LPG blowing up air boxes theory!.

My experience with LPG is the same, blew the airbox to pieces after dodgy leads crossfired. Have since replaced with eagle 9.5mm leads and fresh plugs. According to LPG pros, the ignition system needs to be tip top on LPG. My system starts automatically on fuel I thinkl, 'cause I can hear the full pump running when switched to LPG and have never had backfire on start up, but then I don't touch the gas peddle. A mates blew to pieces in the middle of the state forest after his son went to move the truck, not happy. Thankfully I've not had a backfire since upgrading ignition. Bottom line is the LPG must go in favour of a 150l fuel tank.

I have however had a similar problem with ignition leads which I corrected by installing high performance low resistance leads (1000 ohm from memory).

Installing low resistance leads in your setup would not go towards supporting your theory of resistance causing the release of unused energy however so it may not be a path you'd choose to take.

Best of luck with your research & keep us posted on what you find.

Thanks for your input.
I guess I miss-led a little, quote myself.
"I put it down to resistance in cap/rotor and std type spark plugs".
I meant this part of thread/post with the notion of it not working together properly, if ya follow.

I cant remember what the Bosch leads were resistance wise,only they were LPG suitable, it was 2 yrs ago now.

I was originally trying to hi light the idea of wayward spark causing ign problems, but thought I'd throw my tune in for consideration also.
All good, anything on the table to improve power and reliabilty.
cheers
