What fuel pressure do our cars run at? I have heard through the grape vine they are roughly 68-69psi, but after putting in my SW FPG I am seeing around 48-50 at most at WOT under heavy load. What have you guys seen? Oh by the way I'm new here, welcome. MECP First Class installer on board now for all your electronic needs. Woohoo.

Come on people.

 

Fuel pressure is steady at 60 PSI under idle or WOT.

 

How much horsepower can the stock fuel pump handle? I have the 2.4L VVT Engine.
Are they the same pump as in the SS/SC cars? I am planning on installing a turbo and am not sure how to upgrade the returnless fuel system. Hoping stock pump will be good enough.

FYI- The official acceptable range specification (from the Fuel System Diagnosis in the FSM) is 50-60 psi (345-414 kPa )

11,000,000,000.3 Psi

 

GM said that the stock fule lines where good for 600Hp and the pump to about 450hp.
