There have been LS based V-16s built. Caddie had one in a show car: 1000hp.Hmmm, that Fiat AS.6 with uncoupled crankshafts isn't what I am doing, but might be an option for Reno racing. It probably isn't practical to direct couple crankshaft together that long because of torsional vibration.
Somehow I get the feeling thin tapered swept wing would still be the thing.
NXT with a LS based V-8, turbo'd to an easily achievable and reliable 1500 HP. That should carry the Gold for a year or two
2 big block aluminum V8's in the DO-335 configuration. Steel tube fuselage, composite flying surfaces. Gear retracts into fuselage.
Also in the case of Vought XF5U-1 ?Twins present more wetted area and interference drag. Two engines are more expensive.
4 is a good number. With fairly low budget you could build 2 double twin engine with contra rotating props like in Macchi MC-72, but smaller set ups.
Known issues on Glasairs: interference drag at the horizontal and vertical stabilizers, exposed aileron counterweights when ailerons are deflected, cooling air drag around the very crowded front LG assembly, NACA FI air intake not optimum, reverse airflow into the tail cone around the rudder and elevator actuators, oil cooling air flow drag, wing root LE. I’m confident that there are others.I'm thinking an all carbon Glasair 3 with some wind tunnel testing to find the little bits of parasite drag to reduce.
But you could make a 6 000 hp twin engine racer with less wetted drag than a P-51D.If that were a real airplane that could fly, the induced drag in pylon racing would be very high.
