(YES - I did a search and found nothing that helpful)

First question: does the "16," "24" etc. actually refer to some physical property of the turbo? Number of vanes, internal volume, flow rate, etc.? Or is it just a model designation?

Second question: in the case of a "K16/24" hybrid, does this mean that the turbine is from a K16 and the compressor is from a K24? Or maybe it's a K16 inside a K24 housing? Pretty clueless here...

Third question: Is there any way to tell what internal modifications are being done to hybrid setups?

Sorry if this is remedial - I'm pretty damn confused...

 

1st question:

2nd question: It's essentially a K24 compressor inside a K16 housing.

If it's a "Zero Clearance" turbo..it means that the compressor housing is coated with an epoxy that is sprayed on the surface, creating no space between the compressor wheel and the housing (the wheel is actually stuck in the epoxy). The housing is then backed off and the wheel is spun at high speeds to dial in the clearance. After the process is complete and the desired clearances are achieved...a coating is sprayed over the epoxy to harden and protect it.

Third question: Unless you're a turbo expert, really the only way to tell is to ask the particular tuner(s) how they're setting up thier turbos.

 

I was daze and confused at first too. But u will get it soon enough.

 

Thanks guys! Is there a primer on the topic anywhere? I did some basic reading on the net but it was all pretty basic. I also bought a book - "Desinging Turbochargers" or something like that but it's a freakin' science textbook...!

 

Thanks for asking this question it greatly helped me as well!

 

Dont the numbers usually mean the diameter in mm of the turbo wheel? And the split numbers show the intake diameter vs. the exaust diameter? Thats what I always thought it applied to all turbos this way. I know the T series turbos do this. for ex. the t86 has an 86 mm wheel, and so on.

 

I don`t know man.....16mm is awfully small for a turbine AND compressor. BTW that`s less than 11/16 of an inch!

 

I was talking generaly for turbos. The really small numbers (less than 20 something) obviously stand for something else. But I know the k26/6 in my 951 looked like the turbine was about 26mm.

I know the T series turbos are the size of the turbine though. Im not sure about the KKK turbos but maybe some are.

 

The K26 that came off of my 930 is totally different than the K26 off
my 951.
