Yes tons of people run around 10 psi or more on stock internaled D series. But in all honesty you need to read up on some things. This topic is cover all the time... engine failure doesn't occur with XX amount of psi but rather when too much power is being made. D series normally run between 180-230 hp on stock internals when boosted to be safe, but some have taken them up to 300+ hp on stock internals. Power is dependant on many things and not just psi.
