My really, really, really BIG engine
Since it is OK to raise our gross weight during certification, I've decided to install a Pratt and Whitney R-2800. I'm figuring it will be a little nose heavy, but if I put the batteries and the strobe power supply below the horizontal stabilizer, I will only need about 182 pounds of lead in the tail.
Since the magnetos and pressure carburetor are so out-dated, I'm going to install my Apple 2E in the right seat to control a capacitor discharge ignition
and electronic fuel injection I salvaged off a wrecked Subaru Outback. To save weight, I'm only using one spark plug per cylinder, and I've welded closed the other plug holes.
The fuel system is going to be a real challenge. Because the engine flows such large amounts of gas at 60 inches of manifold pressure (two stage blower) I am planning to adapt the 2 HP centifugal pump off my pool filter to pump the fuel. Going to use the diatomacious earth filter from the pool equipment to filter the fuel, thus saving space on the firewall by deleting the
ever-contentious gascolator. This pump is of course 220 volt AC so it will require a rather large static inverter, which I plan on installing in the baggage compartment.
This airplane is going to be really, really fast. Probably the fastest in the country. Range will be somewhat limited, but because there is no room for a passenger, I plan on installing an extra fuel tank in the right seat, under the
Apple computer/engine computer.
For those of you that will find fault with my installation because it is heavy, complex or inefficient, I want to remind you in advance, that this is "Experimental Aviation" and it is my right to build as I please.
