Dual Intake

Someone try it, I want to know if it works and what it does to the air flow sensor.

It has definitely been done before.

Lets say an engine needs an 80mm wide throttle body to get the amount of air flow it requires. It could be shoved all into one throttle body or distributed evenly across multiple throttle bodies. Multiple throttle bodies are usually preferred since it helps to even out the distance the air has to flow to each cylinder. Thus preventing one cylinder operating more efficiently than the rest.

Back in 1963 I had a 1962 Austin Healey 3000. Came from the factory with trip carbs, One more than the '61 models. Thinking that if 3 carbs were better than 2, then 6 would be better than 3. Without going into details I fabricated and installed 6 Mikunis on the thing. 1 carb per cylinder with a 2inch runner. The linkage was a mechanical nightmare At this point I forgot about adding a turbo which was in the original plan. I was happy just to get the thing running. There was a noticeable improvement on the top end but a very bad bog on the take off. Everything was mechanical, no computers then. I'm thinking that with the improvements we have now and using TBI with computer control it might be a viable option. Would sure be fun anyway.

I question how the two bodies would be able to sit so close together. and manage linkage.

 

The one alexia posted for reference has them about 4" apart and is not even a stock intake.

Yep, with carburetors and throttle body injection, wet instead of dry manifolds, having multiple throttle bodies helped since the wet air fuel mixture would distribute more evenly.

 

Also, Austin Healey 3000! :drool:

The linkage arm of the rear most throttle body is ditched. A longer rod goes completely through both controlling each throttle body from one linkage arm. So the throttle position sensor will be fine. Idle air controller, well, I guess start with one hooked up, then try both.
