S8 Electric Vacuum Brake Boost

[skylion]

I'm running a big power GTR RB26/30 with big cam setup and large brakes. Brake pedal is solid as there isn't enough vacuum for the brake boost to work properly.

I'd like to address the issue with an Electric Vacuum Pump assist driven by a spare output on the Syvecs S8. Is there a strategy I can use to engage the pump when vacuum is below a set value?

Brake By Wire output and a Load Cell input maybe ?

Or just just find a cheap vac switch ?

Or delete the servo.

Or diesel alternator with vac pump ?
