Boost by gear

[David-1dyf3]

Been trying to research as I'm not totally clued up with what is the minimum boost/ psi you can start to install a boost solenoid, to control boost by gear or rpm.
Or is there a page to direct me onto?

Currently got a tial 38mm MVS, 4.35 psi wastegate spring in seeing a maximum 9 psi of boost.
Looking to put a 5.80 psi spring in, would this enough to start looking at a boost solenoid.

Thanks.

I always thought the idea behind a solenoid was to manipulate the spring pressure as such you can run a wastegate pressure and then go up from there just by adjusting the duty cycle.

Seeing a maximum of 9psi, how so? is there anything controlling the boost now?

You can install a boost solenoid whenever you want....what you do with it is another matter

A page to direct you to what ?

And your last comment is odd...explain better what you want.

but boost by gear is easy with the correct controller, within any mechanical limitations there may be.
