not sure if this should go in here, or the forced induction section, but here goes: why has no one taken a dual carb style intake and used it with a twin turbocharger set up? I know it would most likely NOT work on a 4th gen F-body, but I have yet to see one company/person attempt this. Would the gains of something like that be too little for the headaches that might accompany such a project? And if someone did try it, would a high-rise be a better option than a low-rise? Would this even work on a small block, or would a person need the cubic inches from a big block to utilize the amount of flow that could be possible, if any, over a single inlet style intake?

You will have to forgive me if this has been asked before, but after spending the weekend searching through all the forced induction threads and trying all sorts of different key words, I could not find anything on this, and I am just down right curious about it!

 

What your saying can be done. I'm sure someone has done it. People who have run the Buick Stage II (4.1 race block) have done it for years. What you have to account for is air flow. A carb intake is made to take air stright down so when you put a 90 deg turn on top of it from what I have seen you make the rear cylinders leaner than the front. No big deal to deal with as long as you have a sequencial (sp) EFI. Buick because of production numbers don't have the broad market say a Chev motor does.

The intakes on all the newer cars with EFI take air in from the front and are designed to spread the air and is easier to adapt to either a procharger or turbo application.

This is just a down and dirty version of what I have run into and would think would apply.

Take Care

 

I am not sure I understand what you mean. From most of the threads I sorted through on turbo builds, it seems that the ones that made the most power were running a single plane intake with an elbow on it, kinda like this



If what you are saying is true, then wouldn't having a set up with two of these be more efficient? Even coming from the front, instead of through the firewall, my thoughts would be that this would be an extremely high flow set up. I am sure it would not take much to get two elbows welded up slightly turned.

 

All I was stating was that (look at the photo you posted) the natural air flow on the photo would let the front runners of the intake would get air easier than the rear ones. Either way you mount the elbow the one side will see air flow to one side easier than the other. Air is like water it will flow in the easiest way.

The photo you posted I would guess has an intercooler mounted in the passanger side seat and that is why it comes in from the rear.

 

right, I understand what you are saying. However, I think what I am not getting is what you are trying to say. By looking at the picture I posted, or any picture using a set up with an elbow like that, are you saying that in that set up one set of cylinders, whether it be the front, rear, left, or right side, will get more air easier than the opposite of it? Or are you referring to if it had two elbows, such as on a duel inlet intake style?

on this picture here, lets say each of these had an elbow on it, and each was fed by a turbo as in a twin turbo setup. Or lets say there was only one huge turbo, a 106mm, and the tube off the compressor side split into two tubes, each feeding one of the elbows. Now this brings me back to my orginal question, wouldn't that be more effecient than the single inlet? Shouldn't it be possible to fill the cylinders more effeciently and possibly even more evenly?

 

Yes you are understanding what I meant about a single elbow. Now with a duel elbow it might work better, but that I have not tried or seen one done.

 

What would be the advantage?

that is what my orginial question was asking, if there would be any advantage to using a set up like that?

 

yes, you are understanding me correctly.
