only low boost with powerworks sc help please
hi guys i need some help with my powerworks supercharger.
its fitted to an 2 liter black top zetec. today i hat it to a live mapping and result the was very bad it made only 3,4 psi boost and 190bhp.
the powerworks kit is new and was never fitted before and should make 13 psi.

David82st200 08-31-2012 03:26 PM

How can i Check it?

Bypass valve is stuck open. Pull the blower off and see why it wont shut.

David82st200 08-31-2012 03:57 PM

Have i to remove the complet charger or only the Upper half?

What live mapping are you doing , a pis poor tune will do this as well

It was the Bypass Valve now its working fine.

I had it on the dyno because i couldnt find an tune for the powerworks in Germany.
And when you see that engine makes 190 bhp with this minimum of boost im sure that it will make with the full 13 psi much more then the 230bhp from the powerworks tune.

I bet it felt pretty good with 190hp. Thats 50hp more than stock.

David82st200 09-01-2012 10:58 AM

Thats only with 3.4 psi
