Luckily, no VQ37VHR block has failed yet from boost (that I've known of) so one can't really tell yet the actual limit. But again, there are short term & long term stresses which can cause failures to the block. Yes, crank up the boost on the dyno to even say 700whp your block might not go airborne, but take a 500whp tune and live on the track for sometime and you will kiss it goodbye. GTM said you should be safe with a stage 1 on a stock block (500whp almost) but only time can verify that.
Funny how a TT'd 350Z (in Dubai) brags about pushing 500 ponies to the wheels calls himself the stock block killer when he doesn't even know what his car sounds like at 5k rpm lol
