Ralph Sarich's orbital company did the development of the
Liquid Petroleum Injected six's as commissioned by Ford. Ford went out of their way keep the results quite. They own the Tech.
They were producing that much HP form
naturally aspirated injected LPG that they were blowing the bottom ends apart. Without turbos on them!!
Ford then supplied them with
Ford
Performance
Vehicle bottom ends to continue the R&D.
Keep in mind the very high octane value of LPG. Higher octane means higher permissible compression ratios, which is
one of the quick square roots to performance.
It instantly drops massively in the temp as it expands at the injection point providing a multitude of benefits for a cooler denser charge which is more compassionate to the valves as well.
They were producing more output than the of the floor
Turbo XR6 petrol range. Couldn't have that,
So for production, they detuned them. Although in of the floor trim the LPG still puts out considerably more than its naturally aspirated
petrol counterpart. Detuning also meant that they could run the lower budget end running gear to get the production costs down.
The Lpi XR ute bike carrier range is a real cheap fun option, for those not needing a 4WD. Its not hard to pump them up toward 300KW without a Turbo. It is said they were intentionally
underquoted standard trim at around 200kW/409Nm, but in actual they dyno at 210KW before you touch them.
Sadly though one needs the turbo ZF box of at least the input shaft as well as a bigger diff. As of the floor they start to fail at around 250KW. So head shave, exhaust and cold air intake and and tune to just below 250KW with premium lubes as a cheaper option. Cameras everywhere anyhow

Lots and lots of fun and dirt cheap on fuel dollars and cheap to replace if it all goes pear shape.
