Carburetor with turbo?

[1346w]

So I've read all the threads on here about turbo'd C models and the lack of stc's and so on. I've also done all the research I can find on the internet about the subject, but still lacking a understanding. My question is, what are the turbo C model guys running for a fuel system? Is it a modified carburetor, blow through style like something similar to automotive or a draw through style? Maybe a enclosed carburetor with a box or even a Ellison style throttle body?

I'm far more familiar with automotive applications of turbos and their workings with fuel injection and carburetors, so the injected E & F model airplanes I can understand, but the carburetor models I'm still unsure about.

Look a little harder...

You will find a kit that takes the usual TN, and plumbs it to the carb...  that’s not the challenge...

There is an STC for that that covers the installed devices...

What is missing, is the ability to add additional birds to the STC’d list for SOME cases...

The STC for Mooney installations has fallen with an owner that has recently passed...

So... not a technical challenge, but more of a legal / paperwork challenge...

Got any legal / paperwork skills?

Yeah but does the turbo blow straight into a stock unmodified carburetor?

I guess I can ask a more technical question... When turbo normalizing a carburetor, is it necessary to do anything to a carburetor as long as you don't run anymore manifold pressure then a engine would produce at sea level?  Hence the normalized, not charged.

As an example take the TO-360 on a turbo piper Seminole.  It has a turbocharger blowing through a carburetor designed just for the task.  Not a lot of changes but some are very important to the operation.  Most of the problem involves the venting of the float bowl and the accelerator pump.  Also the hot air provides some challenges.  At least you don't need carb heat...

We have a turbo guy around here that is excellent for answering questions...  the set-up for the carb is different than what i posted here...

You might want to explain what you have and what you are trying to do?  

Do you have an M20C?

Do you want to add a turbo?

If you aren’t changing the compression ratio, expect that TN is what you are getting... not TC.

From memory (I used to have an M20C with a Rajay) it uses a blow through system with a different carburetor that is vented to the pressure side of the intake system (sees above atmospheric when turbo is operational) and a different fuel pump that is also able to reference the atmosphere of the intake system to keep the pressure needed to get fuel into the bowl. I hope this helps. Cheers, Chessie
