Hello i have an S2 from 1986. The car has a lpg equipment and works very well on standard boost ( 0,7 bar). I want to increase the boost pressure up to 1,0 bar ( 14 psi), and I know I can do it without having the LPG many problems because the octane number is higher. There 's a way to increase the pressure without reprogrammed ECU? If i act on the solenoid (amal valve) ,i have a chance to increase boost?

 

Pics show the LPG !

 

LPG is low on lubrication for your engine. Why have you switched. ?

 

i think fuel price per ltr is the key jano..

 

Love to see some pictures of an LPG rs turbo. Whats the fuel prices like there ?

 

While this is true it does not have to be the case . You can either inject a lubricant in upstream towards the tank or have something going into the engine via vacuum which many cars use. Of course with a turbo car, a one way valve would be required for this .

Do you have more shots of the LPG and what kit/type of LPG injection it is? I am guessing it is a mixer ring type? I understand that LPG has a higher resistance to knock but of course adding lubrication to it may indeed knock it down in addition to having a high optimum AFR ratio by quite a way over petrol.

But IMO alot of it will hinge on the type of LPG system you are using .
