What's a venturi, what's it do, and should I delete it?
I've ordered a vacuum line kit for my '87 944 NA, and in my research to prepare I've come across some references to a venturi delete.
First of all, what is a venturi? I take it it's a line of some kind ... part of the vacuum system? But what's it do? And what does removing it get me?
Is it only in turbos?
Thanks a bunch ... trying to figure out whether to add it to the list.

That is a brilliant thread. So perfectly clear. Too bad Mamoo and I will have to waste money elsewhere on our NA's as we have no Venturi to delete.

Get rid of it. It's not so much the venturi that is the problem but the numerous rubber vacuum lines that are prone to crack with age causing difficult to diagnose vacuum leaks.

Well, that thread said it's only in turbos, of which mine ain't.
Not to worry, though, money that would've been spent on a venturi delete will be spent elsewhere.

I know the NAs don't have them I just said that because of daniels comment.
spencer, I don't think a vacuum line will make that much of a difference. Lets reverse a shop vac and hook up to a NA and see if it makes more power

Did anyone see that post (I believe he was/is a member) that had a leaf blower forced induction set-up on his car (wasn't a 944). Spencer, that might be a good value mod.
