The spring is 1.2 bar and runs this when connected straight to wastegate.
The manifold is fine as i modded it being a xs one. Also i have been driving the car for 2 mths with low boost set at 1.1 bar and high at 1.35 bar and achieved this consistently.
I think i was getting 1.1 bar as boost was leaking from the manifold gasket, but as soon as gasket sealed leak the boost went up to 1.2 bar.
I played around with the greddy bov today, and tried loosening the screw and the boost dropped to 1.23 bar from 1.28 bar.
I then tightened the screw as far as it could go and achieved a max of 1.32 bar.
1,Has any of u guys had any problems with ur bov on single turbos?
2, What bov are u using at what boost pressure?
I was thinking hks racing 2 but think it might not work properly at my boost as the spring might be too stiff.
