This being my first turbo'd car I thought I'll ask for some guidance first.
I didn't buy it to start turn boost up full, my n75 is faulty and tbh it looks better in the bay!
Has anyone got a diagram of how it's fitted?
Carnt seem to find anything.
Thanks
 
you will lose part throttle drivability with an MBC and potentially upset the ECU into limp mode...

I see, I didn't think it would have a knock on effect like that!
 
I used to run one in parallel to the N75 years ago to cap boost spikes inherent from mapping big turbos stuff above MAP sensor limit... part throttle stuff was awful in all honesty...

Much better boost control mapping techniques available these days so N75 all the way

...technically limp mode would be a problem too as the ECU would have cut N75 duty to prevent damage from excessive boost

<tuffty/>
 
Right I see, I'll shop around for a new n75 instead then!
Thanks for advice!
 
Go direct from a dealer, much like MAF/coilpacks etc :)
 
That's the wrong MBC anyway.. you need a ball and spring version...
