Anyone have access to a 964 plastic intake?
 

Hello all,

Does anyone have access to a 964 plastic intake (preferably removed from the engine)? Please can you take pictures of all angles and include all measurements on it? I would like to fabricate one from stainless steel, improving the documented inefficiencies and adapting it to fit my vehicle.:D

I do not want to use a plastic intake with adapters.

Many thanks in advance,

F.

Do you have any info on these "documented inefficiencies" ?

Hello Chris,

There are a lot of info in other threads. Lukesportsman provided me with this info:

"You could improve on flow at the intersection of the runners to plenum. Many have argued that the stock TB and opening are restrictive."

as well as:

"If your plumbing your own runners (tubes) into a fabricated plenum, you might consider 180 degree rolled lip trumpets extending into the plenum. There have been studies showing an increase in flow by installing these small trumpets inside a plenum as if exposed to the atmosphere."

These will probably be the biggest changes I will incorporate :D

Hope this helps,

F.

Do yourself a favour and call Steve at rennsportsystems. His number is 503 244 0990. I have talked at length with him about various intake systems and their applications. If I knew then what I know now I would not have went with the basic jenvey set up I posted pics about in one of your previous threads.

Call and ask him about some of the options, you will be glad you did. :)

Cheers

I dropped Steve an email, no reply yet...

Anyone willing to do the measurements for me please? This would help me determine cost/effort involved reproducing the 964 intake manifold vs. some sort of ITB setup :D

What would you have gone with, Jeff?

I was a bit shocked to hear that myself. Why the change in attitude? What direction would you have gone Jeff?
