So let me just play devils
advocate and throw this in here.
I designed my intake manifold to
be compact, lightweight, and fit into the cowl without any contusions or
bumps. I designed a compact tangential muffler, and a secondary muffler, for
light weight and suppression of the noise. No effort to ‘tune’ on either
end.
The result is that I get a very
flat torque curve, and about 90 HP per rotor at 6300, using the 9.7 turbo
rotors in a NA engine (actual dyno data). It is also one of the quietest
rotarys around and the exhaust system is still solid and sound after 180 hrs
of operation.
No; I’m not bragging – and I
don’t doubt that a few more HP could be squeezed out over a small rpm range
with tuning. The point is simply – how much time and effort do you want to put
into the misty netherland of tuning the intake and exhaust? Maybe focus
on lightweight and durable design.
Just a
thought,
