BMW's New V8TT-Vastly Underrated
http://blogs.edmunds.com/roadtests/2...hotopanel..2.*
A new 750i made 391rwhp on a Dynojet and the engine is rated at 400hp SAE. If that dyno is accurate this engine should be rated at 450+hp at the crank. That factory rating is just

Why not both!!! The old Lancia Delta S4 rally car was both...turbocharged and supercharged. The supercharger engaged at low-RPMs and a clutch switched it off at higher RPMs to be only the turbocharger from that point on.

They sat turbos are for top-end while SC is for low-end grunt. More recently, BMW have been using smaller bi-turbos to help eliminate turbo lag and to produce low end grunt. I'm not hearing any complaints about their top end power either.
It'll be interesting if we ever see Bi-Turbos in our V8s.

Twin Turbo's in right set-up do both LOW-end + High-end, the V12TT as well as countless other smaller displacement engines have gobs of Torque off idle @ 1600-1800 rpm's on up! the lil' 335 V6 has great low end but runs out of breath up around 120+mph due to small turbo's
The V12 TT rules all, all hail earth rotating torque!

The Mercedes was almost as quick as the more powerful (and heavier) BMW—5.3 seconds to 60 mph versus 5.2
Its still only slightly faster than the 360hp s550, I thought it would be a bit faster with nearly 100rwhp more. And its not weight either cause the 750li is only ~120 pounds heavier.

The article above addresses that issue. They claim that car manufacturers heat soak the engine on turbo cars before bench testing it's horsepower rating on an engine dyno. That is why they claim that turbo cars perform better than expected on a chassis dyno...because how many owners heat soak their turbo engine before doing a pull on the dyno?.....

Yeah, I came up from the rear and he picked it up as I blasted past. So, I slowed down and let him catch up. Then I did my usual sit on his rear passenger fender and try to stay there. He punched it and so did I. I sat at the bumper easily and decided to go on past when the red light was approaching. Passed him like he was standing still at about 80mph. I stopped at the next light and waited. he got a rolling start since he was approaching as the light tunred and I punched it and caught him just as he past me and I was GONE!!
Are they supposed to be fast?

Of course, that's never a bad thing. I've been an enthusiast in turbocharged cars for a while, especially the Toyota JZ line, 2JZGTE and 1JZGTE and many more applications from other makers. I know quite well the wonderful aspects of a turbocharged engine and it's benefits in the street/modding scene. My latest research is on what your driving and what's in the E55....V12 BiTurbo M275 and M285 and the Supercharged 5.4 M113K.

Jangy, was it a brand new 2010 750il? Of course it's not going to be faster than you, it has less power and torque, and much more weight, but I would have to imagine that it isn't slow, I think with a chip these things will get to be pretty damn fast. Just wait till they put it in a 550i with a 6 speed stick!

I was at my old Bmw dealership yesterday saing hello to couple of friends that work there and one of them is the superviser. He was telling me that every single 750 that was sold came back b/c after 1500 miles half the motor dint worked. He said that it's the biggest p.o.s builed by Bmw.
