how much boost?

[grayg40]

hi all, just an enquiry but how much boost can a G40 engine take?

they cope with 21-23psi just fine.  All depends on the fuelling.

cheers,
its just cos i have aquired 3 chargers from work and they will fit in the hole where the charger goes. they create 1 bar of boost but if i am to reduce the outlet side to G40 pipe size it would probably produce about 2bar.
if i can get this to work on the G40 i would make up a parts list and sell the other 2 as i can get spares from work.
