maximum pressure of turbo in Mini Metro
Turbo Mini Forums

Hello:

I want to ask about the maximum pressure of turbo in Mini Metro. I don't know the opening pressure of the valve.
I'm do a project and I need to know what is the maximum pressure that receives the piston for calculate the impact (kg-force) in the piston.

Thank for all and excuse my poor english.

The car in standard trim, the Metro Turbo could produce upto 10psi of boost.
Again that is for an unmodified Metro Turbo

Thanks

I thought standard boost was upto 7psi?

i'll let someone else give a full explanation, but boost pressure is only a tiny tiny part of it.

and yes a metro turbo on full boost above roughly 3500rpm was 7psi, below that, 4psi

He asked for the maximum and I stand by that figure. Most often than not the little box of tricks would allow the Turbo to deliver 7psi but some cars were more equal than others and as standard some produced 10psi of boost.

It's ok for me. It's a reference for my calculations

I've never heard of any metro turbo making 10 psi on the standard setup. You have to ring the neck of mine to get it to 7 psi, as it only gets there above 6000rpm.
