          we have one on a urs4 with very good results and another just about to go on a coupe which will be on the rollers shortly after.

            Looks sweet!!! is it from the focus rs 4cyl or the 5? another nice idea for the k24-7k would be ball bearing it. cheers!

                  Sounds like some interesting internals... this would essentially be another type of small hybrid I suppose... Be interested to see some dyno numbers - could be good bang for buck there if it makes reliable 300bhp on stock injectors and to know what is maximum recommended boost profile. Could it run to say 1.7 bar in the mid range for high torque then hold onto ~1.1 at the redline for example ?

                  Is there a reference price to refurb and upgrade a tired old K24 from an S2 to this spec along with a 360 degree bearing ?

                    Time to get that old K24 of mine out eh Paul

                    Kind of wishing I'd held on to it now as it was definitely better than the one in my avant which is now howling abit..

                      the comp wheel has far more modern design and 40% lighter so the spool is FAST
                      been running 1.5 bar dropping to 1.2bar and feels easy 300bhp should have some dyno time coming up soon so I can see what limits are.

                        1.2bar at ~6000rpm should be over 300bhp unless air temp is very high... Definitely sounds interesting here at that price. Would need to see dyno results though and know if it can be pushed for 1.7bar in the mid range for more torque than I have today.

                            Mine's nearly 300bhp at 0.8 bar so 1.2 is going to be nice and healthy for sure.

                            With one of these, an RS2 EM and some RS2 injectors (to add to the 3" zorst, RS2 IC and modified inlet) I'd hope that the Alpinweiss would fly nicely, for £1k (with a generic map perhaps?) that's good bang for buck above the 300 ponies region, £1.5k max, hope for 325-350 with lighteneing spool (ideally a bigger WG spring to make part throttle response better too).

                            What's the torque going to be like though, are we into RS2esque rod-bending territory if you push it lower down or does the 1.5bar limit on the MAP sensor keep things nice and sensible?

                            I'm sure that someone with some compressor map knowledge and maping capability would be able to make this a great upgrade.

                            Also, does the stock centre section and turbine mean that fitment and oil/water lines are 100% as OEM?

                            @Paul, perhaps that small hybrid dream is a little closer!
