Hello to all from Athens GREECE.I have an 98 integra type r with jackson racing supercharger 3,8'' pulley ati cranck pulley(i think it is 5,5'').I saw at the lht site that doost is 9,3 psi (for b16a and sir cranck pulley)and 7,1 psi for integra gsr with the same setup.does displacement effect boost???

 

Displacement affects it the most, besides pulley size. The amount of overlap in the cams affects it too, but that is almost impossible to calculate. Overall V.E. of the engine counts too. Don't focus on an exact number, just try to get within a certain range.

 

thank you!I just wanted to know the boost because my engine has stock pistons and rods and i am afraid of high boost...
