Why do you keep comparing your setup to other setups?
With such a high CR how can you? It is directly related to knocking issues, saying this car runs X amount timing up top and yours is less is no comparison.
And no knock detection? Standing by the car doesnt cut it! With exhaust noise, gate noise, spool noise, how would you hear anything at all?
Why would you run 2 different pumps and Y-Piece them together?!
I had my first engine built but a guy who did mostly V8's. It lasted 8,000kms.
