• How much PSI without blowing the engine? by Bojje on 12 Jul, 2007 11:18
• Hello!
  
  As the topic says I'd like to know how much boost the engine can take safely. The engine: 1,9TD.
  
  Thanks

• Is your engine stock, or does it have modifications?  There can be a very big difference depending on your answer.

• i wouldnt push more than 20-25 psi if its stock
  if you put in head studs,it helps
  i used to let my old 1.6td go to 40 psi with studs
  its not really the boost that will "blow it up",its the amount of fuel
  i used to go 40 psi with the stock 9mm inj. pump,but when i did it with the 12mm pump i installed later on ,i started popping head gaskets

• Sounds like Brighten Torque...........
  
  "Torque it up untill it breaks, ....  Then back it off a 1/4 turn..."  :roll:
  
  After replacing all the "used a bigger hammer, becaused it didn't work anyway' stuff, back the boost down a 1/4 psi.
  
  you will find the perfit match between your walet and your need for........"OMG...What have I done?......"
  
  Enjoy!   :twisted:
