Question Boost Question

I was wondering. When my boost gage reads 1.8 bar, what is the actual boost pressure? Thanks

of the dozen or so 951's i have personally checked the stock boost gauge on, every single one of them read spot-on accurately.

1.8bar on the stock gauge = .8bar of boost = 11.6psi

Thanks, what is happening when the guage reads .4 to 1.0?

That means you are running vacuum in the manifold which is normal.
