Posted: Wed Feb 21, 2018 7:50 pm Post subject: KKK K26 compressor wheel technical drawings needed please |
|
|
Anyone have the KKK technical drawings with dimensions for the following compressor wheels?
2470 - have wheel - no KKK drawing
2660 - need wheel - no KKK drawing
2664 - wheel on its way - no KKK drawing
2670 - have wheel - have KKK drawing
They clearly differ in dimensions as the relative compressor housings all have differing part numbers. Would be great to see drawings and physical wheels to see the differences and what parts are potentially interchangeable if at all.
Thanks in advance....... _________________ 1980 931 - forged pistons, Piper cam, K27/26 3257 6.10 hybrid turbo, 951 FMIC, custom intake, Mittelmotor dizzy & cam pulley, H&S exhaust, GAZ Gold, Fuch'ed, Quaife

Just want to compare wheels out of curiosity. Dimensions. Shapes. See what differences exist. Check if my existing wheel is as the re builder said it was, a 2660 or not. Maybe instal the 2670 wheel I have, understand the machining required of the housing. Looking for facts not opinion and hearsay. Will pass on info to Cedric who is doing some efficiency modelling. _________________ 1980 931 - forged pistons, Piper cam, K27/26 3257 6.10 hybrid turbo, 951 FMIC, custom intake, Mittelmotor dizzy & cam pulley, H&S exhaust, GAZ Gold, Fuch'ed, Quaife

I got a 2660-4.1 turbo on the shelf and can take some measurements, if you want me to but not interested parting/selling the wheel only. _________________ Carl Fredrik Torkildsen

2660 compressor wheel
Height of tip: 3,9mm
Height from backplate: ~22mm
Radius of inlet: ~20mm
Thickness of blade: 1,5mm
Inducer: 39,8mm
Exducer: 66,0mm
Note: the backplate is counterbored and the flatback compressorwheel exducer is therefore in level. The 5326-123-2007 and 5326-123-2017 wheels are 5,2mm according to unknown (but trusted) source.
5326-123-2006, 5326-123-2016 & 5326-123-2035 are 7,2mm
5326-123-2010, 5326-123-2019 & 5326-123-2038 are 6,3mm
5326-123-2039 from 951 is unknown but also flatback. Worth to investigate...
5326-123-2201 from 951S is a superback but measure 4,9mm
