Turbo Fault?

Hi

 

I have been reading posts here regarding turbo operation

 

Mine however doesn't respond the same.

It is twin turbo but my boost doesn't hit till around 4k and the sits at 0.8bar and stays there

no hesitation or anything pulls right to the redline.

 

I decided to investigate and have found a nut with a wind in grub screw at what I belive to be the arm

that activates the 2nd turbo.

It looks like it is holding the arm open as it cannot go back as against the grub screw.

Would this be to run the turbos inline?

Can it harm the car?

Would it be better for me to take this off?

 

Advice needed as everything else hoses inc look right.

Many thanks.

Jay

Anyone?

 

After a bit more digging it does seem that it is holding the exhaust valve open, I am presuming that this is a inline setup

The car responds as it should so I will leave it for now

I am putting on a Boost controller soon so it may help.

I will take that as a no lol

 

I have investigated Google and it is a parallel conversion

Looks like a good job done

I think when I fit the avcr it may come into its own
