to be honest though, very very few will see 350 from a ko4 hybrid. 330 seems to be the typical figure most will produce.
To my knowledge (in the UK - not sure about Dougs stuff in the states) mine is the only one that's produced anything above 350, with hardly any others reaching 340, so a safe assumed max for the ko4 hybrid still really remains around 330-335 as it was 3 years ago
Exactly - Nail on head.
Unfortunately, yours is the ONE which gets banded about as having done 350+bhp... (including you in your siggy, lol)
Doing it Once, then turning it back to a "safer level" proves what exactly?
I could say our lupos 332bhp k03 hybrid.. but no.. its not in reality although it has done it.. Its 300bhp solid, and 332bhp if turned into the stupid hot level.
People latch onto the fact the power has been achieved once, on a cold run, non repeatable but then sent out on a lower level....... for reliability.
the vast majority of k04 hybrids make a little over 300bhp, and some venture into the 320-330bhp range.... Realistic Dyno figures. Not fictional airflow based ones from logging alone.
For the ~OP, invest in wmi with your hybrid... Essential ingredient for 1.8t's imho, especially small hotside hybrids. It will help you realise it potential safely
comparison of a couple of very similar hybrid spec's one lcr one agu (prawnys as the gauge reference)
You can see the boost and torque difference between them, and ones road car and the others track car, which will spend its time getting ragged on track, so appropriate level of tune to keep it together, that and no egt protection possible in agu ecu, unlike LCR. It is possible to get these figures as you can see, even on a tight **** dyno like mine, but the dice needs to be stacked and all boxes ticked for decent mods, added properly.
USA/Dougs figures all fall into US happy dyno category, where they all seem to make atw figures where we get @fly figures from same hardware, same boost etc etc.... Accepting that for what it is.
eg below:
The tell tale for where inefficiencies creep in are where the mass air flow divide 0.8 correlation diverges, and this is where large, usually heat effect inifficiencies creep in.. Pushing a lot of air thru a small turbo hotside.
Its all about the flow, AND thermal management
tick these two boxes and it will be as good as it can with suitable mapping encouring it to do its thing.
