If the S/C'ed VG33 REALLY does only run at 7 psi, how could there POSSIBLY be ONLY a 30 HP difference (given that 1 psi ~20ish HP) if the CR was the same? This is common sense...

However, I agree with potroast in that 8.5:1 is a bit low in my opinion. The VG30DE runs at 10.5:1 and this might explain the 222 N/A HP. Given, timing is affected as well as quality of fuel has to be reconsidered, but I do believe Nissan could have reworked the VG33 for a bit more power N/A if the CR was raised slightly...
