There gotta be some secrect in the engine.

Now i wish FRS, BRZ make this number on their 2.0. Just 280hp, and i am sold lol

 

There's no secret to a 2.0L engine making 355bhp with 26.1 boost. Anyone can make an engine that can do that. Such is proven by the number of aftermarket Evo X tunes that make more hp with lower boost.

The secret is making such an engine that is 1) reliable enough to be feasibly financially backed by a factory warranty, and 2) doesn't frustrate its owners with reliability problems even if it is backed by a factory warranty.

 

High boost, High horsepower, tiny 4 bangers just aren't my thing.

 

I love it......

 

That's a valid post you made there, Sir Gengar =)

Anyways, for those who may be a bit worried regarding how pushing too much power and pressure on a small engine may cause damage, those are valid concerns indeed...................BUT I believe that Mercedes Benz and AMG have done their homework and studies those possibilities as well (i.e. extreme heat and pressure).

Also read some quotes on the internet:

With that in mind, personally, I don't think that there is anything to fear in this regard =)

^^ nice find with that AMG engine picture

 

I think the part to be feared is that it's made by Mercedes-Benz.

 

Mercedes' motors have been stout. That's not been one of their weaknesses like BMW.

 

Certainly anyone feels safer with MB (and especially AMG) than BMW, but this is new ground even for AMG. Also, MB engines haven't been bulletproof. Even the M156 (which I have touted on this board as an incredible achievement, especially since it was an entirely in-house AMG project) had its reliability concerns.

 

The biggest issue with regards to engine failure under this much boost is simply reduced tensile strength due to heat. As posted, designing from day 1 to handle and remove the heat makes this not much different of an issue than, say, a NA engine rev'ing 9,000 RPM, in regards to the stresses on engine internals.

Anyone remember the R8 mules with the twin-turvo V10? I think all of them burst into flames as Audi simply couldn't figure out how to remove enough heat at a great enough rate. So instead they dumped a NA Gallardo engine into it.

Remember that fuel is exploding inside an engine. Adding boost simply increases the force of that explosion, with a pretty linear increase as boost increases. Heat, on the other hand, has a non-linear reduction in tensile strength.

 

This is true, although its worth noting that the M157 is being pumped with 18.5 pounds of boost in performance package AMG models. So at least they're not totally new to turbocharging.

 

^^^Valid point.

Also to add, MB and AMG have the M275 and M279 engines (which basically are two kinds of 6.0 liter V12 Twin-Turbo engines).............and so far, these seems to be quite robust.

Hence, I believe that AMG was able to learn as much regarding turbo charging

 

Just wanted to throw this in here!

on topic: i really like the exterior design
