Here we go again,will someone tell me why the BA can not be duel fuel as I am sick of the same stuff all the time that the BA petrol motor is not designed for gas and nobody is prepared to say why.Ford also stated that you could not run LPG on XR Falcons or any Ford fitted with VCT or Traction Control.Total crap.Heaps of XR's on LPG and with Traction Control it is just disengaged on LPG.I can not see any reason why the BA can not be duel fuel and Parnell,Fords authorised warrenty agent for LPG is fitting LPG to BA Falcons
The BA dedicated LPG engine has been specifically modified in areas where issues were found during development in order to make it robust and durable, specifically
- harder valves and valve seats to prevent valve recession (these are not fitted to the petrol engine)
- intake air box and air filter changes to prevent/minimise damage in the unlikely case of a backfire
- domed pistons and stronger con-rods
to increase the compression ratio and prevent damage from a backfire
Aftermarket conversions do not do the internal modifications to the engines. Of course you could fit LPG, but you are risking damage to your engine. If someone fits an aftermarket LPG system to their BA they are voiding their warranty on the engine.
Parnell, and perhaps others, do offer a warranty to cover damage to the head and valves etc, but from our testing there is much more damage that can be done to the rest of the engine that is not covered by the warranty.
