That is an 8L W16 Quad turbo engine. We're talking about a small, 2.4L Twin Turbo V6. I dont think your argument works to well...
Note: I have no doubt it could be done, just clarifying that yes, the Veyron SS is only 300hp shy, it also has 10 more cylinders and 2 more turbos to do it...
You do know that it's the rews that decides how much output you can get from an engine.... in combination with it's volume (Torque).
A NA engine produce close to 100 Nm (73,75 Lb.ft) / L engine volume.
An aspirated (Supercharger / Turbo) engine produce more, depending on how much pressure the unit and engine can take.
Tourqe x Rews = Power
An 8L W16 engine that produce 1200 bhp at 6000 rpm would produce at around 850 Lb.ft. 850 Lb.ft seems like an reasonable fighure keeping in mind that the engine got 4 turbos. (This is just made up fighures, but I'm sure they are close to the real life number)
(850 x 6000) / 5258* = 969 bhp
So, on to the 3,0 (You said 2,4, but I believe it's a 3,0 L engine from what I've read) L V6 then:
It produce 714 Nm (527 Lb.ft).
The X2010 rews a lot more compared to the Bugatti. 10.000 rpm's more to be exact.
(527 x 16000) / 5258* = 1603 bhp (This is a bit to much, but the engine does not produce max tourqe (the fighure I used calculating it's max bhp output) at max bhp (Usually, an engine produce more tourqe lower in the register, but produce less power due to the lower rpm's)
With these numbers, you could say that 527 Lb.ft is a huge number for a 3 L engine since a 3 L engine produce at around 250 Lb.ft (in a normal NA engine that is. Supposed to be mounted in an every day car).
An engine like this is put together with very expenive and specially made parts parts to make it able to rew so much. The Bugatti on the other hand have to last without service needed every 500 km (750 miles), because dispite it's price, is still an every day car.
*To get from pound-feet of torque to horsepower, you need to go through a few conversions. The number 5258 is the result of lumping several different conversion factors together into one number.
So with this in mind, the X2010's engine specs is actually something that could be made with the knowledge we posess today.
A quick example:
1. My car with a 4 L V8 produce 200 Nm (147,5 Lb.ft) at 3000 rpm
2. My other car, with a 2 L S4 produce 100 Nm (73,75 Lb.ft) at 6000 rpm
Wich engine produce the most Bhp at the given rpm?
Both cars produce the same amount of bhp.
1. (147,5 x 3000) / 5258 =
84,1 Bhp at 3000 rpm.
2. (73,75 x 6000) / 5258 =
84,1 Bhp at 6000 rpm.
I appologize if my english from time to time can be hard to understand, but I hope my post is understood for the most part. 👍
