it was mentioned in the megafactories or whatever it's called documentary on production of the Veyron

the problem with american muscle cars with near 1000bhp is they are generally bad, look at the Dodge Demon which turned out to be a bit of an embarrassment and a laughing stock of youtube

I think he means that they said the engine was roughly 33% efficient, hence 1000hp at the wheels means at least 2000hp being lost elsewhere.

Err......someone needs to go and have some maths lessons.

Veyron is quoted by VW as having 1001 PS, with the SS model having 1200PS, which will be flywheel figures, not at the wheels.

You can loose 2000hp from a starting point of 1011 or even 1200......

https://www.motorauthority.com/news/1102657_a-close-look-at-the-bugatti-chirons-monster-w-16-engine

"For Bugatti, generating power isn’t the biggest hurdle. The real issue is keeping temperatures cool. According to Bugatti, the Chiron’s engine can generate upwards of 3,000 hp in heat energy all of which needs to be dissipated. The solution are two cooling water loops, a high-temperature loop for engine cooling and a low-temperature loop for the aforementioned charge air. The high-temperature loop features one main and two auxiliary radiators with 37 liters of cooling water which are pumped through the entire cooling loop in about three seconds. The low-temperature loop is equipped with one radiator and has a water volume of 12 liters. This loop prevents the charge air from overheating in stop-and-go driving and urban traffic."

Yes. You. The average IC engine is about 33% efficient. Thus, 1000BHP out of the engine is a third of the heat energy produced by the fuel. Half of what's left goes out the exhaust pipe, half into the water cooling system. So that's 750KW for each.

Most ICE are around 25-35% thermal efficiency, if the Bugatti is around 33% its actually pretty good.

Actually, its more like 25%
And you still can't count as the Veyron doesn't produce 1000hp at the wheels, which is why things are going off at a tangent with TE stuff.
I still don't know why we're talking about a stty Veyron anyway in a thread about a real engine.

The Bugatti Veyron engine is a masterpiece. So is the gearbox. The Hellephant 1,000BHP is a crude dinosaur by comparison.

This is where I struggle with engines. The Dodge engine will be low cost, bomb-proof, easy to maintain, light, low centre of gravity, all of the things you want. Will produce an insane amount of power with an epic soundtrack to boot.

Or you can spend 10 times the money on a hyper-complicated engine that needs more radiators than a house, weighs as much as the moon, difficult to maintain, very specialist and gives you the same amount of power as the V8.

There must be something that's better about the expensive one that I'm just missing.

Not so light, COG high due to a huge supercharger on its head. Old world technology. Radiator requirements the same as the Bugatti Veyron. The Bugatti engine weighs 400Kg (880lbs). A 426 V8 with a supercharger is circa 600lbs. However, the Bugatti Cheyron version engine tops out at 1,500BHP.

From Bugatti website:-

"The thing about the engine weighing as much as it does is that it’s not explicitly designed to be the most power from the least weight. It’s designed to be a reliable and durable source of that much power. Even though it’s quad turbocharged, it doesn’t make even a hundred horsepower per cylinder, as Wallace points out. The idea is to keep everything sturdy enough to last.

It all fits in with the kind of engineering dominance of modern Bugatti, cars so overbuilt that they bludgeon obsolescence into submission."

PS. The Helliphant produces it's 1000BHP on race fuel.

This Hellephant is an aluminium small block. Yes, it's supercharged, but I'd be surprised if it weighs more than the Veyron engine, dressed.

Sorry, misread the units!

The Most Badass Engine You Probably Don’t Know About

http://shiftinglanes.com/2016/02/the-most-badass-e...

So who is Mercury Marine? Only one of the most well-known boat engine builders in the industry. So how in the world did they make their way into an automotive enthusiast’s website? When you build a Quad Cam LS, you get my undivided attention. They started with an LS7. They increased displacement to a massive 9 liters. To put it into perspective, roughly 500 cc more than the COMBINED displacement of all of Shifting Lanes’ cars. They then added their special sauce, the new heads pictured above. Oh, they also added 2 turbos. Why? Because why the fk not? Because Powwwwwerrrrrr! Because America, that’s why. This beast makes 1650 Horsepower. Stick that in your pipe and smoke it Bugatti. That’s a little over 206 horsepower per cylinder. That’s 1000 MORE horsepower than a brand new Corvette Z06. This monster can go in anything you want: a boat, a car, an incredibly over powered but totally awesome Cuisinart. Anything. In all seriousness, is anyone else thinking Mr. Hennesy should give these guys a phone call?

How is it a masterpiece, is it because even with turbos it makes more heat than power? It may look nice as coffee table but I’d say it’s unimpressive as an engine.

This is more impressive: £7.5k +VAT for a crate engine that, with a pair of Chinese turbos off eBay will make a reliable 1000hp out of the box. Built to take boost:

Good for 1500hp for those brave enough.

So, 9 grand plus some turbos. And some manifolds. And eveything else you'll need. I mean, it looks like a good foundation, but there's slightly more to it than that link and 2 ebay chinese special turbos,isn't there.

And pretty much all engines make more heat than power, including the one you've linked.

Once you figure out how to swap those numbers around, you'll be a rich man!

Say less than £20k fitted and mapped which I’d say is pretty good.

Absolutely, to me the veyron gearbox is more impressive than the engine, although I imagine youd struggle to get the same sort of emissions figures from the aftermarket solution.
