Re: REFLECTOR: Reflector:SVX & IVO Prop update
I'm using an arimid belt type PSRU built by Don Parham RFI with a 2-1
reduction. This gives me an offset of just about 4 1/2" because of where I
mounted the engine on the firewall. I have 12 1/2" ground clearance and my
prop is 1 1/2" closer to the firewall than standard. My cowl is modified to
come together to a "boat tail" at the aft end to be shorter and to
allow my exhaust augmentors to work.
The bilge fans are plumbed to the heater core which is mounted on the
firewall, engine side , one draws air out of the cabin thru the core and dumped
overboard (not exhausted into engine compartment*) the other draws outside air
thru the same scoop that cools the main radiator and feeds the engine and either
feeds it thru the heater core and into the cabin for cabin heat or bypasses the
core for cool air into the cabin.
My engine RPMs are as follows peak torque 4800 RPM, max. HP 5600 RPM,
redline 6000 RPM and as I said my PSRU is 2-1 so my prop speeds are 1/2 that.
Subaru lists that engine at 230 HP in the car, Ivo says it must be making more
than that based on how fast it turned the "standard pitch" prop. I've
made slight modifications to the air intake system and a less restrictive
exhaust manifold otherwise the engine is stock. Hope this helps.
