My custom intake plenum
 

Well I've heavily modified two turbo intake plenums in the past.

Here is my project I've been brewing for a LONG time finally starting to come together.

Radius for the runners
Attachment 15971

Attachment 15972

Plenum body with tapered and angled neck ready for 60mm TB
Attachment 15973

Attachment 15974

Attachment 15975

Tapered runners - tapers by 2.5% to increase velocity
Attachment 15976

Attachment 15977


Flange ready to be machined for injectors/fuel rail. I was going to use a hacked off stock flange but I didn't like the abrupt transition.

I seriously looked up the word "plenum"=D
Never used that word, Always learning..
Gorgeous btw Fric.

Beautiful! I want one. Where did you get the metal from?

Looking great, man!

Wow so nice!

very nice!! where did ya get the flange from, the rest i can source myself. i too have a few stock manifolds laying around i was gonna hack up for the same purpose. i have a exhaust flange but the intake ones were always specialized and had injector stuff in them

Nothing is going to be stock on this. I'm ditching the stock flange as I didn't like the transition. This is a completely custom manifold.

Lol so where ya get that flange from. The flange from hybridz I saw is very expensive and had injector ports in it and was very thick. Meant to go as a part of another group of parts I didn't have the wallet to purchase

My flange was cut on a water jet and will be beveled and machined for the injectors. The fuel rail will bolt to the flange to hold the injectors down.

Go, Fric! Beautiful work.

Hopefully I'll have some pics in the near future with the fuel rail and injectors. After that she'll get welded together. Just trying to figure out how I want to finish it. Polished, anodized, powder coated, etc...
