Damn. That's impressive.

Exactly

I think the highest factory hp rating of the 4G was about 280. That’s a far cry from 500 from a car off the factory line that comes with a warranty. Sure the 4G can and has been tweaked to produce a good deal more but so can the new AMG offering I would say. The AMG can’t be on the ragged edge if coming off the line at its current number. There’s power left on the table at MB.

Does it come with a warranty? I'm sure that MB would be washing their hands of it and it'd probably be like puling teeth to get a 3rd party tuner to cover expensive MB warranty work. Say you screw the transmission or something in the driveline especially, I imagine you'd be fighting over both companies trying to wash their hands of it. It seems more like one of those "sounds good on paper" things. Yep, tuners have been making massive HP from small engines for a while....but a year or two down the road? Hell 5 years? If they aren't making the cars to last this long, then it's just a smoke and mirrors thing IMO, and even BMW and others aren't really doing this either, with some of the cars like the M5 and others that just can't keep their engine parts together for that long.

You’re likely correct, I jumped the gun and thought it was a straight up AMG doing. My apologies pikkagtr.

[Yugo]

No matter what it's butt ugly

[yco]

i d go for such a car to drive daily, track day, small vacations here and there.. except the color though..

[Leftkeylife]

Really love these! Such a wonderful car all around. Just wish they made it to the US.

having owned several DSMs and a slew of EVO's back in my youthful days
500 AWHP was kind of easily
bolt on turbo, TBE injectors/FP tune and E85 with some Kelford cams
and the rest is pretty much stock

I never had a 4g63, but I've had my 4b11T for over 10 years now at a modest ~380 awhp. Most rock-solid car I'll ever own.

big hp 4 cylinders are nothing new. SR20, 4G63, K20. Pretty cheap to build them up to put a hurting on a stock turbo F80.

Hell even the new TTRS with a stock trans, stock internals, stock turbo... will run a high 9 sec 1/4 mile and put the hurt on a tuned f90 of tesla p100.

Except for the giant lag below 3.5K because you put a bigger turbo that's harder to spin, bigger intercooler with more volume to fill, and so on. MB, BMW and others are doing a lot to eliminate this from new cars, so that you get torque down low and so they don't drive like "the widowmaker", but I wouldn't equate those old turbo engines with the new stuff. Yes, both turbo, but delivery is hugely different, which is important. Torque beneath the curve is what makes that F80 so good. A 600hp 2.0L that has to be revved up to 4K to start making power because you put a GT40R on there is not the same thing.

4k boost threshold? that's what rolling antilag is for

Is that bad for the engine internals? Is the reason why manufacturers are going to electric turbochargers and superchargers and other similar devices to eliminate this without the negative tradeoffs?

usually it's detrimental to the turbo(s) but they can always be rebuilt
my DSMs back in the day was not really built for anything but going fast in a straight line as cheaply as possible
it didn't even have paint in certain places

Why would they do that when they have a better engine in the S58 already making over 500 hp? As a person that owned an Eclipse with an FP Green turbo I can appreciate high output 4 cylinder engines but as I grew up I realized that 6 and 8 cylinder engines simply do high horsepower better.
