This is quite an impressive project, still didn't read the whole thread, but it's on the to-do list as i'm building something similar.
I watched the video from Daves world and I just don't understand why these engines don't seem to make any power.... is it the cam grinds or the ports on the head? I wish I had a shop and time to be able to explore the generally poor power produced by these engines. There has to be a bottleneck somewhere. They make torque figures but not HP which suggests flow problems at the higher RPM ranges.
Can you link the video?
Yes, they don't flow great at all in the higher RPM ranges.
Here's some dyno graphs from my car.
It's 0.8 bar boost (spring pressure) and 5 degrees advance, 1.35 bar and -2 degrees advance,1.55 bar and about -3 degrees advance.
The boost is fixed from about 3900 to the redline.
Temps started at 18C and climbed to 33C at the end of the run.
This was done on 100 RON in Europe, as we don't have E85 in my country.
K04 turbo, 525cc bosch injectors, no cat, 2.5'' exhaust, bigger intercooler and piping and custom home ported intake manifold. Stock bottom end, stock camshafts, stock valves and everything else.
It's really knock limited on gasoline, you can't shove any more timing into it to make real power like you can on ethanol.
But maybe it's just my tuning 😂, because everything is done by me.
are your tune logs a secret? Can we take a look at them? How much airmass are you flowing and at what boost?
