Sam, As you find in this "hobby" there are always
trade offs. First, technically there is no reason you could not do what
you propose - however, you will add weight and complexity. A poor intake
affects both N/A and forced induction - its just with forced induction you are
paying in a different way to overcome any defficiencies in your
intake.
If going that route, I personally would prefer the
centrifugal type belt/gear driven blower over the roots type which has
historically had the poorest efficiency. On the other hand, if you are not
going to "boost" above ambient pressure - then I think I would concentrate
on getting a good N/A intake.
Good luck on your project whichever decision/approach you
take. Super and Turbo chargers have both been used
successfully.

Subject: [FlyRotary] Renesis Question
I think my brain has had a meltdown: I am thinking about
"supernormalizing" the Renesis engine. Is this even possible. The idea is to use
a by-passable positive displacement type blower (roots type...probably an eaton
m90) fed to an intercooler that then sends air to the engine. If my thinking is
correct, and it probably isn't, this would eliminate the complex N/A intake,
while not over-boosting the Renesis engine. Also, the supercharger being a
positive displacement blower would in theory produce more boost than is needed
by the engine at all rpm levels, eliminating the "peeky" torque of boosted
engines. The excess (above standard intake) pressure would be controlled via an
automatic or manual waste-gate. Please shoot my idea down if it is insane, but i
would like some constructive criticism if it is available.
Sam
