First dyno. 340 WHP
I hope the aftermarket really takes off on this car. Does anyone know what size the turbo is, or make and model?
Can't seem to find it anywhere.

I personally could not stand my Evo/Sti's in hot weather with the AC blasting...the cars just had zero grunt off the line and felt like they lost 200whp lol. The more power you make on a 2.0 the more lag you get, naturally, but I wonder if and how AMG has possibly alleviated this.
.
The twin scroll suppose to give you the advantage of accepting the air from two cylinders at a different pulse thus enhancing spool characteristic. The single scroll is just all 4 cylinders putting air on the opening and interfering a little bit on the flow.
Depending on internals, I'm picture a lot of people upgrading to bigger turbos, larger fueling/intake capacity, and if need be the internals themselves to get a lot more power out of these. I don't even want to think about what that would cost.
Needless to say, great numbers for a stock car but I just don't see much improvement without changing out major components.
Here is an interesting read I came accross this morning: http://***********.com/content.php?3...AMG-dyno-graph
Another thing that doesn't convince me is the watercooler intercooler. It seems like the water cooled intercooler"suppose" to offer better cooling than the air to air but a good FMIC with a decent size and shape does the job very well. Just thinking about having this hot water trying to cool a core doesn't make much sense to me, ironically I currently drive a car that comes from factory with a water cooled intercooler (or heat exchanger), this is a Passat TDI.

The Best of Mercedes & AMG

Let's look at another FI 4 cylinder car with strong internals.
A stock srt-4 dyno's around 230whp, 300whp can be extracted with bolt ons and tune. Granted a stock srt-4 doesn't push 26.1psi stock, circa 14-15 peak.
Turbo swapped srt-4 50 trims make 400+whp, This can be done relatively cheap, even the 50trim can run on stock internals.
While GT35 turbo srt-4's have broken the 500+whp mark. Others are even higher. Red Sled comes to mind.
Do not discount a car just because it is a 4 cylinder. This isn't 1970.

I think 400whp for fully maxed out (including all possible bolt ons) is the absolute max you would push it. The real question is, how much can the DCT and PTU in the transmission handle. The PTU that sends power rearward is a very small unit, I would be shocked if it can handle more than 400whp with launch control.
But original engine for sure. Also know of a couple 50 trims that are still doing great as well. I personally don't know anyone with a 500whp SRT-4. I am sure you can still find them on the SRT-4 forum. Do some of them blow engines, sure. Bound to happen when pushing the envelope or trying to out smart the tuner.
The CLA45 will be no different. The internals are there, now we just need the aftermarket.I personally think a CLA45 with a hybrid turbo setup (similar to N54 setup) with supporting mods will have no problem engine wise. I am more curious to see how the transmission will hold as others have said. Then again Mercedes is not known for its strong aftermarket. So, only time will tell.

Never experienced turbo lag unlike in the sl 500 i test drove before on the road... Imo the only issue with the a45 is that it sucks without the performance exhaust
I think the aftermarket will really take to the CLA45. We are going to see lot's of high horsepower versions of this car. Tuners will figure out what the true limits of the car is. I would not make an assumption on the limits until it's been fully tested. I remember back in 2004 when I put HKS 272 cams in my Evo and had it tuned at 320whp that numerous people expected me to blow up my motor. Now most people know that Evos can take a lot more then that on the stock block.

That's a massive gain from just a tune. And to top that off, Carlsson is an authorized MB Tuner, so Mercedes will still honor the car's warranty with their parts on it.
