Plz Help Flutter Noise

[KnightRiderR33]

Hey guys i need help with this recently i bought a boost gauge for my r33gtst ive had some issues hooking it up and people mentioned i should changed the vacume hosses so i did as well as the T piece i got hosses that were smaller then the ones already on the car.. Ever since the change ive been getting this flutter noise comeing from the pod filter.

1 reason i decided to change the hosses were that the nozzle for my boost gauge was to small to fit the hosses so i thought id change the T piece and the hosses to smaller items now ive herd rumours that this noise is bad for the turbine.

I know people r going to say change the hosses and thats what ill do but i want to know the correct size to use. MY BOV isnt stock well not stock for an r33 its got a mitsubishi emblem on it so im guessing its from an evo.

Thanks for all the help guys im new to the turbo scene and quite frankly i wana go the right path even if it means getting rid of that cool noise id rather run safe and smart rather then look like some show off who is about to take out a loan to repair his engine

So does this mean my skyline was a rare build partnered by mitsubishi?

I'm not sure hey

there are a suprising amount of mitsubishi parts on a lot of cars. it doesn't mean the cars were made by mitsubishi, just some of the parts were. the mitsubishi bov is nothing rare. pretty sure a wrx i put a front mount and new bov on had one as well. and i had a festiva that had a mitsubishi made throttle body on it.

as for the flutter, did you change the vaccum line that runs from the bov to the plenum? if yes, that is more than likely the cause of the flutter. if you went to a skinnier hose then it isn't able to suck the air out of the bov quick enough to allow it to open fast enough.
