Ah, so its 1 bar at about 4400-4500 rpm. Thats not too bad for basically a 2 ltr engine.
Maybe the compressor wheel is a big big for this hp? Compressor wheels determine spool almost as much as the exhaust wheel.
What turbo is on it atm?

This combo could/should do a little better as head size and cam seem ok for 300hp at 18 psi with these low inleg temps. Maybe timing has been kept a little conservative?
'75 Super.
