Surprisingly the engine was used in the BV 222 a six engine flying boat.
    That engine was designed for aircraft use, and designed to produce those 868 horsepower for hours on end. A chipped diesel for some guy's hotrodded pickup truck needs to produce those horsepower for a few minutes or seconds at a time. Unless the internal structures of the engine are considerably beefed up, it won't last long enough for any kind of aircraft use outside of air racing.

    The Russian M14P radial would give you decent weight and about 360hp plus better scale looks and sounds than a turbo diesel.

    If you're stuck on a diesel, the only one I would consider is the V8 EPS one which should be certified this year, unfortunately, I'd guess it will be around $100K.

    I can't speak for the large displacement diesels, but I've been doing my best to keep a close eye on Honda's new(er) i-DTEC 1.6L diesel.

    It looks to develop ~118HP @ 4,000 rpm, and ~220lb/ft of torque @2,000 rpm.

    I haven't been able to track down a weight figure, only that the engine "weighs 47kg less than their equivalent 2.2L diesel".

    Assuming the weight figure is good, I think this engine is something to keep an eye on.

    Honda diesel! It wasn't that many years ago that they said they would only make gas engines for cars...

    People have looked into this hard via process of elimination comparing quite a number of models and spec levels (Civic, Accord and CRV) that run the 2.2 Vs know engine weights for the gasoline range.

    It's figured from this that the 2.2 diesel weighs between 230 to 240 kgs (520lbs) which makes the 1.6 a boat anchor still.

    Re: 7.3l Powerstroke powered airplane

    I tuned in to say I own and drive a 6.9 diesel in my ford and it is a very heavy engine and at times can be a nightmare to keep running. In my opinion the goal for a diesel is to have a engine that runs wide open in the 2300-3300 rpm range to satisfy the prop need's and no PRU is needed. I think if a person can find a 3 cyl diesel producing 70 hp on take off and kept around 195 lb. total weight it would be good for the HBA community. By the way the 6.9 is the same as the 7.3 other then bore and stroke, can't tell the difference by looking at them. Name:  6.9 diesel.jpg

    Mercedes smart diesel is rated at 54bhp and I've seen weights of 65kg and 80kg for it.

    The fw-190s that attacked US bombers were dragging 30mm cannons around. They were the best fighter around when introduced with mere 20mm cannons. The British were not happy.
