up to 620bhp from 555, 50kg lighter = over 500bhp/tonne. Full article: http://www.autocar.co.uk/news_article.asp?na_id=212946

Nice.
|
i saw an article about this car in car and driver magazine, and it says that they are detuning an engine that can produce 885lbs of torque down to 627lbs because they start to lose traction at 553lbs... go figure
|
If its using the same motor as the old one that is the old old AMG v12. They should use the new one thats in the SL65 and CL65. 604hp 738ft/lbs twin turbo https://www.nopistons.com/forums/pub...IR#>/smile.png

Sounds dodgy to me, AFAIK it is an AMG v12 and they were naturally aspitated so it would be impossible to change the torque by such a large margin.
Mark The new v12 was "detuned" from over 1000ft/lbs to 738 because they couldn't keep a gearbox behind it. |
Don't like the extra headlight.

Mark maybe... i quoted the exact numbers from the magazine in front of me |

Are you sure it's not power you're talking about? What size is the engine? 6.0litres?
Mark The new MB V12's are twin turbo, and yes, those numbers are right(for the AMG variant, at least) |
meh.
|
i like it!
|
Ok so you're talking about the engines in mercedes which have forced induction - because you can't change torque output on a naturally aspirated engine like that.

You know you can detune Naturally Aspirated engines. It's called heads that flow air poorly compared to the tuned ones and less compression. Along with ECU's that dont allow enough fuel/air, throttle bodies that arent as big, restrictive exhaust systems, smaller fuel pumps, smaller injectors, A/C, power steering, big stereo systems and neon.

with them new engines you could hook the comp up to a computer and **** it all up and such.

OK fair enough - but that BMW engine isn't far off a race engine and has German precision engineering on its side. Regardless it's not a million miles from 70lb ft/litre and certainly not the difference between "over 1000ft/lbs" and "738".
Mark How is that number hard to believe from a twin turbo intercooled 6.5l V12 (AMG variant)? The STi makes 120 ft lbs/l and the Evo 8 makes 136.5 ft lbs/l. 738 ft lbs from a 6.5l is only 113 ft lbs/l. The Evo MR makes 143 ft lbs/l, and 1000 ft lbs from a 6.5l would be 154 ft lbs/l. That isnt very much of a stretch. |
