S320 CDI pressure
I posted this on the W211 forum, but I suppose a European fan might have the answer here too:
Does anybody on here happen to know the boost pressure for the 320 CDI engine? I'm not talking about the 23,000 psi fuel injectors, I'm talking about the air pressure from the turbocharger. One dealer I talked to said, after translating the number from some obscure unit, that it came to 36.2 psi, which sounds awfully high, as he noted. Somebody else told me they thought it was about 7 psi, which sounds low. By comparison, the roughly comparable BMW 3-liter turbodiesel runs about 22.6 psi on a 17.0:1 compression ratio to produce 228 bhp, so the 320 CDI should be in that range, one would think. Any thoughts?
