But noise, then more noise, then more... within certain limits the harder you press the pedal the more power you get, but a diseasel is the opposite once it's off it's limited boost curve. The typical small bore sub 2 litre diesel is awful for pressing on, having to plan ahead, make sure you're in the right gear to keep it on boost, then running out past the boost halfway through the overtake. Turbos barely make diesels bearable, they don't make them awesome.

Haha, theres quite a few who would argue that point. I know your talking about sub 2 litre but who would buy a sub 2 litre and the same argument could be levelled at a sub 2 litre petrol motor, or certainly a large chunk of them without the turbo. A 3 litre twin turbo diesel will pin you back in the seat and will not run out of boost halfway through an overtake. Thats why ive bought so many over the years.

Au contrare. My olde 407 Coupe HDi was the Jag 2.7 twin turbo diesel, and it was meaty and the grunt was huge, but only for a very limited RPM range. The petrol v6 murdered it, and made litle difference with the fuel consumption because the petrol V6 didn't need it's neck wrung to go quickly.

Haha, times have changed. Not much would murder the current Jag, sorry.

Thing is if we're talking big panel vans like Mercedes etc you get the big super powered D units..

I've driven a couple of Ford 2.0litre diesels with auto boxes.

Both pull smoothly and well to far in excess of the speed limit.

Plenty of poke for overtaking.

I reckon @Drago is getting confused with the lumpy old tractor diesel in his pick-up.

Cant argue with that.

I think there's plenty that will squat it's buttocks over the current jag diesels.

There simply ain't no substitute for ignition advance, and diseasels just ain't got it.
I'm sure there is, but I'm just not running out of boost any time soon. Anyway, we can agree to disagree as the bells aren't far away. Happy new year when it comes.
 
[QUOTE 4619365, member: 9609"]not really relevant, but probably the madest production diesel was the Detroit V12, Two Stroke Diesel. I think they used to measure fuel consumption in gallons per mile. Often known as the screaming Ford, (it sounds very high revving but its not, 4x as many firings as a 6 pot four stroke) I think anyone driving this all day everyday would soon go insane, or deaf.

Pfft. Proper transport measure it in gallons per metre, or tonnes/day. I've worked on ships for best part of 30 years, which explains the mild tinnitus and insanity. Incidentally the big two strokes tend not to be that noisy as they operate quite slowly (65-95 rpm IME), it's the turbochargers that make the racket as they are at a higher frequency.
