Turbo Fluttering Noise

[ALF05T]

Gday all Im new to the forum. Some might have seen my red xr6t on the last cruise down the old putty road. My turbo seems to be making a fluttering noise between 3 and 4 grand especially noticable in 4, 5 and sixth gear. Ive been told that the power which my car is making is too much for the wastegate / actuator set up which is standard. Is this a common problem? My car makes 360rwkw. Any help on problem would be great.

Oh and as it looks like your first post.

Does the fluttering noise happen when you are under acceleration or when you back off?

[ROLMDL]

sounds very normal to me with that power

The problem only occurs under acceleration and is most prominant on hotter days. The mods I have done are exhaust, cai, injectors, valve springs, blow off, intercooler and clutch.

Also would this be doing damage to my engine / turbo?

sorry, did not see this before.... who tuned your car... with what?? (flash tuner/unichip).. have you got a dyno graph you can post up??

reason for asking is I have the same mods as you, I also have a manual, but cannot get anywhere near 360 rwkw.

thanks

same here.. although I also have a fuel pump, but I don't have the valve springs done yet, so that will be limiting my top end power.

Weird for the BOV to be making noise under acceleration??? possible boost leak somewhere in the system? mine makes a pretty gobble gobble noise when I back off. it's standard bov

Dont wont to go bad mouthing tuners I do have a paper coper of my dyno graph but no scanner. I thought it to be a bit high as nobody else has this power with the same mods.
