Orma, I think you are dividing the #s and should multiply instead. 4.99"hg X .491159 = 2.45psi. be careful 15psi boost (30.54"hg) manifold pressure of 60" could destroy your engine VERY quickly (seconds). I would try to keep manifold pressure under 40" (approx. 5psi) at all times. Turbo normalizing may be what you are looking to accomplish. i.e. 30" manifold pressure at 10,000'. However the engine would think its at sea level, the prop would unload and rpms would increase dramatically without a constant speed prop, not really feasible option with a vw.
