How: Getting 700+ horsepower

[jambee888]

By theory, you need to produce 500+hp out of a normally aspirated engine, then add a high-boost supercharger to take it up to 700+ hp. AMG who has all the R&D money and resources in the world cannot get that much power safely and reliably from their 6.3-liter engine. Not to mention the issues involving the differential, transmission, torque rods and all other 'supports' on the vehicle. Can someone explain to me how is that physically possible?

I'm not sure who is getting 700+ hp from the MB V8, but I do know that my car should dial in between 650-700 hp. Current AMG cars do not have a 6.3 liter V8. Any current AMG using a 6.0 liter engine, is using a V12. If you figure that AMG is pumping out stock cars at close to 500 hp with 5.5. liter SCed V8s, it is not so difficult to understand where my car's hp projections come from.... larger displacement block and a higher boost Kleemann SC. As for the rest of the supporting components.... a) that is why each component for my car is being custom manufacturd/tuned and b) I think you would be surprised at the redundnacy MB builds into their critical components. AMG undoubtedly could build a 700 hp 6.3 liter V8, however, it wouldn't make alot of sense for a mass produced car,.

I wasn't talking about your car but thanks for the info.

It'd be nice to have that much power. But i think i'll settle for anywhere between 600-650HP with what i'm doing.

Superchargers are inefficient and unreliable, this is why AMG is abandoning them completely. The story started with the 32K, the old SLK and current C-class C32 didn't have enough room in their bonnet, so AMG had to superchrage the biggest 3.2 V6 and get their hp.

They couldn't make body modifications and shoehorn in a 5.5 V8 not until now anyways. At that time, a 500bhp engine was required to take the brand to new heights, hence supercharging successfully their 5.5 V8 and getting 500bhp out of it.

Supercharging wastes a lot of engine power from the crank and pulley connections, the AMG Lysholm (Jap IHI built) usues 91bhp out of the engine not to mention the horrendous fuel economy of 7mpg!

To combat this AMG are using the latets MB engine technology as found in the SLK350 engine. They have successfully developed a 6.3 Na V8 that pumps out a "reliable 500bhp" on the engine dyno, quoted from various magazines around the world. It should replace the 55K engine altogether. The torque of the engine is approx 600Nm, coupled with a 7G Tronic transmission, it should be a brisk performer. That being said, the 600 models are pumping out close to 600bhp at the crank, AMG does not underrate its motors as badly as MB does. (though I wish they did, I like pleasant surprises )

I fell somehow that the enw 6.3 engine should be turbocharged to produce close to 600bhp to make Ferrari Porsche and Lamborghini sweat that little bit more. Wishful thinking now, but who knows?

Who's crazy enough to shoehorn a 612bhp engine in a cruiser?

You must NOT have seen the E60 from AMG W210s with a
6.0 V 8 from AMG ...I Have seen Several E60s Non USA cars

probably true in the long run, the s/c engines won't last as long as n/a engines, but I think if you take care of any car, more than likely, the engine will last.

MB has won awards for their 5.4l Supercharged V8 when it was engineered and such

good post. One thing tough, the supercharger isn't running all the time, only when the engine requires it. Because of that, the engine will live quite a while - when taking care.. as you said

Isn't your auto tranny the BIGGEST limitation?? According to AMG, this was their biggest problem...thus, the new 7-speed auto can handle more power.
