v/a = me needing more sleep. lol
Density relates the mass of a substance to its volume through the formula: D = M/V
(D)ensity = (M)ass / (V)olume
in non- technical terms, the "more" air you compress (via a turbo) into one place, the more air actually gets in per given space.
lager turbo's compress MORE air into the SAME space as smaller turbos, thus, increasing the actual amount of air avaible to combust.... and combustion when mixed with fuel and spark = power.
the problem is that you are trying to figure out a good psi to hit 300 hp.
psi should be the result...
or, it takes X psi on Y turbo to hit Z power
we have 1 variable filled in- Z
X * Y = 300
well, its nto really multiplication, but thats the best way to write it.
here's an example:
if you run Y as a to3/to4e, it will take, X psi.
if you go smaller, it will take X+5 psi
if you go bigger, it will take X- 5 psi
does that make sense?
