The P&W J58 is a complex engine, in relation everything is simple.

None of the tech involved in the Deltic engines is significantly more complicated than a standard engine, it's just designed differently.

Simple wasn't really the word I was looking for, regardless it's an ingenious design based upon principles already in existence.

Fisrt off before going gaga over horsepower numbers let's look at torque figures......pleaseeeeee 

Horsepower is great it is the motive force that keeps the mass moving along at whatever your chosen speed is. Tourque is what drives massive acceleration.

Lets pick on the theoretical toyota again if we had a motor developing 600hp and 1ft/lb tourque id would not burn up acceleration ramps it would inch it's way forwards..... eventually on a 200 mile long straight said toyaota could reach 180mph and it would have the horsepower to maintain that speed. Now invert those numbers and lets run the 1hp 600ft/lb of tourque theoretical toyota up the ramp it can reach 180mph in less than a mile but as soon as you quit accelerating it just keeps slowing down because your 1hp is barely enough to maintain forward momentum at 1/2 mph.

Ok I was just picking on scott, big horse power big tourque and low rotational mass these things excite me

Nice. I've never considered it that way. Excellent explanation. Bump.

Ooooops I wasn't making fun of scott's post.....

Yeah I was having some fun with your post ohgood

Glad you like the explanation, I know it's a bit simplistic but it's one of the esaiest ways to introduce the concepts of tourqe and horsepower to people.
