Thanks for the compliments! As far as my defensive tone.. you have to put yourself in my shoes, me on Jalopnik proposing that a cam in block V8 is a superior architecture to the rube goldberg alternatives is sort of like when Galileo went before the vatican and told them that the Earth is not the center of the…

On who's dyno? What correction factor? HP measurement is a funny thing if you don't know exactly what's being measured and how. GM LS engines also well outdo their rated output.
If you want to go comparing non -stock configurations, we can do that. Here's a *naturally aspirated* LS powered Camaro.
A request in…

Well if we are going to get on the subject of what is possible, you can speculate all you like about what maybe might could be possible with this Mercedes.
Meanwhile, you can youtube naturally aspirated LS7s putting down well over 600 horsepower to the wheels with a cam and head swap all day long. That is if you want…

Explain to me how the Corvette is sold in Europe without meeting the same standards.

I can assure you, I know more about engines than you do. Displacement has almost no bearing on engine size, actual physical external size that is, or weight.
Riddle me this Batman. How is it that the BMW S65 V8 weighs 445 lbs and the LS3 weighs 430 lbs? How is it possible that the BMW engine is also externally larger?…

The point is that you implied, as many people incorrectly believe, that displacement and economy are have a direct relationship. This is patently false, and I used the example of the *naturally aspirated* S65 V8 to demonstrate this fact. Given that both engines are naturally aspirated, port injected, and were…

Poor assumption. Uses more gas? When? BSFC is a funny thing depending on where you want to measure it. Do you mean fuel economy? I hope so.. because then you might learn something today. Go to the EPA page and look up the fuel economy from an E92 M3 and compare it to an LS7 corvette. Cliff notes: The S65 4.0 in the M3…

And displacement is what? Fill in the blank here.. what is in "displacement" that matters in reality? Do you know how displacement is calculated? If you do, tell me what is in that space, and then get back to me. If anything I want to know more about the space occupied by actual matter that is not air. In that…

LS9 also makes a lot more power. LS7 makes the same power as this thing and weighs less. It's also smaller externally. And please explain how Euro6 standard are more stringent than CARB standards.
Who cares how much hp per liter it puts out. It's perhaps the most irrelevant thing you could try and measure. It has…

Euro 6 standards are less rigorous than CARB. Try again. And the AMG weighs what it weighs because that's what it weighs. Your arguments make absolutely zero sense in the realm of reality. Here's reality: This engine is the same weight and puts out the same power as an LS7. The LS7 has no turbos, 1 cam, and port…

But then it's not an LS7. Just like this mercedes pile is not the same engine without the turbos. Instead of talking about stuff that does not exist, lets talk about stuff that does. LS7 is lighter and makes virtually the same power without even the benefit of direct injection. 1 cam. Naturally aspirated, smaller…

And what exactly are they liters of? What material is contained in these liters?
You say this engine is a ton more efficient.. which efficiency metric? BSFC? FMEP? EPA fuel economy? Power to weight? Power to external volume?
I can tell you that this engine is already *not* better in WOT bsfc, Fmep, power to weight,…

No shit sherlock. Tell me how much power that AMG engine makes without the turbos.

Displacement doesn't actually measure anything except a mass-less void (ignoring the air). All it's going to tell you is roughly the absolute minimum size an engine can be and we are no where near that in any engine.
I can fit a 2 liter bottle in my glove box but can't fit a 2 liter engine in there.
This mercedes pile…

It weighs 460 lbs bro. That's more than a 7 liter LS7. And the external dimensions of this thing are freaking huge, look at those pictures.
Newsflash: Displacement isn't a measurement of anything except an internal volume. Engines are way bigger than their displacement. Some much more so than others (like this one)…

LoL. This thing has 2 turbos, 4 cams, a shizload of valves, and external dimensions that make an old school chevy big block look small..
And it makes the same power as a Chevy LS7 with 1 cam, no turbos, half as many valves, and the *same weight*, 460 lbs! (actually the LS7 is a lot less if you don't include the…

Ok I just read the article more carefully. I see that it was press event so the guy driving may not have been you and that you left already. I got excited about this coincidence and rushed my reply :). Let me know if you go to Sicily sometime. I'll be there and my kart offer still stands. (We can run real cars too if…

DUDE!!!!!!!!!!!!!! I SAW YOU. Im here on vacation, What an absurd coincidence! . Yesterday (or was it the day before?) we left Ronda and drove to Granada and I saw you on the way coming the other direction. We drove right past ascari circuit and i wanted to check it out but the gate was closed. If you are still in…

As an American living in Europe this article made me literally laugh out loud. I still have a shit eating grin on my face too. Why? Because American car snobs that don't really know about cars, are all about everything Europe is doing and how it's better. Particularly Diesel. I think they do this to seem more…

Did you watch the video? Because the part about the tire generating the forces is pretty much what Mark Steilow said. It was a one minute promo bit, did you expect a full thesis on the issue? He gave a quick and dirty explanation for the average car guy.
