Like what others have said, 12psi is the absolute maximum for a stock gtt turbo if you want it to last. That would also depend on your driving style, if you side step the clutch on a hot day it would most certainly shatter itself.

You could set up your Profec B2 into two boost levels, 12psi on HI for daily driving and 10psi on LO for track days.

so i guess 14 is out of the question!!!!! i might just have to do a hi flow and ecu.

need more power the car is only making 244hp at the wheels i would like 300hp

how do you figure that?

the shock through the drivetrain causes it to shatter does it? lmao

No, because when someone side step the clutch what usually follows is hard abusive driving ie fast gear changes, full revs each gear which means extra load and heat on the engine, turbo, drivetrain & etc. In which case the plastic/ceramic wheeled turbo would usually fail first before anything else.

Never as simply as "the shock through the drivetrain causes it to shatter does it?" :D if one doesn't have anything intelligent or valuable to say in this section, he should keep himself in The Wasteland together with his smart ass comments. LMAO

spot on the money mate. my turbo blew when i dropped the clutch on 13 psi. was a warmish day.

    • You're confusing two different responders and more than one issue. The stock Neo ECU boost sensor is used by the ECU for protection purposes. It is essentially only an overboost sensor. It is not used for determining engine load for fuelling or ignition purposes. That task falls solely to the AFM. Any aftermarket ECU that either has an onboard MAP sensor or a plug in one, will use the MAP sensor as the primary load sensor. Or I should perhaps say "can", rather than "will", because some of them have the option of using other primary load sensors. That MAP sensor is not for the same function as the stock Neo boost sensor. The reason I recommended against a plug and play ECU is that they are intended to run a particular engine and usually in the car that the particular engine came in. So, if you have a transplanted engine in a different car, with some parts of the original missing (such as the boost sensor, for example) and therefore likely non-standardness of the loom and its insertion into the car's loom, then it is very likely that you will run into the same problems with needing to fix up wiring to make it work that you would with the stock ECU. And, if doing so for the stock ECU is enough of an obstacle that you start considering a standalone plugin as a solution, it should become clear that the plugin is quite possibly not the solution you'd hope it to be. It would just lead to more of the same type of problem solving work to get it going. In the above paragraph and in my earlier post, the lack of the boost sensor is not critical. It was just used as an example of something that we knew you did not have right, such that the stock ECU would not work. I took that as an indicator of a reasonable probability that there were other related problems hiding there.
    • I can think of two places in my city of <1.5million population that specialise in automotive instrument repairs.Unless you're out in the wilds of Quebec, you have 3 major Canadian and 3 major US cities within the same distance as the single nearest city to mine. Surely there is somewhere you could send it.
    • I never cared for twins but whenever these conversations came up, I always presumed the higher number represented a larger turbo. Learn something new everyday. 
    • Interesting, I've never seen a failure like that before but with the age of these cars and the general questionable-ness of all kinds of parts these days you can't rule anything out I suppose. Boost leak testing the boost control system would've revealed this though.
    • Thanks for updating the outcome; while anywhere in the system could leak, I hadn't heard of a wastegate actuator doing so before, can add that to the list of potentials for next time
