    turbo chatter??

    im sure this topic has been up on here before but im just wondering is it normal to have this ?? ive blanked the old oe dump valve off by using a one way valve pointing towards the turbo,but havent t pieced it into the fpr. and ive t pieced my bailey d.v into the fpr.it also has an induction kit on so it sounds really loud when pulling off.the rear bcs is still plugged in with no hoses going into it.could this beharming the turbo at all?

    Does it chatter without the one way valve?

    It all depends on who you speak to as to weither or not it damages the turbo. But imo its not a good thing.

    all this talk about its bad for your turbo is rubbish.
    ive been running an open cone filter and no dump valves what so ever for nearly a year now at 288bhp i havent had a turbo related problem once.
    the only diff i notice compared to having re-circ connected was that now it is a bit more laggy and takes longer to spool up between gears.

    but for the noise you get, its worth living with the lag!!!

    Thats the boost going back into the turbo blades, stalling the turbo. Thats definatly realllllly good for your turbo!!

    My coupe has always chattered on phase 2, doesn't worry me, plus the 'it's harming your turbo' buisness is all a load of hype. ZET & LEH turbo's are tiny and not running a large amount of boost so it wont do any damage. And if you want to hear chatter more, put on a cone filter/induction kit and block off the OEM dump valve

    surely the turbo spinning against locked in pressure and stalling cant be good for it can it.....? thats part of the reason why we have recirc and dump valves in the first place right.... also you want the turbo to keep spinning inbetween gear changes, if its chattering its not staying fully spooled up and ur gonna get lag.......
