How did you guys run your vacuum lines for your saab setups?




On the inside my car looks like a fighter jet.

Wastegate to vac source like intake manifold, t off and to the bypass valve

But how is the brake booster, fuel pressure regulator, and the other lines ran? Isn't the large port on the turbo for vacuum? Its the same size as the brake booster hose.

Post a pic.

I cant recall what line your talking about.

I think I know the one but a pic would help.

Brake booster and all that goes to the normal position. Fpr to vac source on intake manifold. I believe the big nipple on the turbo can be used for a pcv vent if a catch can is installed on it.

The line is sitting on my master cylinder. I believe its for the HVAC. I was told the brake booster had to go to vacuum. If it is connect to the manifold it will see positive pressure. I am pretty sure there is a check valve built into it but doesn't it need to see vacuum all the time?



here is a picture of the turbo. The fitting I am talking about is above the filter.

The little vac line I believe goes to vac.

The brake booster goes to the stock spot.

You wont be boosting and braking at the same time.

The other should go to a catch can iirc it goes into the inlet of the turbo. If you put your brake booster line there youd have little to no vac when your trying to stop.

Thank you. I will post if anything catches on fire or blows up.
