sounds ok?

So ever since i got the vf36 put in, you can here some whining noise coming from the turbo or something near it, im not sure if this is normal, maybe a exhaust leak or boost leak. or maybe this is just the way the vf36 sounds! It does seem a lot louder than my old twinscroll turbo!

Roller bearing turbo ?

VF36
(430 cfm, 250-325whp, Modification Required) This is the standard equipment turbocharger used on the JDM V8-V9 Subaru Impreza WRX STI Spec-C Type RA.
Roller bearing version of the twin scroll VF37, also has a titanium turbine and shaft for even quicker spool. Same compressor housing as VF30/34, however twin scroll P25 exhaust housing provides slightly better top end output due to reduced exhaust pulse interference. This turbo is good for 400HP and used on JDM STI Spec C from 2003 onwards. It is essentially a fast spooling VF34.

I wouldnt worry about it man
