KKK K26 Turbocharger

[CHB]

i got myself a KKK K26 Turbo but i cannot find it's specification on the net. any one has experience with it? ie: efficiency, boost, response and etc about it?

[indeecent]

There were several versions of it, mostly on porche/audi production cars?

what model did your car come off to get a more specific answer

but going off what i can see from a few searches (nothing concrete till you know what version)

peak efficiency was about .74, with a pressure ratio of 1.6ish +-0.15, so thats what... 8-9psi @ around 0.8 - 0.12 m^3/s

efficiency drops rapidly after about 2.2 PR, so anything over about 16psi would not be advisable

type the serial/model number into google, i did it when i got mine.

[CHB]

the name plate shows

035 145 703E
K26
87 082 2319
5326 970 6410

which i have googled it and found nothing about the inlet and exhaust housing information but know it is from Audi

[indeecent]

the 6410 on the end denotes a compressor inducer vs exducer of 64%, and the version of the turbine 10th series.

kkk use a different way of numbering their housings, with it being a 6.95 (?) yet a 4.10 could be bigger, and a 5.1 being even bigger still, so I'm not sure of how the relationship works

exducer = 66mm
inducer = 42.24mm
trim = 41
exhaust outlet diameter = 2.20"


(should be pretty close to your one i think)



btw, thats a fairly old turbo isnt it? mid 80's? possibly from a quattro?
