Short answer: BAD...

Don't do it!!

BOV is there for a reason. To allow the pressurised air to NOT hit back onto the turbo compressor wheel. Over time it may cause damage to the fins.

Why on earth would you want the "flutter sound" anyway?? I hope it’s not to sound "cool" :banana:

Lol, this topic again?

50% of the world will say its bad, the other 50% will say it isnt. Personally i think it sounds awesome, but at the same time i fully agree with Adam, i dont see how it cant be bad for the turbo. Its compressor surge, spinning the turbine backwards, it can not be good. If you didnt need a BOV, why would anyone have them?

The sound of flutter/dose is awesome. Love it.

It will kill a ceramic turbo like stock R32, R33, R34, S13-S15 turbo's. Won't kill steel turbo's like single VG30 turbo's or RB30ET turbo's.

Flutter at 10psi is ok, but if you are running 14+ psi through a RB20/25 turbo it will kill the turbo

Dosing/flutter is THE BEST SOUND !!!

Flutter will not kill turbos.

Flutter DOES NOT CAUSE THE TURBO TO SPIN BACKWARDS.

Excessive heat (caused by overboosting or restrictions) will kill stock ceramic turbine wheels or nylon compressor wheels.

THANK YOU!

farken hell...

I blocked off my BOV ages ago as it was leaking and I kept it like that as it sounds better then an atmo bov and is still legal...

Boost (on standard turbo (presumadely)) is now at 1 bar and it's been like that for a while... turbo still isn't dead.

Either way, overheating and general miscare of the turbo will destroy, fluttering can be a part of this but not a main part...

    • New R34 owned here (from the US) and found a gem, '98 GTT with ~6k miles, super clean & completely stock. When shifting there's no grinding, shifts smooth, etc. The concern I have are 2 things: 1) Only in 2nd and 3rd... when maintaining a slower speed (in traffic as an example) as I let off/on the gas, the shifter will slightly move and vibrate. If the clutch is engaged, none of this happens. It's not bad, but enough to feel like something isn't necessarily right. 2) This mainly happen in 4th or 5th... the shifter slightly bounces up and down, almost like it's riding on unbalanced tires (and I do think the tires are unbalanced as I get a little of that bounce feel at higher speeds, which is maybe why it only happens in 4th/5th). Lastly, and sorry for this noob question but I want to work on this car myself, can someone teach me some on these manual transmissions? Like servicing them, best products to use, etc.; would be greatly appreciated. Thanks!!
    • Coilovers aren't even the first step. Bushes, subframe position and alignment, HICAS elimination, adjustable upper arms and traction arms in order to dial out understeer. All these things need/deserve attention first. ARBs (There's no such thing as a swaybar. Please, everybody, stop calling them that) are useful if you want to limit spring stiffness. Otherwise you can control body roll with springs. Spring and damper rates are a function of road surface, speed and usage. There is no solution that works for all cases.
    • Define "nothing". Is the starter spinning but not the engine? Engine turning but not firing? If the engine is turning but not firing, then you are missing either fuel or spark. You need to find whichever has gone missing.
    • Shitbox Tiguan updates, got the APR OTS tune put back on (no charge for it to be removed/added back), didn't want to just come in just for that (not a fan of wasting people's time for nothing) so I purchased an APR dog bone insert. The boys at German Performance Garage said they would fit it for free too since they had 1x hoist free. Now that's service you don't normally get from most workshops. Anyhow, tune back on, snow grate pulled out, dog bone insert back in and not going to lie, a few smiles when I nailed it around the industrial area heading back onto the M7. Amayama also said 1 to 2.5 month wait for the RB25DE heater hose, yeah why not, car has been off the road for nearly 3, what's a other 2.5?
    • Hmm I'm going to approach this from the other side... What is the car doing that you don't like or what would you like the car to do that is currently isn't doing (handling wise that is)
