Does anyone know how much boost (MAXIMUM) a non-modified CT26 turbo can handle???

sorta off topic but since we're talking about boost limit i just wunna ask if anyone knows the injectors duty cycle at 10psi? reason i ask is cuz over at the alltrac forums ive read on a recent topic that at 10psi the injectors are at 100% duty cycle which is bad (over a long period of time). can anyone confirm this? i tried looking at mr2oc and didnt really come across what i wanted to know.
even if it was at 100% at 10psi, alot of mr2t/alltrac owners have been boosting as high as 15 without prob over the years so i dont think this should be a prob...but im just curious  bboy --------------------  ..(formerly daily driven) 3S-GTE powered celica currently set @ 12psi.. |

ATS sells a bored out stock version for 75 bucks. The stock fuel rail starts to restrict the fuel after a certain PSI of boost. You are correct running over 10 PSI for a long period of time will cause major damage. --------------------  I will return one day. |
