origanal stats for the boost pressure of the Thema 2.0 16v turbo

[kassus]

I'm trying to find the origanal stats for the boost pressure of the Thema 2.0 16v turbo. Could anyone help ?

[Ewan Henderson]

i have the owners manual for my thema and it says the boost should be 1.6bar but this must be a mistake because that would blow the engine up. i think its meant to be 0.6bar, thats about 8psi. you could maybe help me. my car only gets slight boost at about 2.5k, and does not come in fully untill 3.5-4k. is this normal for these cars or do i have a problem?
cheers

hi ewan

the manual says 1,6 because its atmospheric full pressure. you must substract 1, so the pressure is 0.6 bares in normal mode (first electrovavle and continuous mode). with the second electrovavle and full overboost it reach 1 bar, but just for a little while (about 60 - 90 seconds).

if your car have lees boost maybe you had broken the overboost system. try to check the electrovavles near the air filter.

best regards
