J, a turbo is more thermally efficient, but there are
millions of factors involved. An Eaton MP45 comes
with a bypass on it, so you don't really use that gas
when you don't need it.(If you are me, you will be owning
Exxon) Also, a kit for a supercharger may end up costing
around $2600 rather than $3995. Also, the power from a
supercharger is linear. Since we aren't looking to get more
than 200 horses out of it, there are no huge benefits on the
turbo side. Albeit, there may be some but not for another grand
or two. You can easily get close to 200hp which is worth
$2k. To me at least; but $4k is pushing it. If you plan on going
over 200hp, I would suggest going with a turbo, also with
over 200hp, and either air crusher, I would suggest you
invest in some good forged pistons. As far as the reliability goes,
the hp levels we are going for are fine using either, but when you get
into more psi, you would want to go with a Turbo as a Turbo does not
kick in until you are higher in the rpm range you do not have to
worry about throwing a rod as much. The level of pressure we are
going for this will not be an issue. If we were to overdrive it and go for
more psi than we are planning, I would suggest some custom
H-Beam rods and some really good pistons. As far as what we
are planning, I don't think it would be necessary to even worry
about this stuff. We are only seeking around a 40% gain.
