Any 370s running higher than 20psi?

Where did you come up with a 20psi number, that is absurdly high. You are not only going to get flamed, you are going to get nuked.

You can't run 20psi on a stock block 370z like you can on the Sti or Evo. Those cars have a low compression 8.5:1 ratio made for boosting. The Z I think is 11:1 ratio. With high compression your are already generating alot of heat and adding an additional 20psi is going to blow the VQ37 to kingdomcome. I think the most boost you can run on the VQ37 from what I've read is around 8psi max on 93 oct. and that's considered high. When I had my Evo I was running 22psi daily driven and 24psi when in race mode all on 93octane.hehe.

Just curious, how did the Mitsu engine hold up under 22psi/24psi? Any smoke coming out of the exhaust that was maybe darker then usual? I wish I had a dime for every Evo and WRX I've seen over the past few years that were burning oil at an alarming rate.

Nope never blew any dark smoke, or burned alot of oil. I would blame that on the tuning, and parts selected. The stock internal holds up to 500awhp before it needs an upgrade. Even though you can push 500awhp on the stocker that's not an everyday thing. I ran 22.5psi consistently on a daily basis and 24psi on colder days and that's on a stock td0516g/10.5 hotside I dyno'd low but ran faster on the street then others that dyno'd higher. Weird.

I ran my STi at 22 PSI on the street and 30 PSI on race gas (with GT30R .82AR), and it burned less oil than my N/A M3.

Two thou-

No.

Different blocks, different applications, yada yada yada...Make a power goal for yourself and build towards that. You want good power and torque?

Exactly....Most Applications in the works for the Z will be in the 6-10psi area and punch you up 100hp (or more).

I work with Audi turbos all the time that will hold a steady 22-23psi, but that's a block that was originally designed as a diesel.

Every block has certain limitations to say nothing of the rods and bottom end.. Don't use PSI as the be all/end all

Not to mention the VQ has an aluminum block. Although I think even the EVOs are aluminum now, which is just amazing considering the boost levels involved.
