k26/27 hybrid turbo

You aren't the only one with one of these... I'm sure I've seen reference to the MD147 name before. Maybe with one of the guys down under running with a conversion kit he imported from the UK.

I strongly suspect that Mihnea will know the internals. He can map that sucker (sorry blower) as you like...

400bhp is about the normal limit for a K26/27 hybrid - tis confusing though cos of the various differences in turbines and compressors. Makes me wonder if any two K26/27 hybrids in the world are actually the same ;-)

so you recon thats about the limit of that turbo ? or do you think more can be had ?

**Jamo** · 22 November 2005, 17:35

I'm sure Greg knows something about that turbo

**Mihnea** · 22 November 2005, 18:23

No way that turbo can EVER do 400 BHP, not even in KKK's top engineer's sweetest dreams. A few of those that I have mapped do around 320-330 BHP, another one did 360 and that's the highest I've ever seen out of that turbo.

Regardless, I'm still open to see if ONE turbo will do 400 as every car is different, but I'm not holding my breath....

HTH,

Mihnea

its bigger than rs2's is it not ? and if so can you get that out of an rs2 ?

**Mihnea** · 22 November 2005, 18:33

The cold side is marginally larger (27 based compressor wheel, RS2 is 26), the hot side isn't as good as the turbine wheel is back cut...

an RS2 with a decent cat-less exhaust can do around 370-375HP.

**volcano rs** · 22 November 2005, 18:45

what are you basing that on ? what mods along with that turbo ?

**Mihnea** · 22 November 2005, 18:47

Full turbo back exhaust, intake mods, blah blah blah blah and hours spent mapping...

**volcano rs** · 22 November 2005, 18:52

its hard to believe its that bad . best to have a rs2 turbo then .

**Mihnea** · 22 November 2005, 19:19

Honestly, YES. Now if you want real 400 HP without headaches, the same turbo as Doug's or Tom's will do a great job, with a good potential of 440-450 HP maybe more on a tubular exhaust manifold....

**volcano rs** · 22 November 2005, 19:22

is it still based on k26/27 ?

**Mihnea** · 22 November 2005, 19:27

yup

same EM/DP fit...

**volcano rs** · 22 November 2005, 20:38

so they would rebuild mine or a new unit altogether?

There does seem to be a bit more top end with the MD147 compared to RS2 turbo on engines with similar setups
