just as the title says i have a flutter type noise buggered if i know where from... but i will try an explain
as soon as the car hits about 5000 rpm - 6500 then i have this very loud flutter noise it sounds like the blow off valve is realsing presure but its not had it on the dyno and looked, when it starts to fluter as u could imagine the power band is spiking up and down its not good for the motor. has anyone had any problems like this what was it how was it fixed? sorry to be so vauge but i cant think of anythink else.
the motor is 3sgte mr2
ct26 high flowed...
also i know its no boost leak through any of the piping because its not a constant hissing noise its a flutter!?
