anyone make their own plenum for dbilas ITBs?

[firefirefire90]

I was curious if anyone has made their own plenum with runners and such for the kit? The plenum I'm sure works great, but looks quite boring in the engine bay.

Any thoughts?

stock plenum



desired S14 style plenum

I'd talk with JP @ A1 Autowerks up in your neck of the woods (San Rafael).

Here's a box he did for a M10/S14 hybrid with Jenvey ITB's.

called them right as I read your post, and they picked up the phone and I talked to JP. Cool guy, and even offered to come to my house first to see what he's working with! Thank you for the recommendation!

No problem, be cool to see how your car turns out.

make one of this ones, it was fun to do, video ... http://www.youtube.com/watch?v=8D1basq0RTk&

or a carbon airbox at 790 euros, it requires Brake Booster removal...

notice lack of brake booster and angle where throttle cable meets mounting point, looks different there.

Are these intakes available for the dbilas somewhere as I struggle to think that the unit supplied with the intake manifold is the best for the a stroker engine. Especially when you compare them to a S50B30 or S50B32 euro plenum's.

that dbilas one is shit they all are and pretty much everything in the kit is, the manifold, throttles, etc. The thing about a plenum is its size/volume and the distribution of flow to each runner. on an I6 it is not as simple as people think to makes sure that flow is equal in each runner and usually people think it is runner 6 that sees less but this is quite often not the case

just added nips for pre throttle readings, they may change with various runner lenghts, it's crude but it works., easy to modify, add or substarct to it, etc, basically a running mock-up that clears brake booster.

icv it's sucking hot air, someone's pantyhose plays filter and crank is venting through a e36 brake booster valve., excuse the octopusiness, lol.

here's a few manifolds designs from diffrent cars ... http://www.bimmerfest.com/forums/album.php?albumid=7662
