Turbo installs n stuff

This is a place to put all my stupid turbo questions.
Is a BOV the same thing as a wastegate?
Hopefully the questions will get less tupid with time.

grazie.

I believe not dude. A wastegate bleeds the exhaust gases to bypass the rubo, when the inlet boost pressure reaches a certain threshold. A BOV releases the pressure in the inlet tract when the throttle closes to stop the trubo stalling, and causeing undue damage.

I think that's right

Ok.
So essential part of any turbo install then?
Do you see the on all turbo cars?

Wastegates control the target boost pressure and BOVs get rid of the boost you don't want.

You won't see a BOV on an OE car, they all use recirc valves.

ok,well as you can tell your speaking to a turbo noob here.
Is it common for DIY'ers to omit them too?
Do you run one?


I guess what I'm asking is will I need one.

Thnks.

Diverter valve or BOV, tis up to you, but you will need either

Yeah it depends on setup and personal preference Some folk love the pshhhhht noise of a BOV and will always go that way, and others prefer the silence of a recirc when changing gear.

The other thing to consider is flow. If you've got a largeish turbo that flows lots, you'll be wanting to get rid of the unwanted boost very quickly, so a big flowing BOV will be required, such as the Tial 50mm, or for recircing, Forge do a big valve and Tial have their new "bong"

Yeah, I use a BOV... the Tial 50mm job.

That's a coolant connection isn't it?

yup,for the turbo obviously.



Don't know what people usually use..

On the VRT you just use the throttle body coolant hoses

I have seen a VRT take water from the back of the block using one of those core plugs though. It's a very neat way to do it!

I guess that is for the water return, rather than supply?

Thats coolant feed.
