You could run 15 PSI or more , if the engine does not detonate.
If you want to just run low boost & are not expecting to make a lot of power.
You can still use the turbo I recommended & keep the boost low.
7-10 psi would be doable & very easy.
10 PSI on a stock 230 engine,,,hmmmm, hard to say, what size carb? it will vary a lot. 180-330 HP range at the flywheel as a guestimate.
Depends on what mods you plan on doing. Head work, bigger carb, different camshaft?
If you are saying keeping the 230 all stock basically & add a intercooler & turbo? 180-200ish HP.
The torque is what is going to go up much more than HP when adding a turbo & not doing anything else.
Also, torque it you would feel the most when you are trying to accelerate. That is a plus to have gobs of torque & that is what exactly what a turbo will do for you.
