964 vacuum lines help

[964_c2]

hi

just trying to hook up all the engine vaccum line correctly after have motor out and find my camera has crashed with the images i need!

can anyone tell me where the vacuum line from the vacuum unit that opens the lower flap in the intake manifold "pic" goes too?? is it to the canister near the air filter box? car is a 92 c2 plastic intake motor.

is there a diagram with all the lines available?
cheers

Bill,

Being one of the resident 964 experts, do you think the small vacuum reservoir is adequate for sustained full throttle running? The reason I ask is my car always feels a bit soft on the top end after 15+ minutes of track time. I was wondering if the reservoir could be depleted after sustained full throttle running preventing the secondary flaps from opening? Plausible or would deceleration help generate additional vacuum?








964,

The white nipple you circled (on my car) goes to the circular vacuum reservoir in Bill's second photo. The black nipple goes to the lower flapper.

I added an extra vacuum reservoir to my track car just for that reason. On a street car I never had that issue

Bill,

Do you have a picture of your set-up? I imagine you just simply 'T' off the feed line to the extra reservoir?

Thanks for the insight.
