Somebody could put a taller tire say 45 instead of 40 on the wheel and made the gap look smaller giving the perception that the car is "lower"

up to 0.7-0.8bar it was running perfect but
above that I think evaporator was unable to
produce apropriate gas pressure at high revs

I was thinking of changing injector nozzles,
shortening hoses between injectors and nozzles
and so on but the result is I got rid of it
and I'm happy

rumours are that some succeeded in having
stock power on LPG but personally I never
saw such car

switching between fuels was very fast and you
hardly noticed it so usually it was like LPG
cruising and Pb98 overtaking and speeding

very cheap but with it's own limitations


noticaeble

yes we had sport springs, it's the same part no
as for S6+ for which sport was the default

or buy lots of "NOS inside" stickers

or are they different spring rates? Progressive maybe?

Are there part #'s that should be stamped on the springs to tell the difference?

In Thailand ,there's a lot cars put the LPG in.Due to the rising up of the gasoline price.So peoples are no longer insist to use the 95ron,Even there's some alternatives for the gassoline use that is using the Ethanol additive.

There's a lot of experts about LPG in system in Thailand.You'll not belive that the 1JZ-GTE,2JZ-GTE etc is also able to use LPG (Some on sequential injection,some on the Fix mixer system and probably adding the lambda ctrl on)

IMO,I have one E39 BMW with the sequential injection.I can only slightly feel that the power has been dropped.It's around 3-5%.and the top speed is still the same.and I couldn't notice when the LPG and Ron95.

Anyway,Because LPG system has no any pump like the Ron95.I don't think it's good for the higher boost.As you will see that when the LPG is remain lesser in the tank.(5-10%).You'll feel the power has been dropped significantly.

Thanks for the info.I heard OMVL in Thaiand too.Is that from ITALY?I have AUTRONIC on my E39.

Yes OMVL is from ITALY, 5gen LPG installations have liquid gas pumps
