Oldtimer Project: Brutus

[Killrob]

This one is true to its namesake

http://www.spiegel.de/auto/aktuell/0,1518,760586,00.html

One of those classic rockets... originally from around 1925, now rebuilt and tested.
It has a 46 liter (sic!) V12 engine with 750 PS and around 10000 Nm torque.

The pictures linked in the article are really nice too hehe, especially the Bratwurst grilling.

Cheers!

I Love these silly cars!


See also Rover SD1 with Meteor engine (un-supercharged, and less lightweight Merlin) http://www.youtube.com/watch?v=f1BnhZsS8a0

Haha, love that guy in the video you posted, tough to be more car-nerdy, skillful and cool than that

[Fenris]

I'd love a Merlin in a road-legal car one day...

But Killrob, 10000 NM?!? Really? I have a hard time believing that, given that the 37.4 twin supercharged diesel in my tank puts out a little under 3000, and the larger twin-turbocharged 47.6 litre in the Leopard 2's I salvage under 4000 NM. And this engine is both older, and lack the diesel-torque. Not blaming you, as I see you took it from the article, just trying to put things in perspective.

[Killrob]

Hmm, yes, 10k Nm does seem a lot when comparing it to the numbers you state, Fenris!
Maybe it can run pretty high compression due to the use of aviation fuel? No idea... the wiki page for this motor does not state the torque as far as I can see:

http://de.wikipedia.org/wiki/BMW_VI

But also... at 1700 rpm, you need quite a bit of torque to produce 750 PS

[Killrob]

With the link that daffy posted somewhere else, we can actually check the torque

HP = torque X rpm / 5252
Rearrange: torque = HP / (rpm / 5252)

With our numbers that is:
torque = 750 / (1700/5252) = 2317 Nm

Which s much more in line with what Fenris stated. So I don't know where they get that value from... maybe the engine has it's maximum torque somewhere around 800 rpm or something, but I still don't think it can increase a factor of 4 there.

Just download this handy program:

Its for modding but you can also look at a torque curve in relation to horsepower as in that program you can only set torque and horsepower is calculated.

[zeussy]

maybe output torque the otherside of the torque converter it must have?

[Zsolti]

Not the best count, it may be a little more

hahaha, ive seen that car in sinsheim, thats just madness

I have seen the Brutus a couple of years ago at the Techno Classica in Essen/Germany. And they fired the engine up - indoor! It was great!! The Bratwurst tasted a bit strange. Haha!
