Looks like would be around 200-220rwkw @ 4500rpm
With a 2.8 stroker, cams, manifolds (and who knows what else)... 24psi to make ~360-380rwkw.
I think ouch...
Comparing them to "-5s" they have a much tighter trim wheel on the compressor side (less flow), but larger exd wheel. So potentially would explain why they dont make the top end with such a small trim not getting the air in.
Simlar rear to a -5 though, just larger trim so effectively more flow, and lag. Add in journal bearing as well...
I am not of confidence having seen that PDF
I wonder why they didnt compare the R34 N1, and chose a 20yr old R33 N1 lol
Still be interesting to see the results none the less.
