When did he say that? Quote him. I dare you. Your timing should be set
up at 10 degrees (if it does indeed have a renault dizzy). Setting it up
at 13 at idle may well lose you power because that dizzy is meant for
10. Renault and VOlvo Dizzy's are different to the DeLorean dizzy which
is specific to the DeLorean. I can't say it simpler than that.

No, that isn't what he said. Quote him.

And my 2 litre Citroen diesel engine produces 185 ft-lb of torque yet
kicks out "only" 110hp. Haven't I said before that big american lumps
are just wannabe diesels? That's 92.5 ft.lbs/litre in mine. 460ci is
7.5l so your engine puts out 57ft.lbs/litre. I towed my project delorean
550 miles from Germany on a heavy trailer with that 2 litre engine.

So does my citroen. And it does 50+mpg.

If the cost of fuel or environmental damage are nonexistent. Then you
have no reason to innovate and you can sack all your R+D people.

Bollocks. Design an engine that's meant to be revved hard and it'll
suffer if it isn't. Ask any Porsche or other HIGH PERFORMANCE car owner.

Leaving a car to sit for ages without running will bugger them up much
faster.

Go and buy a lego car then.

Did it occur to you that the reason the DeLorean runs more advance at
idle is because it's at idle that the emissions are tested?
