If it's closer to 4psi after dyno, we may contemplate a 92mm Which is normally a 7,5psi pulley at sea level.
92mm is the smallest pulley you can use with the VT blowers without changing belts and software.
Practical will be better than this speculation  |
Your drop will be the difference between barometric pressures. At 5000ft you should only loose .15 bar or approx 2psi. I know this from trial and error.
