This is why I reckon it's only worth fitting if you have an engine that
really needs it. The gains in efficiency compared to closed loop single
point *IF* the latter is set up properly are slight, and it'll take a long
time to pay for it, if ever.
Now, if you could set up liquid-phase gas injection, it'd be more likely to
give better results - would also not need a vapouriser. I keep wondering
about trying this in a petrol injection system - the old Bosch K-jet runs at
about 5 bar, ISTR, which is not that far off LPG liquid pressure. It'd need
recalibrating, is the main drawback, which would probably preclude runnign
on petrol. However, that doesn't mean you can't have a second injection
system which is what you get anyway with SGI.
Dunno if anyone's doing anything in this respect.
