hey everyone hows it going

i recently put a high-flowed throttle body in my car, its a great mod, heaps more low-down response(increase in torque?) , makes the car easier to drive in the lower revs,


anyways, driving home with the throttle-body on i heard a feint metallic whine whenever i pressed on the accellerator, which i thought was fine, as it could possibly just be the noise of the high-flowed throttle-body,

recently though, whenever i press on the throttle i hear the same feint metallic whine, which is now accompanied by a fairly audible whistle, it sounds like someone whistling or possibly like wind blowing over a leaf at high-speed,


has anyone experienced this before ? anyone know what could be wrong ?

all replies are appreciated


later :cool:

actually i worked out that the noise is coming from the fpr, anyone know anything about rising rate fpr's making weird whistling noises ?


later :cool:

Did you read Mitsiman's post at the end of your thread "fuel pressure regulators" :)
