Look at the power and torque figures, if the car was producing 1298lbft at 5600rpm then the power would be: 1298*5600/5252 = 1384hp which is 284 more than the peak claim and 1400rpm lower down. There is no way an NA engine can produce 100lbft/litre on regular fuel anyway. The power might be right but the torque can't be any more than about 1025lbft
It makes between 1100 and 1200 NA. Between 1300 and 1500 with nitrous oxide injection. Now, imagine the possibilities with a block this strong and high revving. Forced induction, say 18-20 psi, and intercooled. Then, an ultralightweight aerodynamic body. What I'm basically saying is, imagine the supercar that could be built around this engine.
I know for a fact it does do 1100-1200 NA, and 1300 with nitrous injection. I am not certain of the 1500 figure, I only heard that on a forum.
There is no way it generates 1300 lbs/ft of torque from a N/A 12.6L engine. Thats more that 100lbs per liter, which is only possible from forced induction engines. Even the engine from the Enzo (and I hope people don't think that Weineck can build a better engine than Ferrari) only makes 485 lbs/ft from 6 liters. That works out to about 81 lbs per liter. Maybe I'm wrong, but if I am, someone tell me what other car in the world makes 100 lbs per liter. I bet you can't.
im pretty sure its supercharged, i remember reading that somewhere edit: it doesnt look that way in the photos though, but im really damn sure i read it was supercharged somewhere back when it just came out bleh im probly thinking of an other cobra
in response to TheCarGods comment about a there not being a naturally aspiratred engine is mass production that doesn't make 100hp/liter...ever hear of a little two seater car called the Honda S2000. According to the Honda the engine makes 237 horsepower at 7800 RPM and 162 lb.-ft of torque. All of this out of a 2.2 liter 4 cylinder. Let's do the math, 237 hp divided by 2.2 liters is 107.7 hp/liter, unless i'm mistaken.
The one I meant is an older version, I think "only" eight litres or so. It had a nitro. Those times they were talking about the possibility of creating a 13 litre version... Considering that 1/2 litre per cylinder is supposed to be optimal, I wonder how they manage to distribute the gas effectively to the chamber. I guess it is still far from perfect and that engine could develop much more power if they keep on working on it. Btw, notice the 4-gear manual, I think it is a Nascar gearbox, anything else would be ripped apart by the monstrous torque.
I think the HP and torque figures may have been switched. 1100 lb-ft at 5600rpm sounds about right for 1300 hp @ 7000rpm. That mean it makes 975 lb-ft at 7000rpm. 975 * 7000 / 5252 = 1299.5
i was thiking that too, maybe it produced 1300hp at 7000rpm and 1100lbft at 5600rpm - that would be feasible
This engine has a HUGE capacity for improvement. Because it is huge. A V8 this goddamn big does nothing for me. I want my 854 cui V16. Think, 200hp per liter is feasible... 200*13=2600...
That works out to around 86 horsepower per liter. Seeing as horsepower is a function of torque and engine RPM that is pretty damn impressive. Obviously it has torque in spades, and why not, it's friggin' huge. Being able to rev as high as it does though, that's something to wonder at. Each piston in this thing is gi-normous, and it has to come to a complete stop and reverse position every cycle. This is why your high hp/L naturally aspirated engines tend to be smaller, since it's less rotational mass to stop and start. Obviously if money isnt an object, you can build high displacement Carrera GT and Enzo engines, but these are the exceptions to the rule. So is it in the 100 hp/L club? No. But it's still a damn fine piece of machinery.
No matter what that thing would be a wheel spin machine. I bet 100mph roll-on burnouts are common place.
Wow and to think that a 12.8 liter V8 could reach 8,000 Rpm!! Anyways, in theory yes the engine should be making more power, however we forget that this formula only works in 'perfect testing conditions'. In real life the engine suffers from friction, has to power other things like the battery, and loses horsepower do to heat and atmosferic pressure and other factors
