The Weber DCD carbs are dual inlet and staged throttle. Like this:



Does anyone know of a throttle body manufacturer that makes a replacement for this?

Jenvy makes these, but are not staged throttle:

Twin bodies DCNF style - Jenvey Dynamics

Do what some people have done with Holleys !! gut them and turn them into throttle bodies , add injector bungs on the intake manifold and then figure out a way to mount the TPS , does the throttle shaft go through the carb and out the other side ? if it does then TPS mounting shouldnt be that hard. It takes the headache of trying to adjust primary and secondary throttles on after market throttle bodies as these already are set to run this way.
Modern day EFi with Retro looks its a win win !!!!!!!!!!!!!!!!!!

Great link on that website. I would assume that what ever engine management you are running with this would be able to compansate for the staged fuel delivery

its the same thing as tuning any factory throttle body or a 4 barrel set up !!! dont worry about tuning its a piece of cake mate !!!!!!!!

unless i'm misunderstanding something, i have to agree with Cfamilyfix. when you introduce engine management into the equation, why would staged throttling matter that much?

Staged fuel delivery is the same as any fuel injected 13B.....they all have primary injectors and staged secondary's. No issue at all with tuning.

I have to run staged throttle, I'm using a Rotary Engineering Intake manifold, the primary throttle plates open up and feed my streetported primary intake ports, then after half throttle the secondary throttle plates open up and feed my bridge ported secondary ports....as well as my Semi-PP ports

Here is my Intake manifold:

Oh also hood clearance is becoming an issue, the carbs are very tall and I have no room for any sort of filter.

A simple throttle body would be much shorter.
