Turbo Mini Forums

I introduced myself a few weeks regarding my supercharger project.
my next question is whether there'll be enough vacuum to support a dump valve and a remote brake servo. because i'm a old man with health issues a servo is quite important.

anybody?

There are plenty of turbo minis and Metros that have been built using an OEM vacuum servo unit and utilised a dump valve.
I can't see why it would be an issue provided everything is in good health.

many thanks, I wasn't sure.

I,m making slow progress. I fitted a rh tank a few years ago and I was wondering if I could plumb it in to the mpi tank. do I just connect it to the return pipe from the injectors. the rh tank is vented to the air.

As soon as you take your foot off the throttle there will be shed loads of vacuum in the inlet manifold. There is normally a non return valve on brake servos so there will always be vacuum assistance from the servo for at least one press of the brakes, even if you tried the odd combo of full throttle and foot on the brake.
