hi guys,
new to group was wondering if anyone has fitted a manual boost controller (ball and spring type) would any of you guys have pics of this for me to see how its done?

also does anyone know what the standard psi is on a 98 plate uk spec scoob?

thanks rob

Standard boost is normally about 0.5 PSI/0.7 PSI IIRC..

Boost controllers are normally connected to the wastegate actuator and the boost solenoid.

hi thanks for your reply do you mean 0.5 bar to 0.7 bar?

many thanks for your help im not that technically minded!
cheers

Nope, I think its PSI / Pounds per square inch.. On my scooby its Kg's / CM squared.. and if you work out 0.5 kg/CM squared to psi it works out to 7.111671654 exactly ..

many thanks for your help much appreciated

I'm not trying to be rude but these figures are b******s.

To convert kg/cm^2 to psi you multiply by a factor of 14.22334316 to be exact.

The boost pressure on my 97 UK car standard was peaking at 14psi dropping and holding to 12psi or if you prefer it in standard SI units multiply psi by 0.068947574 ie
0.96 barg dropping to 0.83 barg.
There are approximately 14.5 psi per barg.

To save arguments, do your conversions from PSI to BAR here accurately.

There is no argument my figures are correct

I'm sure they are Andy, but for the advantage of other people here who need to convert Bar to PSI and vice versa, I thought I leave a url to a conversion site, then there would no need for your expertees in math.
