how can i get enough vacum for a servo if im using gsxr t/b's on a home made manifold on a silver top zetec ? use 4 take offs from the manifold or run a vac pump ?if so which one.any suggestions

My bogg's manifold only has the take off on one runner, they said that was plenty, and linking the runners with the servo pipes would effect the engine's running.

You don't need a servo in an Indy do you?

They aren't normally used and Mine certainly never needed it

Just pulling off one runner will be sufficient - the servo chamber is its own vacuum resevoir anyway.
