Gents I will be finished with my VT2 kit on Friday.
Instead of the 100mm pulley which boosts 5,5psi,
Roman supplied a 95mm pulley good for 6,5-7psi at sea level.

Based on the calculated loss of 0,17 bar or 2,46psi at 5000 ft, I would be safe to assume that my boost pressure will be between 4,0-4,5psi.

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
