K24 SC 500Nm, 367 ft/lbs
K24 SC 584WHP partial tuned
This motor has now been fully built in house, using a combination of custom and off the shelf parts imported from the USA. It features 88x99mm bore stroke, 38mm inlet valves, improved CNC porting, and of course the larger plenum RRC manifold. Also fitted is an adjustable exhaust cam gear.
Tuning will now begin to understand the changes.
The dyno graph on the RHS is after initial tuning. This is compared to the previous motor in the dotted line. The gains are better than we hoped for.
The motor is fully tuned to 5000rpm. Above this rpm is only partially done, as the water injection needs to be upgraded to 3D mapping which will take a few weeks to develop (hardware and software). The Exh Cam position has not be optimized yet.
Also note peak boost in the inlet manifold is only 16.2PSI, down from 18,6PSI.....and making more power!
The cause of this has yet to be located. No doubt its the bypass or waste gate blowing open beyond 14 psi boost.
