Well yesterday I took my k26 apart to inspect it and well im just nosey
Ive always thought there was more to extract from this turbo/set up but thought 2 of the main things holding me back (figure wise) was 8.5 cr and hotside restriction (possibly wheel size or ar of the housing)
Just me being me have always thought of what was possible with this tubby or framed size on this car with some subtle changes, as got a friend weighing up what could extract out of it?
Heres a few pics of the wheels and housings
Compressor side
Hotside
Hotside housing
The obvious upgrade would be a newer more modern and efficient billet wheel which would in effect need less energy to turn the turbine?
The main thing that I would have thought should gain some is a bigger ar turbine housing or something of that nature to aid hotside flow
The manifold seems to flow enough and the flange port size is in between a t25 and t3 so that shouldnt be holding it back? When was on the dyno Bill did say looked like the hotside was the restriction as could tell that was where the heat was building up first
Just after opinions of what this could perform at on a higher cr set up or (what would expect the wheels to perform at due to size) and also sensible upgrades as believe theres some more gains to be had out of this turbo
