but I am looking at more homegrown solutions, thanks, and keep it coming fellas

i was studyin dat...with teh boost controller u cant turn down boost in dat sense
if your turbo is 5 psi stock u can`t drop it to 3 psi.. with the boost controller u can raise boost and bring it back to stock.. so if it not workin at 5psi ..forget it
seems like a lot of expense....the only benefit would be better mileage
is there a way?
maybe u custom fabricate two intakes and exhausts, one n/a working with cng and one boosted working with gas. when u flick d switch one closes off and the other opens
whey de engineers dem
lol

How will CNG cause pinging? The Octane Rating is extremely high!
