I was driving the car today, put it into high boost (340bhp, which I've only done a small handful of times, usually drive in the 280bhp boost map) to overtake a car in 3rd, put it into 4th and missed 5th and put it back into 3rd doing 90-100mph. Now I'm getting a strange rattle only on throttle above 2k rpm, boosts fine in 1st, have t tested 2nd but 3rd and 4th only seem to go to around 10psi. Engine oil seems clean on the dipstick, going to drop the oil tomorrow night just to make sure. Any ideas what it could be? The car is a 2005 WRX with a vf35 turbo, standard recirc valve.
Thanks for any help

If you put the car in neutral, check if the rattle change when you press the clutch, if so you might have stuffed the release bearing... Other than that, rattles are normally exhaust, exhaust heat shield, turbo heat shield or turbo itself.

this above 2k noise part, is it around 2600 rpm to around 3400 rpm ?
does the noise go above those revs ?
