Exactly. Specially an engine this big. I?m also impressed that it revs to 8.000 rpm. :shock:DarkReaper said:Low Hp/L?
It has more horsepower per litre than the Pagani Zonda F.
At 85HP/l is very impressive for a naturally aspirated engine.

"only" 1100HP? "ONLY" 1100HP?!?!? Are you serious?

So you're saying that having more HP/L than a Zonda F (as useless as that figure is) is somehow unimpressive? They're both N/A, what's your point? A lousy excuse for what? What the hell are you talking about?
BerserkerCatSplat said:vanMould said:I'd expect about 2500hp from and engine that size. Supercharged of course, but still...
Let's have a quick, very basic lesson in Engine Building 101, shall we?
1) An engine's internals can only handle so much power output. There are 2 types of engine stresses - torque output and RPM. Torque is the base power developed, and RPM is how often that torque is "created" by the reciprocating assembly.
2) It makes little to no difference to the engine's internals whether the engine is N/A or FI, short of the compression ratio usually being lower on an FI motor. A block built for 1300 lb-ft will hold up to 1300lb-ft, whether it's N/A or FI.
3) 2500HP out of a supercharged 13L engine is pretty much impossible to do reliably. Once you hit around the 2000HP mark, you need to rebuild your engine every 1000 or so miles if you drive like a grandmother, and every 50-100 of you flog it. Metals able to withstand that kind of power just don't exist yet. (Or they don't exist for non-ridiculous prices)
Thus, your idea that any 13L engine should be making 2500HP supercharged is rather stupid and demonstrates that you really don't know what you're talking about. This is an impressive engine. End of discussion.
vanMould said:So nope, you still haven't convinced me that 85hp/l is a job well done...
Nelis said:It actually is for this size engine. Look at the torque it makes. A normal v8 would never be able to hit that amount of Trq without a supercharger or the same engine size and still be reliable. Like Berserker said, it's not the amount of power but how long je can actually sustain that amount of power with the materials used. It's no use having 2500hp when you can't put it on the road propperly or when you nedd to rebuild the engine every 100 miles or so. People would just never buy such a vehicle.
BerserkerCatSplat said:vanMould said:So nope, you still haven't convinced me that 85hp/l is a job well done...
Please explain to me why on earth you think HP/L is somehow important, especially in a case such as this.
to get a 12.9L v8 to rev to 8000 rpm and make 1100 hp is insane, period. big engine without a lot of cylinders just want to make torque, they dont want to rev or to make any hp. you also have to remember that it is a lot easier to make a more reliable motor if it has more cylinders for the same reason as a bigger engine, the distribution of all the stress.BerserkerCatSplat said:vanMould said:So nope, you still haven't convinced me that 85hp/l is a job well done...

Fun Fact: The more displacement an engine has, the easier it is to make it reliable at high HP/torque numbers, as engine stress is more widely distributed.

Jeremy Clarkson barely knows how an internal combustion engine works, forget being impressed by the "engineering." Seriously, he's stated many times that he has no idea how cars work, really. Jeremy Clarkson enjoys making fun of American cars, and that's the only time you'll hear him making fun of displacement.
BerserkerCatSplat said:And calling this engine "unsophisticated" is rather uninformed. Do you have any idea how hard it is to get a large-displacement V8 to rev to 8000RPM without breaking stuff? It's damned near impossible! The precision engineering that must have gone into this engine is truly staggering! Sure, it still uses pushrods and carburetors, but that's mainly because a fuel-injected DOHC V8 with that kind of displacement would never fit in an AC Cobra engine bay! They did what they needed to do with what they had to work with - and I think that's more impressive than having no limitations on engine design at all. Weineck has created earth-shattering power from an engine small and simple enough to fit in a Cobra shell.
vanMould said:But back on topic: your arguments for using a pushrod engine with carburettors is basicly to keep the bonnet sleek? Well...they sure managed that, didn't they?
I find it wierd to build an engine to be as powerful as possible while sticking to limits that they've made up themselves, instead of building an engine as powerful as possible over all. Keeping the height down is a weak argument imo, especially if you stick a monsterous scope to it afterwards.
vanMould said:Are you sure that the Zonda is N/A btw? I'm dunno myself, but I think it sounds wierd to lift an engine from Mercedes with AMG badges and everything, and then remove the supercharger...

To me, that?s proof enough that you have no idea about cars and engineering.
